Design Guidelines: Typical Components
Technical Information and Application
The recommendations provided in this document have proven successful for most installations; however,
extreme or unique conveyor designs should be reviewed by an Intralox representative. There are two important
considerations:
• Intralox ThermoDrive belting must never be driven with tension (several inches of excess belt accumulation is
preferred)
• Ensure that position limiters are seated correctly in place at the drive section of the conveyor
Failure to follow the guidelines presented in this manual could result in improper performance of ThermoDrive
belting, voiding the product warranty.
ThermoDrive Design Basics
DO…
•
•
•
•
Ensure that the belt has extra length and hangs loose on the return path
Ensure all transitions, guides, and sprockets are at or above the minimum bend radius
Limit the drive sprocket engagement to 180° or less
Install position limiters in line with each drive sprocket (on flat belting), from about the 4:30 to the 5:30 position
relative to the drive sprockets
• Lock all drive sprockets in position, in line with their corresponding position limiters
• Lock all support wheels/sprockets on idle shafts
• Ensure that shafts are squared
DON’T…

Design Guidelines: Belt Support
Carryway
WEARSTRIP CARRYWAYS
There are various methods for supporting Intralox ThermoDrive belting in the load carrying portion.
Wearstrip arrangements
1. Straight, parallel rails: These supports consist of strips,
Belt travel
either UHMW or 300 Series Stainless Steel. Contact Intralox
Technical Support Group for recommendations specific to
your application.
A
• One rail should be indented 0.5 in (15 mm) from each
B
edge.
• The recommended maximum lateral centerline distance
A - Gap for Thermal Expansion
between rails is 6.0 in (152 mm). This dimension will
fig. 2.0
B - Joint stagger of the wearstrips
vary depending on the density of product and should be
verified by an Intralox representative.
• Note: Special consideration must be given to any intermittent joint in the support rail. At the joint, ensure
each end is chamfered to allow for smooth transitions and to avoid catchpoints. Failure to do so will
cause interference between the drive bars and the leading edge/trailing edge of the downstream rail, resulting in rough belt operation and possible damage to the belt or rail. Stagger
rail joints to further reduce the chance of joint/drive bar interference. An example of joint stagger
is shown in Fig. 2.0. Break all sharp corners on the carryway rails.
120513
53361_WEARSTRIP-DETAIL_1_bw
2. Chevron array: By placing the strips in an overlapping “V” or chevron array (Fig. 2.1), the underside of the
belt is supported across its full width as it moves along
the carryway. The angled surfaces can be effective
in removing gritty or abrasive material from the underside
of the belt. A minimum 0.4 in (10.2 mm) gap is recommended between the points of the wearstrip to reduce
B
debris build up. This arrangement is also good for
heavily loaded applications. By reducing the spacing
between adjacent chevrons, the bearing load on the
strips and the belt’s unsupported span is decreased.
Standard flat wearstrips can be modified to form the
C
fig. 2.1
chevron array.
• The recommended maximum lateral center distance

specific to your application.
53361_CHEVRON-ARRAY_1
• This dimension will vary depending on the density
of product and should be verified by an Intralox
representative.
• For chevron arrangements, ensure that the leading edge of the wearstrip is chamfered to reduce catch
points. Failure to do so will cause interference between the drive bars and the leading edge of
the downstream rail, resulting in rough belt operation and possible damage to the belt or rail.
Break all sharp corners on the carryway rails.
In cases where a heavy product is being loaded, a full width Ultra High Molecular Weight Polyethylene (UHMW)
plate may be used to help absorb the impact.
NOTE: ThermoDrive belting is not to be tensioned. Consult with the Intralox Technical Support Group for conveyor design and belt specification assistance prior to ordering.

