couplings are available in 24 sizes from a minimum torque rating of 3.5 in–lbs to a
maximum torque rating of 170,004 in–lbs and a bore range of .125 inches to 7
inches. Lovejoy’s standard bore program covers AGMA, SAE, and DIN bore/
keyway and spline bore combinations.
The Lovejoy Jaw Type coupling is available in a variety of metal hub and insert
materials. Hubs are offered in sintered metal, aluminum, bronze, steel, stainless
steel, and ductile iron.
L COUPLING
LC COUPLING
AL COUPLING
L Type
This coupling offers standard shaft-to-shaft connection for general industrial duty
applications. Standard L type coupling hub materials are either sintered iron (L035 L150) or cast iron (L190 - L276).
LC Type
This is the basic L coupling, except the insert is a snap wrap elastomer with
retaining collar. Designed for easy elastomer replacement without disturbing the
hubs, this coupling type is suited for applications over 1750 RPM.
RRS COUPLING
AL Type
The aluminum construction means this coupling is light weight with low overhung
load and low inertia. The AL type also offers excellent resistance to atmospheric
conditions, so it is perfect for corrosive environment applications.
RRS Type
The center “drop out” section of this coupling provides proper shaft separation
while also allowing easy elastomer installation without disturbing the hubs or
requiring realignment of shafts. Designed for the pump industry, it accommodates
American and European industry standard pump/motor shaft separations. The
drop out spacer is made of glass reinforced plastic, cast iron or aluminum.
SW COUPLING
SW Type
This coupling is the standard L Type with a snap wrap elastomer with retaining
ring. It is well suited for standard shaft-to-shaft connection in general industrial
purpose applications under 1750 RPM.
C & H COUPLINGS
C & H Types
These couplings provide standard shaft-to-shaft connection for medium (C)
and heavy (H) duty range applications. The standard C coupling hub is made
of cast iron, while the H is constructed of ductile iron.

Jaw Type
Overview
Elastomers-in-Compression
JW
Lovejoy offers four types of elastomer designs to allow for additional
flexibility in addressing specific application requirements. One piece designs
are used in the “L” and “AL” models (referred to as spiders) and multiple
part “load cushions” are used in the “C” and “H” model couplings. The load
cushions are in sets of 6 to 14 pieces depending on coupling size.
Solid Center Spider
The solid center design is the most commonly used in general power
transmission applications when the shafts of the driver and driven can be
kept separate by a standard gap.
Open Center Spider
The open center spider design allows the shafts of the driver and driven to
be positioned within a short distance. Open center spiders offer shaft
positioning flexibility but have a lower maximum RPM capability. (1750 RPM
max. for NBR, 3600 RPM max. for Urethane/Hytrel.)
Cushions
The cushion design is available exclusively for the Lovejoy Types C and H
jaw couplings. The load cushions are held in place radially by a steel collar
which is attached to one of the hubs. This design allows for easy installation
and removal of the load cushions. The cushion design has the same
engineering purpose as the spider designs but is more effective in the
heavy duty applications that Types C and H couplings address.
Snap Wrap Flexible Spider
The snap wrap flexible spider design allows the spider section of the
coupling to be easily installed or removed without disturbing the coupling
hubs. This design also allows for close shaft separations all the way up to
the hubs maximum bore, which is not possible with open center spiders.
Maximum RPM is 1750 with retaining ring, but if used in LC Type (with
collar) the normal RPM rating of the coupling size applies. This style is
available in NBR and Urethane only, and in limited sizes.
NOTE:
Complete technical data for the new Jaw In-Shear elastomer is contained in
the next section of this catalog, labeled “JIS” on the page tabs.
Spider Materials
SOX (NBR) Rubber
Nitrile Butadiene (Buna N) Rubber, a highly flexible insert material that is oil
resistant, is our standard elastomer. It resembles natural rubber in resilience
and elasticity, and operates effectively in temperature ranges of -40° to
+ 212° F (-40° to +100°C). (Also applies to SXB Cushions.)
