STAR – Precision Ball Screw Assemblies
Product Overview
As simple as it is to describe
the elementary function of a
precision ball screw assembly,
in practice you are faced with
variety of types and applications.
Affordable system design is now
easier then ever:
New products have made the
catalogue grow in size.
On the following pages you will find
the various elements for you to
choose from, complete with order
specifications and examples.
A further new development is the
WINKGT calculation software
for designing and calculating
precision ball screw assemblies.
Written to run under the Windows
NT operating system, it is available
on CD-ROM for you to perform your
own calculations.
For over 20 years, Precision
Ball Screw Assemblies have
been a core product group
within the STAR range.
The related standards
(DIN 69 051 and ISO 3408) are
fully supported by Rexroth
STAR. For every STAR nut with
flange in this catalog you will
therefore find a corresponding
design with DIN mounting
dimensions.
STAR – Precision Ball Screw Assemblies provide technical designers
with diverse solutions for positioning and transport tasks:
– complete ball screw assemblies
with precision-rolled or ground
thread screws combined with any
of the available single or double
nuts
– precision-rolled screws of optional length, with soft-annealed
ends and ground-thread ECO
screws in grid lengths for end
machining by the customer
Alternatively, you can arrange for
Rexroth STAR to produce a design
calculation on your behalf. To do so,
– single nuts supplied on a
simply complete and return the
mounting tube; all single nuts in
inquiry form, ! see “Inquiry /
the version with reduced
Order Form”, on page 103.
backlash can be easily mounted
by the customer. In addition, the
adjustable-preload single nut
allows the customer to perform
preload adjustment in-house.
Precision-rolled screws are manufactured independently of customers
orders. Our large world-wide stocks
guarantee a fast response. Availability is one advantage, low prices
another.
To perform particularly demanding
positioning tasks we have developed a measuring system for
integration in the rails of ball and
roller rail systems (Catalog
R.82 350). The linear measuring
system in the rail then replaces the
positioning information in the ball
screw. This way we are able to
achieve a maximum of flexibility in
design and a maximum of precision
in operation. Each nut is manufactured with the same technology,
enabling it to be used in the
high-precision range too.
Nuts are available ex
stock from a large
cataloged range
covering different
mounting dimensions
and technical details.

bearings

Definition of a precision ball
screw assembly
DIN 69 051, Part 1 defines a ball
screw as follows:
An assembly comprising a ball
screw shaft and a ball nut which is
capable of converting rotary motion
into linear motion vice versa. The
rolling elements of the assembly are
balls.
It is used to convert a rotary movement into a linear movement or vice
versa.

Nut Housing MGS
Nut housings MGS are designed for
FEM-E-S, FDM-E-S and SEM-E-S.
In addition to bolting, the housings should
be locked in place by positive means
(e.g. two pins with a diameter equal to
that of the screws).
We recommend using screws with a
strength class of 8.8.

We have a solution to prevent problems
arising from out of big end bearing
diameters (e.g. visible thread grooves or
axial contact faces which are too small for
the locating bearing). Please ask.

Area of application
The STAR – Ground-Thread Screw is the
solution for high-precision applications.
Production
N.B.:
The conventional method of production for
screws is to grind the ball track.
The part numbers listed in the table apply
for a linear meter of screw without end
machining. Screws with customer-specific
end machining and a mounted nut are
issued with their own ID numbers.
As a rule, STAR screws are manufactured
to order complete with end machining.
Screws of class P3 and P1 are supplied as
standard with a lead test report.

delivery at extremely short notice, e.g. for
repairs, as samples or for pre-series. These
“ECO Screws“ can be end-machined as

STAR – Precision Ball Screw Assemblies
Pillow Block Unit SEA-L
Floating bearing with deepGroove ball bearing to DIN 625
The pillow block unit consists of:
– precision pillow block housing with
reference edges on two sides
– deep-groove ball bearing to
DIN 625... .2RS
– retaining ring to DIN 471
– O-ring to DIN 3771
All parts are supplied unmounted.
Purpose of the O-ring stopper
The floating bearing must be able to move
in axial direction in order to compensate
changes of screw length caused by thermal
expansion.
The O-ring prevents the bearing’s outer
ring turning as well (clearance in the bore).