Design Guidelines: Belt Support
Wearstrip types and sizes
Intralox can provide the following wearstrip material types:
•
UHMW flat wearstrips are available in 0.25 in (6.4 mm) thick × 1.25 in (31.8 mm) wide × 10 ft (3 m) lengths.
The UHMW wearstrips should be attached with plastic bolts and nuts in slotted holes to allow for expansion
and contraction with temperature changes. Contact Customer Service for ordering assistance.
•
Intralox also recommends the use of 300 Series Stainless Steel or UHMW Flat Stock (1 in (25.4 mm) wide
minimum).
Carryway types
Intralox recommends the following material types for use as carryway support rails:
•
Smooth surface UHMW Polyethylene—free of rough machine marks
•
Smooth surface 300 Series Stainless Steel—free of rough weld seams
WEARSTRIP DESIGN CONSIDERATIONS
Temperature limits
UHMW is recommended to 160°F (71°C). Note that belt temperature limits are 140°F (60°C) for Polyurethane
and 170°F (77°C) for XT.
Thermal expansion and contraction
Installation of Intralox flat and angle wearstrips should allow for thermal expansion and contraction. The use
of slots when mounting will accommodate changes in dimensions due to thermal expansion. Be cautious to
account for gaps between wearstrips when changes in length occur from thermal expansion. For reference, see
Figure 2.0 (example) and Figure 2.2 (coefficient of thermal expansion). At operating temperatures of 100°F
(38°C) or less, it is sufficient to bevel-cut the opposing ends of strips at an angle of 30° from the horizontal and
provide a clearance gap of 0.30 in (7.6 mm). At temperatures exceeding 100°F (38°C), the angle of the cut
should be 60°. The clearance should be determined from thermal expansion calculations. It is recommended
that wearstrip joining locations be staggered for smooth belt operation.

Design Guidelines: Belt Support
Returnway
Intralox ThermoDrive belting is installed with ZERO PRE-TENSION. Since a belt installed properly will
be loose on the conveyor, belt sag in the returnway should be expected. In order to properly control the shape and
location of this sag while ensuring the belt is not pre-tensioned, the belt must have sufficient support in the returnway.
Catenary sag, when implemented correctly, is critical because:
• It indicates zero pre-tension in the belt
• It accommodates belt storage from changes in length due to load or
changes in temperature
• It enables belt lifting and access for sanitation
Possible returnway supports include continuous rails (Fig. 2.3, A), shoes
A
(Fig. 2.3, B), and rollers (Fig. 2.3 C). On many conveyors, a combination
of continuous and intermittent supports is desirable.
When using continuous support rails:
B
fig. 2.3
• The lateral center distance between rails should not exceed 12 in
C
(305 mm)
• The rails on the outer edge should be 2 in (51 mm) to 3
in (76 mm) from the edge.
Further, to accommodate fluctuations in belt length, at least
one open span is required in the returnway. This is especially
true in longer conveyors (shaft to shaft length over 25 ft
[7.6 m]), where at least 1/3 of the returnway should have
catenary sections for belt length control where remaining
conveyor length uses a returnway of continuous support.
B
Full-length rail support in the returnway is not recommended
A
because there is no room to accommodate changes in length
(accumulation zone needed).
fig. 2.4
When using intermittent supports, they should span the full
width of the belt if possible.
110813
53361_RETURNWAY+DIMENSIONS_2
• Roller/shoe spacing down the length (Fig. 2.4, Dim. A) should not exceed 72 in (1829 mm).
• It is important that ThermoDrive belting not be forced to bend to a smaller backbend diameter than the recommended
minimum backbend diameter (See Product Line Manual for minimum backbend diameter). Doing so, in any direction,
will lead to belt damage, including premature failure of ThermoDrive belting.
In general, we recommend 3 ft (0.9 m) spacing of return rollers and one span of 4-6 ft (1.2–1.8 m) for accumulation.
This accumulation zone needs to be closer to the infeed for inclines and closer to the drive end for horizontal
conveyors.
In cases where obstacles exist and the accumulation zone needs to be located around the obstacle, be sure to adjust your
returnway support to avoid contact with these obstacles. The solution for this situation could be different roller spacing,
a short set of rails, or even shoes. As you eliminate dynamic elements (rollers) and replace them with static (rails,
shoes), friction will increase in the returnway..
The belt should be installed so that it has an appropriate amount of sag for all unsupported spans (Fig. 2.4, Dim. B):
• Recommended catenary sag at initial set-up is equal to 1.5 in (38 mm) of catenary sag (Fig 2.4 Dim B) per 1 ft
(0.305 m) of span (Fig. 2.4 Dim A); this can change depending on conditions such as load, temperatures, etc. Depth
of catenary sag will vary as the span of return rollers is adjusted (e.g., max roller span of 6 ft (1.8 m) would require
a minimum catenary sag of 9 in (229 mm). Depth of sag will vary during belt operation according to belt speed,
temperature change, and product load fluctuations. Ensure zero pre-tension in the conveyor.
Returnway rollers and shoes commonly have flanged shoulders to assist in containing the belt.