Urethane
Urethane has 1.5 times greater torque capability than NBR and offers good
resistance to oil and chemicals. However, this material provides less
dampening effect and operates at a temperature range of -30° to +160° F
(-34° to +71°C).
Hytrel
Hytrel is a flexible elastomer designed for high torque and high temperature
operations. Hytrel can operate in temperatures of -60° to +250° F
(-51° to +121°C) and has an excellent resistance to oil and chemicals. It
is best used in continuous load applications rather than cyclic or on/off
service.
Bronze
Bronze is a rigid, porous, oil-impregnated metal insert exclusively for low
speed (max. 250 RPM) applications requiring high torque capabilities.
Bronze performance is not affected by water, oil, dirt, or extreme temperatures — operates in temperatures of -40° to +450° F (-40° to +232° C).

Jaw Type
Selection Process
JW
Jaw Type Coupling Selection Process
The selection process for determining the proper jaw coupling size and
elastomer requires using the charts shown on the following pages. There
are three components to be selected, two hubs and one elastomer. When
the shaft size of the driver and driven of the application are of the same
diameter, the hubs selected will be the same. When shaft diameters differ,
hubs selected will differ accordingly.
Information necessary before a coupling can be selected:
n HP (or KW) and RPM or Torque of driver
n Shaft sizes of driver and driven equipment and
corresponding keyways
n Application description
n Environmental conditions (i.e. extreme temperature,
corrosive conditions, space limitations)
List of Charts provided for Selection:
Chart 1—Application Service Factors (pg. JW-6)
Chart 2—Spider Performance Data (pg. JW-7)
Chart 3—Coupling Nominal Rated Torque (pg. JW-7 or JW-20)
Formulas:
(HP x 63025)
Nominal Torque =
in-lb =
RPM
Nm =
(KW x 9550)
RPM
Design Torque = Nominal Torque x Application Service Factor
Steps In Selecting A Jaw Coupling
Step 1: Determine the Nominal Torque of your application by using the
following formula:
(HP x 63025)
Nominal Torque =
in-lb =
RPM
Nm =
(KW x 9550)
RPM
Step 2: Using the Application Service Factors Chart 1 (pg. JW-6) select
the service factor which best corresponds to your application.
Step 3: Calculate the Design Torque of your application by multiplying the
Nominal Torque calculated in Step 1 by the Application Service
Factor determined in Step 2.
Design Torque = Nominal Torque x Application Service Factor
Step 4: Using the Spider Performance Data Chart 2 (pg. JW-7),
select the elastomer material which best corresponds to your
application.
Step 5: Using the Coupling Nominal Rated Torque Chart 3 (pg. JW-7),
locate the appropriate elastomer material column for the
elastomer selected in Step 4.
Scan down this column to the first entry where the Torque Value
in the appropriate column is greater than or equal to the Design
Torque calculated in Step 3.
Once this value is located, refer to the corresponding coupling
size in the first column of the Coupling Nominal Rated Torque
Chart 3 (pg. JW-7).
JW-4
Refer to the maximum RPM value (pg. JW-20) for this elastomer
torque capability to ensure that the application requirements are
met. If the requirement is not satisfied at this point, another type of
coupling may be required for the application. Please consult our
Lovejoy application engineers.
Step 6: Compare the application driver/driven shaft sizes to the maximum
bore size available on the coupling selected. If coupling bore size is
not large enough for the shaft diameter, select the next largest
coupling that will accommodate the driver/driven shaft diameters.
Refer to Chart 3 (pg. JW-7).
Step 7: Using the Item (UPC) Number Selection charts (pgs. JW-9 and
JW-10), find the appropriate Bore and Keyway sizes required and
locate the Lovejoy Item (UPC) number.
Jaw Type
Selection Process
A coupling is needed to connect a 20 HP standard electric motor rated at
1800 RPM to a rotary pump. The shaft size of the electric motor (driver) is
2.0 inches and the pump (driven) is 1.75 inches. There are no special
environmental conditions and the general operating temperature is normal
room temperature of 72° F. Less than 1° of misalignment is expected.