STAR – Precision Ball Screw Assemblies
General
DIN 69 051 Part 1 defines a
ball screw as follows:
Advantages over the Acme
screw drive
– The mechanical efficiency of an Acme
screw drive is a maximum 50%,
whereas a ball screw can reach a
mechanical efficiency of up to 98%
– Higher life expectancy due to negligible
wear during operation
– Less drive power required
– No stick-slip effect
– More precise positioning
– Higher travel speed
– Less heat-up
Due to their high mechanical efficiency,
ball screws are in principle not self-locking.
Safety information
We recommend that a safety nut be
installed for particularly critical applications in vertical set-ups. Please ask.
05
90
Efficiency (%)
An assembly comprising a ball screw shaft
and a ball nut and which is capable of
converting rotary motion into linear motion
and vice versa.
The rolling elements of the assembly are
balls.

Selection criteria for ball
screws
The following factors should be considered
when selecting the ball screw for a given
application:
– degree of accuracy required (lead
deviation)
– in-service load conditions
– service life
– critical speed
– buckling load
– rigidity / permissible clearance or
desired preload
– charateristic speed
N.B.:
Radial and eccentric forces relative to the
screw must be avoided as they have a
negative effect on the life and proper
function of the ball screw.
Where special conditions of operation are
involved, please ask.
The following points should be taken into
consideration when selecting a ball screw
assembly that is to be both cost-efficient
and optimally designed:
– The lead is a decisive factor for the
load-carrying capacity (depending on
the maximum possible ball diameter)
and the drive moment.
– The calculation of the service life should
be based on average loads and average
speeds, not on maximum values.
– In order for us to provide you with a
customized solution, installation
drawings or sketches of the nut
environment should be enclosed with
your inquiry.

RE 83 301/12.99
Load-carrying capacities and
service life
Critical speed and buckling load
Sealing
Critical speed and buckling load
We calculate load-carrying capacities and
service life in accordance with DIN 69 051,
Part 4 and ISO 3408 - 4 (P5).
The critical speed and buckling load can be
checked using the corresponding charts.
Ball screws are precision assemblies that
require protection against contamination.
Flat protective covers and bellows type
dust boots are particularly suitable for this
purpose.
Basic static load rating C0
! See “Design Calculation“
on page 96 and 97
The static load rating is an axial, concentrically acting force that induces a permanent
deformation of 0.0001 x the ball diameter
between the ball and the ball raceway.
Characteristic speed d0 · n
Basic dynamic load rating C
The dynamic load rating is an axial,
concentrically acting force of constant
magnitude and direction under which a
representative sample of identical ball
screws can achieve a nominal life of one
million revolutions.
Service life
The nominal life is expressed by the
number of revolutions (or number of
operating hours at constant speed) that
will be attained or exceeded by 90% of a
representative sample of identical ball
screws before the first signs of material
fatigue become evident. The nominal life is
designated as L or Ln, depending on
whether it is specified in revolutions or
hours.
For precise calculations see formula 12 15
As there are many applications in which
these methods do not provide sufficient
protection, we have developed a wipertype seal which, due to the extremely low
friction between the lip edges and the
screw, ensures an optimal sealing effect
without noticeably reducing the high
efficiency of the assembly.
STAR ball screws can be operated at very
high speeds due to their internal ball
recirculation system. Characteristic speeds
of up to 150 000 are possiblw. Please ask.
We have therefore included these seals as
standard features of our ball screw
assemblies. At the customer’s request,
these seals can be omitted or special seals
used in their place.
d0 . n ≤ 100 000
d0
= Nominal diameter (mm)
n
= speed (min-1)
Material, hardness
Our standard ball screw assemblies are
made of high-quality, heat-treatable steel,
carbon chrome alloy steels or casehardened steels. The screw and nut raceways have a minimum Rockwell hardness
of HRC 58. Ball screw assemblies made of
corrosion-resistant steel (DIN 17230,
EN 10088) are also available upon
request. Unless otherwise specified, the
screw ends are not hardened.
Permissible operating temperatures
Ball screws are suitable for continuous
operation at temperatures up to 80°C with
temporary peaks of 100°C (measurements
taken on the outer shell of the nut).
Short strokes
In the chart the minimum required stroke
(travel) for a 10% lower load rating is
shown as a function of the number of
turns and lead of the nut. Hence the most
favorable range lies above each curve. It
can help to arrange for occasional longer
strokes, which are performed with
simultaneous relubrication as “lubricating
strokes“.
Short stroke limit (load rating reduced by less than 10%)
400
Stroke (travel) [mm]
During a short stroke the ball does not
make a real turn. It is impossible therefore
for an adequate lubricating film to form.
The results can be premature wear.