Returnway with Flights
Given that all of the above recommendations for the returnway still apply, the
following are recommendations more specific to belts with flights.
•
•
•
•
•
Continuous rails are recommended for returnway support of Intralox
ThermoDrive belts with flights (Fig. 2.5).
Flighted belts always need an indent of at least 1.25 in (32 mm); returnway
support rails should be positioned to support the belt 0.25 in (6.35 mm)
fig. 2.5
from the flights (Fig. 2.6, A).
It is possible to return on 90-degree flights. Contact Intralox Technical
A
Support Group for recommendations specific to your application.
Never return on scooped or 75-degree flights.
fig.B2.6
For flighted belts used in an Incline-to-Packaging application
(Z-Conveyor), please refer to the guidelines outlined in the “Supplemental Design Guidelines for Incline-toPackaging Applications”.
Center Notches
When using a center notch in the belt, the following recommendations apply to both the carryway and returnway of the
conveyor:
• Limiters should be used at the drive in the center notch
• Rails should never contact the edges of the flights or be used for containment/tracking purposes. Maintain 0.125
in (3.2 mm) to 0.25” (6.4 mm) clearance between the rail and flight edge.
• Rails need to be chamfered at the infeed and outfeed to prevent catch points. Break all sharp edges.
• Belts with center notches may need belt support (e.g., hold downs) at all transitions. Contact TSG for applicationspecific recommendations.
Belt Length Fluctuation
One of the principal functions of the returnway is to properly accommodate
the increase (or decrease) in the length of the belt while operating. Therefore,
conveyors should be designed to incorporate a suitable location within the
returnway where the temporary length change of the ThermoDrive belt can
be accommodated. The natural location of belt accumulation is immediately
following the drive sprockets (Fig. 2.7) or at the lowest vertical section of the
conveyor. The path the belt takes through the returnway will need to be free
of obstructions or catch points (for example: drip pans, structural members,
etc) at both the belt minimum and maximum expected lengths.
fig. 2.7
Please contact the Intralox Technical Support Group for recommendations specific to your application.
110713
53361_ENDDRIVE+SAG_1
Belts will either elongate or contract in operation because of these factors:
Temperature variations
Assuming belts are installed at average ambient conditions, normally about 70°F (21°C), any significant temperature
change in operation will result in contraction or expansion of the belt. Be sure to consider belt material’s full
operating cycle (production, sanitation, etc.) when determining the effect of thermal expansion and contraction.
The magnitude of the thermal contraction or expansion is dependent upon the belt’s material, the difference in
temperatures, and the overall length of the belt. A belt which contracts due to cold temperatures may cause overtensioning and excessive shaft loads if surplus belt is not provided.
Elongation (strain) under load
All belts will elongate if load is applied. It should be noted that under most conveyor conditions, only the carryway
length needs to be considered when determining belt elongation.
NOTE: ThermoDrive belting is not to be tensioned. Consult with the Intralox Technical Support Group for conveyor design and belt specification assistance prior to ordering.

12
Design Guidelines: Belt Support
As previously mentioned, changes in belt temperature will change the overall length of ThermoDrive belt based
solely upon its Coefficient of Thermal Expansion (CTE). This becomes critical when ThermoDrive belting is made
to length at a temperature other than the one at which it will actually run. For instance, a belt will often be cut to
length at 70°F (21°C), even for a conveyor intended to run at 20°F (-7°C). In order to size the belt correctly, the
Coefficient of Thermal Expansion must be used to calculate the amount the belt will shrink due to the 50°F (28°C)
temperature decrease from the time the belt was cut to length to the time that it is running on the conveyor. If this
calculation is not done properly, the length of the ThermoDrive belt may be significantly wrong.
Examples: Determining the temporary fluctuation in belt length relative to temperature.