Step 1: Determine the Nominal Torque:
Nominal Torque = (HP x 63025)
RPM
= (20 x 63025)
1800
= 700.28 in-lb
Step 2: Using the Application Service Factor Chart 1 (pg. JW-6), select
the service factor which best corresponds to your application.
The Application Service Factor for an electric motor with standard
torque driving a rotary pump is 1.25. The value of 1.25 is found
under the application category Pumps, Rotary, column: Electric
Motor w/Standard Torque in Chart 1.
Step 3: Calculate the Design Torque of your application:
Design Torque = Nominal Torque x Application Service Factor
= 700.28 x 1.25
= 875.35 in-lb
Step 4: Using the Elastomer Performance Data Chart 2 (pg. JW-7),
select the elastomer material which best corresponds to your
application. Since there are no special environmental conditions,
the operating temperature is 72°F and less than 1° of angular
misalignment is required, the NBR elastomer material is selected.
JW
Selection Example
Therefore, the proper coupling size for this application is a
Lovejoy L190 with an NBR elastomer.
Step 7: Using the Item (UPC) number Selection charts, locate the
appropriate Lovejoy Item (UPC) numbers. The L Type
Coupling Elastomer chart (pg. JW-8), and the L Type Coupling
Inch Hubs chart (pg. JW-10), provides easy reference to the
Lovejoy Item (UPC) numbers.
Locate the L Type Couplings Elastomer chart (pg. JW-8).
The elastomer is selected by scanning down the type column
and locating the NBR (Solid) entry. Read across to the L190
column and locate the Lovejoy Item (UPC) number of 12274.
This number should be prefixed with the Lovejoy Item (UPC)
number of 685144.
Locate the L Type Coupling Inch Hubs selection chart (pg. JW-10).
The first bore size to be located is for the 2 inch shaft on the
electric motor. Scan down the Bore/Keyway column to the 2 inch
bore entry. Read across to the L190 column to locate the Lovejoy
Item (UPC) number of 12303. This number should be prefixed
with the Lovejoy Item (UPC) number of 685144.
The second bore size to be located is for the 1.75 inch shaft on
the pump. Scan down the Bore/Keyway column to the 13/4 inch
bore entry. Read across to the L190 column to locate the Lovejoy
Item (UPC) number of 12299. This number should be prefixed
with the Lovejoy Item (UPC) number of 685144.
Step 5: Using the Coupling Nominal Rated Torque Chart 3 (pg. JW-7),
the NBR elastomer column is used to determine the proper
coupling size. Scanning down the NBR column, the first entry to
accommodate the Design Torque value of 875.35 in-lb is the size
L150 with a nominal torque rating of 1,240 in-lb. Referring to
page JW-20, the maximum RPM of 1800 on the electric motor of
the application does not exceed the 5000 RPM maximum allowed
for the L150 size coupling with an NBR elastomer.
Step 6: Compare the application driver/driven shaft size to the maximum
bore available in the coupling selected (pg. JW-7). The electric
motor (driver) of this application has a shaft size of 2.0 inches
and the pump (driven) has a shaft size of 1.75 inches. The L150
coupling has a maximum bore less than the driver shaft size.
Continuing down the Maximum Bore column, in Chart 3
(pg. JW-7), the L190 size is found to have a maximum bore
size of 2.125 and is able to accommodate the driver/driven
shaft sizes.

L Type Coupling
The L Type sizes range from L035 to L276. Ordering requires selecting
Item (UPC) numbers for two standard L hubs and one standard open or
solid center elastomer (spider).
SW Type Coupling
The SW Type sizes range from L090 to L190. Ordering requires selecting
Item (UPC) numbers for two standard L hubs and one snap wrap spider.
For both L and SW Type couplings, select hubs from the Standard Bore
and Keyway chart (pgs. JW-9 and JW-10). Max. RPM for SW + Ring is
1750 RPM. LC coupling types must be used for speeds above 1750 RPM.
The LC Type coupling uses a snap wrap spider with a collar instead of a
retaining ring.
Jaw In-Shear Coupling
Ordering requires selecting item numbers for two standard hubs, one
In-Shear elastomer and one In-Shear ring. See pages JIS-1 through JIS-4.