STAR – Precision Ball Screw Assemblies
Preload and Rigidity
Nut System Preload
Axial deflection
In addition to single nuts with reduced
backlash, Rexroth STAR supplies preloaded
or adjustable-preload nut systems.
Preloaded single nut
Double nut
Single nuts can be preloaded to 2% or 5%
of the basic dynamic load rating by means
of optimized ball size selection.
Tensioning two nuts against each other
eliminates the inherent backlash of the ball
screw, increases rigidity and thus improves
positioning accuracy.
As excessive preload can cause a reduction
in service life, we recommend that it not
be more than 1/3 of the average operating
load. Depending on the application we
will preload the nut system to 7% or 10%
of the basic dynamic load rating.
Single nut
without preload
Adjustable-preload
nut systems
Axial load
The rigidity of these three types of STAR
nut systems is approximately the same.
This is because the adjustable-preload
single nut and the preloaded single nut
have a much more compact design and are
thus only half as long as a double nut
system. The screw is far less rigid than the
nut unit (for details see “Overall axial
rigidity ...“).
Adjustable-preload single nut
The adjustable-preload single nut allows
cost-efficient design techniques to be
implemented in a large number of
applications. The radial clearance and
preload are adjusted radially via a slot
approx. 0.1 mm wide ! see “Mounting“
on page 90.
Depending on the application we will
preload the nut system to 2% or 5% of
the basic dynamic load rating. The
maximum preload equals approx. 5% of
the basic dynamic load rating.

RE 83 301/12.99
Overall Rigidity
The rigidity of a ball screw is also influenced by all adjoining parts such as
bearings, housing bores, nut housings etc.
The overall axial rigidity Rtot is comprised
of the componentrigidity of the bearing
RaL, the screw Rs and the nut Rnu and is
calculated according to the formular:

Please note that in most cases the rigidity
RS of the screw will be signifi-cantly lower
than the rigidity Rnu of the nut unit. In an
assembly with a diameter of 40 x 10, for
example, the rigidity Rnu of the nut unit is
2 to 3 times higher than the rigidity RS of
a screw with a length of 500 mm.

Mounting
Nut mounting, general
Mounting steps
– preloaded single nut
– double nut
The nut is to be mounted as follows:
These models are supplied with
premounted nut units. The nut unit and
screw may not be disassembled. Should
this become necessary for any reason,
please ask.
Remove the rubber ring from one end of
the mounting arbor.
Measurement of the dynamic drag torque
for SEM-E-C and SEM-E-S..
Using the adjusting screw, reduce the
clearance of the nut mounted on the
screw until the corresponding dynamic
drag torque Tpr0 specified in the table
! page 87, has been attained (ball
screw lightly oiled).
– single nut with reduced backlash
– adjustable preload single nut
The nut unit may only be mounted using a
mounting arbor. The outer diameter of the
arbor should be approx. 0.1 mm smaller
than the root diameter of the screw. In
most cases, the transport arbor on which
the nuts are delivered may be used to
mount the nut. The end of the screw
thread must be chamfered in order to
prevent damage to the seal and the
internal components of the nut unit.
– Setting the radial clearance or
preload of adjustable-preload
single nuts
Check this torque along the entire length
of the thread; if the torque deviates from
the value specified in the table at any
point along the thread, adjust accordingly.
Push the mounting arbor with nut until it
engages with the end of the thread.
The arbor must make contact with axial
clearance.
Once the torque has been properly
adjusted, the centering diameter D1 must
correspond to the values specified in the
table ! page 87. Cover the head of the
screw with a protective cap.

Proceed in reverse order when removing
the nut from the screw. Take particular
care not to damage the nut, screw or
internal components, as this could result in
the premature failure of the ball screw
assembly.