Consider thermal expansion in the width direction as well. At maximum operating temperatures, the belt edge
clearance (“D” dimension in fig 2.8 above) needs to be 0.125 in (3.2 mm) on both sides of the belt.
USE OF ADJUSTABLE IDLE SHAFTS
There are many benefits to having an adjustable idle shaft:
• The shaft can be moved to make incremental adjustments in belt length and returnway position.
• For belt installation or repair, the shaft can be moved full forward to provide the shortest path.
• It may facilitate conveyor cleaning.
When using adjustable idle shafts:
• The take-up is not required for drive-sprocket engagement
• Meant for fine-tune adjustments to belt path position only
• Avoid pre-tensioning the belt; belt should stay loose to facilitate cleaning and sanitation
Note about belt length: Since ThermoDrive belts do not require return-side tension to operate, it’s permissible
111113
or even desired to have significant “excess” belting on the return side of the conveyor.
For example, having
excess belt in the returnway would allow a sanitation crew toTHERMALEXPANSION_1_bw
lift the belt from the carryway, giving access to
clean the carryway, frame, sprockets, and shafts. In every case, ensure that the belt path is completely free
from obstructions such as cross members, bolts, wiring, etc.
NOTE: ThermoDrive belting is not to be tensioned. Consult with the Intralox Technical Support Group for conveyor design and belt specification assistance prior to ordering.

Design Guidelines: Belt Support
13
Catenary sag
A belt hanging under the influence of gravity between two supports will assume the shape of a curve called a
“catenary.” The specific dimensions of this curve will depend upon the distance between supports, the length
of hanging belt, and the belt’s weight.
In most cases, the actual shape of catenary curve is not important, but the conveyor designer is interested in
the excess belt stored in the returnway section. The excess belt in each section, X, is found from:
X = (2.66 × S²) / D
where: X = excess belt, in (mm)
S = sag, in (mm)
D = distance between supports, in (mm)
Determining where length changes will be accommodated can be controlled by creating a larger span where
the sag is preferred. When using continuous rail supports in the returnway, length changes may be accommodated by creating an open span in the rails. Regardless of returnway belt support method, typically, one 6
ft (1.8 m) longitudinal span will be sufficient to control where the belt length accumulates (Fig. 2.9, Dim. A).
After thermal elongation and belt strain effects have been considered and a “range” of belt lengths has been
calculated, it is important to design the returnway to be able
to accommodate the belt at both the “shortest” and “longest”
predicted lengths. It is quite possible that multiple catenary
sag sections may be required to properly store belt, though
remember that sag will not distribute evenly—it generally will
collect in the longest sections and where belt tension is lowest.
In most applications, this change in belt length will be relatively
insignificant and will thus require nothing more than a designated
location for accumulation (as needed).
A
fig. 2.9
For long, heavily loaded conveyors (above 100 ft (30.5 m)
and 50% Allowable Belt Pull - ABP) that utilize continuous
support rails in the returnway, Intralox Technical Support Group should be consulted to ensure that sufficient
space has been designed for belt length accumulation.
110713
53361_ENDDRIVE+SAG_2
For example, a horizontal conveyor 30 ft (9.1 m) long and 30 in (762 mm) wide, with a product load of 200
lbs (90.7 kg) will only accumulate 0.125 in (3.2 mm) of temporary belt length. However, a horizontal conveyor
100 ft (30.5 m) long and 30 in (762 mm) wide, carrying 4000 lbs (1814 kg) will accumulate 9 in (228.6 mm) of
temporary belt length.

Design Guidelines: Belt Support
CONTAINMENT
Containment of ThermoDrive belting is accomplished along the belt edges. The drive bars on the bottom surface
of ThermoDrive belting extend to the edge of the belt, allowing for the lateral rigidity required to effectively contain
the belt. Conveyor side rails, frames, containment blocks, or flanged rollers (Fig. 2.10) can be utilized to contain the
belt. Recommended clearance between the belt guide and the edge of the belt is a minimum of 0.125 in (3.2 mm)
per side (refer to page 12 for Coefficient of Thermal Expansion calculations).
•
•
•
•
•
•
•
It is recommended that the containment blocks have a minimum 0.25 in (6 mm) chamfer and 0.03 in (0.8 mm)
transition radius to avoid damage to the belt edge (Fig. 2.11).
The flange height of a return roller should be .75 in (19 mm). (Fig 2.10)
See page 40 for Intralox’s stocked flanged rollers.
Chamfer both sides of containment block-leading and trailing ends (Fig 2.11). Minimum length of containment
block should be 6 in (150 mm). When containment blocks are used, spacing should fall into the range of 6-8
ft (1.8-2.4 m). Applications where side loading is present need longer containment blocks. Full-length containment rails are preferred at areas where side loading or diverting product occur.
All hardware should be countersunk below the level of the belt.
Material recommended is UHMW; contact Intralox Technical Support Group for other alternatives.
Drive shafts should be square with conveyor frame (best practice).
NOTE: To avoid mistracking, the use of perpendicular surface to belt edge (not angled/tapered) is recommended.

Design Guidelines: Framework
15
ThermoDrive belting has been designed as an optimal hygienic solution to greatly reduce the time and effort required
to clean the belt. In order to fully realize the benefits of this hygienic solution, the conveyor should be designed to
allow for a loosely fitted ThermoDrive belt. The loose fit will allow the belt to be simply lifted and cleaned in place or,
depending upon the conveyor design, easily removed from the conveyor so that the conveyor may be easily cleaned.
The framework configuration should allow for appropriate sanitation and maintenance as required in the specific application. Further, if the conveyor design requires ThermoDrive belting to be delivered open-ended, an access window
of no less than 24 in (610 mm) can be included to accommodate a ThermoDrive splicer. If the conveyor is designed to
accept an endless belt, then a splicer and splicer window is not required.
NOTE: ThermoDrive belting is not to be tensioned. Consult with the Intralox Technical Support Group for conveyor design and belt specification assistance prior to ordering.

16
Design Guidelines: Sprockets & Related Items
Shafts
Shafts should be fastened to the conveyor frame level and square with the belt’s path. Further adjustment is not
required. In most cases, the standard 1.5 in (40 mm) square shaft is sufficient to minimize deflection. All drive sprockets
and support wheels should be fixed/locked on the shaft with retainer rings, heavy duty locking collars, or self-set
retainer rings. When utilizing retainer rings, shaft corners require grooves.
MACHINED TO CUSTOMER SPECIFICATIONS
After the stock is cut to length, the raw shaft is precision
straightened. The bearing journals are turned, followed
by the cutting of retainer ring grooves, keyways and
chamfers*. The final step is a thorough, quality control
inspection before shipping. Contact Customer service
for a form to fill in specifying shaft dimensions.
*If the shaft is to operate under high belt loads, retainer
ring grooves are not recommended. Self-set or split
heavy-duty retainer type rings are recommended in
these cases. Contact the Technical Support Group for
retainer ring recommendations.

Design Guidelines: Sprockets & Related Items
Drive Sprockets
It is important to install drive sprockets at the outside edges of
ThermoDrive belting (Fig 4.2). Although it is not necessary that
sprockets have freedom to move laterally, a limited amount of
movement is allowable. Lateral movement of the sprockets on the
outside edge of the belt should be limited to +/-0.125 in (3 mm). All
other sprockets may laterally move +/-0.25 in (6.4 mm).
•
•
•
The centerline of the sprocket should have a 1 in (25 mm)
indent from the belt edge.
To achieve published belt pull capability, the maximum center
distance for sprockets is 3 in (76 mm).
fig. 4.2
The belt must not “hammock” between drive sprockets during
operation. Additional sprockets are required if the “hammock” depth is greater than 0.25 in (6 mm).
110813
53361_ENDDRIVE-SPROCKETPOSITIONS_1
Idle Shaft (non-driving) Considerations
Conveyor Entry (Infeed) of End Drives:
• Spacing of segmented discs = 6 in (152 mm) maximum center line spacing when using 1 in (25 mm) wide discs.
• Infeed belt wrap should have an arc of contact of at least 120 degrees to avoid vibration.
Conveyor Exit (Outfeed) of Center Drives:
• Solid roller recommended to prevent hammocking between sprockets.
• 3 in (76 mm) disc spacing (center to center) is recommended when using 1 in (25 mm) wide discs.
Idle Shaft Belt Wrap
Intralox ThermoDrive belting is designed to function on a range of roller diameters. However, minimum recommended roller
diameters are achieved only by using Intralox designed rollers. Preferred roller materials are UHMW Polyethylene.
ThermoDrive belts are installed without pre-tension, and therefore
may not accurately conform to certain idle end roller diameters. As
a general rule, increasing the roller diameter and/or using a thinner
belt will enhance the belt’s ability to conform to the roller diameter.
However, when smaller diameter rollers are necessary, creating
belt drag in the returnway area immediately before idle-end rollers
will aid the belt in accurately conforming to these smaller roller
diameters. To create belt drag, it is recommended that returnway
rails, etc., be placed immediately before idle end rollers (Fig. 4.3).
A

Intralox recommends solid idle rollers for center-drive arrangements.

Design Guidelines: Position Limiters
19
Position Limiters
Position limiters are necessary to ensure proper, continuous engagement between Intralox ThermoDrive belting and
drive sprockets without the use of pre-tension.
The ideal position limiter is a shoe that spans an arc length larger than one belt pitch (Fig
5.1). Other objects, such as rollers and scrapers have proven successful as position limiters.
Contact Intralox Technical Support Group for further assistance.
•
All position limiters must be mounted where they can support the seated belt directly
at the drive sprockets.
•
A small gap of 0.005 in (0.127 mm) to 0.05 in (1.27 mm) should be maintained between
the seated belt and the position limiter (See dimension A on Fig 5.1). If the position
limiter is too far from the belt it may cause engagement issues. Stainless Steel feeler
gauges are recommended to verify this dimension.
•
A
fig. 5.1
The position limiter does not exert pressure through the belt and on to the sprocket.
The limiters need to be rigidly mounted to resist any tendency the belt may have to lift off of the sprockets.
110813
53361_LIMITER-GAP-DETAIL_1
•
Limiters that pinch the belt against the drive sprocket may cause intermittent drive disruption and create noisy

belt/drive operation.
•
Limiters should be installed laterally across the width of the belt (Fig 5.2) and remain in-line with the drive sprockets
(Fig 5.3).
•
If a flighted belt is used, position limiters should be placed in plane with the outside drive sprockets (Fig. 5.4). In
order to ensure that the flights do not impact these limiters, the lateral movement of the belt should be sufficiently
contained with 0.125 in (3.2 mm) to 0.25 in (6.4 mm) clearance required..

Design Guidelines: Position Limiters
END DRIVE
For typical “pull” in unidirectional applications, the position limiters should be
installed approximately at the 5:30 position1 when the belt is running in the
clockwise direction (Fig. 5.5). This provides 165° of belt wrap around the drive
pulley, which is ideal in most applications. In applications where the position
limiter cannot be placed in this location, it should be placed somewhere between
120° and 180°. It is important to ensure that no device causes the belt to wrap
around the sprocket more than 180°.

CENTER DRIVE

All center drive configurations must use a drive sprocket with no fewer than ten teeth (6.5 in [165

Retrofitting a Center Drive to Work with Intralox ThermoDrive Belting
Although most traditional center drive configurations can be easily retrofitted to work with ThermoDrive belting, the use
of ThermoDrive belting provides the designer with the opportunity to use simpler configurations. To better understand
the benefits of these new configurations, the typical retrofit options will be addressed first. As with the end drive, in any
center drive scenario, it is important to ensure that no device causes the belt to wrap around the sprocket more than
180° nor exceed the minimum backbend radius (see the Intralox ThermoDrive Product Line Guide for the minimum
backbend radius for each belt).
The following should be done only when retrofitting an existing center drive conveyor of conventional design. If the
conveyor is unidirectional, one position limiter must be placed over the last engaged drive bar, just before it leaves
the sprocket in its direction of travel, bypassing the existing load-bearing roller. If the conveyor is bidirectional, there
must be two position limiters used, one for each direction, bypassing both of the existing load-bearing rollers. If these
modifications are not practical, the Intralox Technical Support Group should be contacted.

Drive Layout for a New Center Drive Conveyor
When a new conveyor is being designed to use ThermoDrive
belting, there are two basic configurations recommended.
Neither of these configurations rely on achieving 180° of
belt wrap, but rather use approximately 70° of belt wrap
and use of position limiters. This reduction in belt wrap
eliminates the need for the robust load-bearing rollers of
the conventional configuration and allows the designer to
configure a more compact drive system.

fig. 5.7
7:30
For a bidirectional drive, two position limiters should be
installed at the approximate 4:30 and 7:30 positions (Fig. 5.7).
It is critical that all position limiters for bidirectional center
drives are not smaller than the minimum backbend diameter
rated for the particular ThermoDrive belt being used.
For a unidirectional drive, two belt position limiters should
be installed. One position limiter at the natural infeed and
another at the discharge location on the sprocket, approximately located at the 6:00 and 8:30 positions, respectively
(Fig. 5.8). In all cases, a minimum of three drive bars must
be seated on the sprocket after the position limiters have
been installed.

Design Guidelines: Scraper
Scraper Recommendations for ThermoDrive
When scraping ThermoDrive belting, it is important to design and mount your scraper in the proper position to maximize
performance as both a scraper and a position limiter. Scrapers may require adjustments over time as this component
can wear with use. In the figure below, there are 5 key dimensions to note when locating a scraper on your conveyor:
a, b, X, Y, and Z.
165°
X
β
Y
Z
α
Figure 1 – Locating a scraper to maximize performance with ThermoDrive Belting
a = Face Angle = 45°
The face angle, a, is the angle at which to prepare the face of the scraper in relation to the scraper itself.
b = Mounting Angle = 45°
The mounting angle, b, is measured from the center line of the conveyor. This is the best angle to minimize product
accumulation and still provide good beam deflection.
X = (Outer diameter of the sprocket/2) + (cover thickness of the belt)
The scraper will act as a limiter as well as a scraper when placed at 165 degrees from top dead center (reference the
centerline of the shaft). This dimension will vary with sprocket size and belt cover thickness. To be effective, scrapers
must contact the surface of the belt, so place the scraper up against the belt to where it is just touching the surface,
but not pinching the belt. Pinching the belt can cause surface damage to the belting, accelerated wear on the scraper,
and can compromise belt to sprocket engagement in extreme cases.
Y = Face width
Minimizing the face width, Y, will help prevent product accumulation on the scraper. Minimizing scraper deflection is
more important than minimizing face width. Contact Intralox Technical Support Group (TSG) for additional support.
Z = Scraper Thickness
Scraper thickness is determined through deflection calculations and will vary based upon the width of the belt, the
load on the conveyor, and the design of the scraper. The scraper needs to do two things: scrape and maintain belt to
sprocket engagement. Contact Intralox TSG for additional support.
Deflection Considerations:
When designing a scraper for a given conveyor, the design of the scraper must be of sufficient stiffness to minimize
deflection away from the belt to 0.010 inches or less at the center. If the scraper is allowed to deflect:
Design Guidelines: Scraper
23
•
Product yield will not be maximized.
•
It will be less effective as a scraper and could allow product to hang up between the belt surface and the scraper
(product jams).
•
It will be less effective as a limiter and, in extreme cases, will allow the belt to jump on the sprockets.
Scraper Material:
For the majority of applications, a solid UHMW or Acetron scraper will perform well to scrape the surface of the belt if
the above guidelines are followed. For inherently sticky products (e.g. icing, raw dough, ground meat, etc.), a softer tip
scraper can be used to create a wiper effect on the belt. For these applications a urethane material in the durometer
range of 82-86 Shore A is recommended. The material should be suitable for FDA/EU Direct Food Contact. Urethanes
are inherently flexible and will need to be secured to a stiffer element across the width of the conveyor to perform well.

Considerations for Sanitation
• Make sure the materials used to construct the scraper are compatible with common cleaning chemicals.
•
The fewer the parts in the construction of your scraper, the better.
•
Make sure any junctions are not collection points or niches for bacteria growth. If junctions exist, design the unit
so it can be easily taken apart and cleaned as necessary.
•
If possible, do not use threaded components in the construction of your scraper mount.
Best Practices when using a scraper with ThermoDrive belting
• Under high loads, ThermoDrive belting will deflect away from the scraper between drive sprockets, so minimizing
the space between sprockets (maximizing the number of sprockets) will enhance the performance of a scraper.
Using a full width sprocket or drum motor is ideal for both performance and sanitation.
•
The surface texture of the scraper can affect the release of product from the scraper. In general, the smoother the
surface, the more product will want to stick to the scraper (adhesion). Make sure to design with sanitation in mind.
•
When using ThermoLace, the width of your scraper should be reduced to avoid catching the edges of the
ThermoLace and account for belt clearance allowed in the conveyor system. The width of the scraper should be
the width of the belt (BW) minus one inch, centered to leave a half inch indent on both sides of the scraper.
a. Scraper Width = BW - 1 in (25.4 mm)

Design Guidelines: Troughed Conveyors
Unlike tensioned flat belting or rigid modular belting, ThermoDrive belts can be easily troughed for product control
without sacrificing the benefits of zero-tension, sprocket-driven operation. There are several possible configurations,
including: continuous, two-section, or three-section. Contact an Intralox representative for assistance with troughing
configurations.
Troughing conveyors should be designed using the principles and guidelines discussed in this manual while also
incorporating the guidelines listed below.
Use UHMW Containment Guides for lateral belt
containment (see page 8 for specific guidelines)
Carryway should transition from trough to flat for
a distance of 1.5x belt width (when a full depth
trough is required) before engaging with the
sprockets/rollers. This transition length is required
to minimize strain on the outer edges of the belt
and significantly reduce belt drag.

Temperature Factor for Belt Pull
Temperature
Temperature has an affect on the physical properties of thermoplastic materials. Generally, as the operating
temperature increases, the belt will weaken in strength, but become tougher and more impact resistant.
Conversely, in colder applications, belts can become stiffer and in some cases brittle. The temperature factor
curves show the effect of temperature on belt strength, and these graphs can be used in calculating the conveyor
belt analysis by hand. The Intralox Engineering Program calculates the temperature factor automatically, based
on the operating temperature of the application.

NSF: “The Public Health and Safety Company.” NSF
International is a non-profit association that helps
protect consumers by certifying products and writing
standards for food, water, and consumer goods.
NUB TOP™ (6.3 MM): A nub top belt that has an
overall thickness of 6.3 mm.
NUB TOP™ (7.8 MM): A nub top belt that has an
overall thickness of 7.8 mm.
O
OPEN AREA: The percentage of area in the plane
of a plastic belt that is unobstructed by plastic.
OUTER DIAMETER: The distance from the top
of a sprocket tooth to the top of the opposite tooth,
measured through the center line of the sprocket.
P
PREPARED ENDS: Belt ends are prepared and
ready to weld when received by the customer. No
measuring or cutting is required.
POLYURETHANE: A thermoplastic that is rigid and
smooth with a sealed surface. Polyurethane offers
superior impact resistance, while providing excellent
wear properties and elastic memory.
POSITIVE DRIVE: A term used to describe a
class of conveyor belt drive systems in which drive
power is consistently imparted to the conveyor belt
from the drive device strictly through the mechanical
engagement and interaction of the significant
meshing features of the belt and drive device.
POSITION LIMITER: A patented device used in
tensionless, positive-drive belting systems to ensure
proper continuous engagement of the belt and drive
sprocket by controlling the position of the belt during
the drive tooth hand-off process. Examples of this
device include scrapers, rollers, and shoes; it differs
from a belt snubber because it does not increase belt
wrap or belt tension at the drive sprocket location.
PRE-TENSION: The amount of tension initially
imposed on the conventional conveyor belt, creating
a tight wrap on the drive pulley so that drive power
can be effectively transmitted from the drive pulley
to the conveyor belting during ramping and running
without the occurrence of belt slippage.
Glossary