Inserting the wiper-type seal
Installation in the Machine
Condition as delivered
Position the nut on the screw as illustrated
in the diagram. Insert the wiper so that its
projection is in the recess and press it in
until it snaps into the groove. While
turning the nut on the screw, watch the
wiper lip carefully and straighten it if
necessary by applying pressure to the end
surface. Ensure that the lip is not damaged.
It is not normally necessary to remove the
preservative coating before installation.
STAR – Ball Screws are normally delivered
with an initial supply of grease type Klüber
Microlube GB 0 NLGI 0. Relubrication with
grease or oil is thus possible in principle,
but you will need to check that the
lubricant used is compatible with the initial
supply. The ball screws can also be
supplied with only a preservative coating if
preferred.
5 - 10 mm
Storage
Ball screw assemblies are high-quality
systems that must be treated with due
care. In order to prevent damage and
contamination, the elements should not be
removed from the protective wrapping
until immediately before installation. Once
they have been removed from the packaging, they must be set down on V-shaped
cradles.
RE 83 301/12.99
– If the ball screw is contaminated it
must first be cleaned (see “Cleaning”)
and reoiled.
– Push the nut unit into the mounting
bore, taking care to avoid any impacts
or misalignment.
– Tighten the mounting screws using a
torque wrench if necessary. See table
for the tightening torque that corresponds to the screw strength class.

Important:
The selected lubricant must be in the nut
before the machine is started.
Cleaning
Various cleaning agents can be used to
degrease and wash the assembly:
– aqueous cleaning agents
– organic cleaning agents
Important:
Do not use trichloroethylene!
Immediately after cleaning, thoroughly dry
all parts, then apply a preservative coating
or anti-corrosion oil. In all cases, take care
to observe the appropriate legal regulations (environmental protection, health
and safety at work, etc.) as well as the
specifications for the cleaning agent (e.g.
handling).

STAR – Precision Ball Screw Assemblies
Lubrication
Standard lubrication practices for ball
bearings also apply to ball screws.
Lubricant loss is, however, greater than
that of ball bearings due to the axial
motion between the screw and the nut.
Oil lubrication
The influence of the temperature on the
performance of the ball screw is very
significant, as the thermal expansion of
the ball screw interferes with the positioning accuracy of the assembly.
One of the advantages of oil lubrication
over grease lubrication is therefore the
minimized heat build-up of the ball screw,
particularly at high speeds.
As a rule, commercially available mineral
base oils used for ball bearings are
suitable. The necessary viscosity depends
on the speed, temperature and load
conditions of the respective application
(see DIN 51501, 51517, 51519 and GfT
Worksheet 3).
Oils ranging from ISO VG 68 to approx.
ISO VG 460 are used in practice. The high
viscosity grades (e.g. ISO VG 460) should
be preferred in general and particularly for
slow running screws. A maximum
relubrication interval of up to 10 operating
hours can be attained with small quantities from the table along side.

Grease lubrication
The advantage of grease lubrication is that
the ball screw can run long distances on
one supply of grease. As a result, a
lubricating system is not required in many
cases. The amount of grease used should
fill the nuts to approximately half of their
capacity.
All commercially available ball bearing
lubricating greases may be used. Read the
lubricant manufacturer’s specifications
carefully! Never use greases with solid
lubricant components
(e.g. graphite or MoS2).
Greases in accordance with DIN 51825
K2K and, for higher loads, KP2K of NLGI
Class 2 according to DIN 51818 are
recommended for the longest possible
lubrication intervals. Tests have proven
that greases of NLGI Class 00 achieve only
about 50% of the running performance of
Class 2 greases at high loads.
The lubrication interval depends on many
factors such as the degree of contamination, operating temperature, load, etc. The
following values can thus serve only as a
guideline.

(fixed - supported)
The critical speed nk depends on the
diameter of the screw, the type of end
fixity and the free length ln. No allowance
may be made for guidance by a nut
without preload.
The operating speed should not reach
more than 80% of the critical speed.
According to the graph, the critical speed
is 1850 min-1.
The permissible operating speed is thus
1850 min-1 x 0.8 = 1480 min-1.
The maximum operating speed in our
calculation example of n4 = 1000 min-1 is
therefore below the permissible operating
speed.
The characteristic speed is to be taken into
account, ! see “General“ on page 79.

permissible axial load is 360 kN.
A permissible axial load on the screw of
360 kN : 2 = 180 kN is achieved when
applying the safety factor 2. This therefore lies above the maximum operating
load of F1 = 50 kN used in our
calculation example.
(unsupported) length lk. A safety factor of
g ≥ 2 should be taken into consideration
when determining the permissible axial
load.

Angular contact thrust ball bearings
and deep-groove ball bearings
Slotted nut NMA, NMZ
When mounting the angular contact thrust
ball bearings LGF and LGN, ensure that
the mounting forces are exerted only on
the bearing rings. Never apply mounting
forces via the antifriction bearing elements
or the seal rings! The two sections of the
inner raceway may not be separated during assembly or disassembly for any
reason!
The bearings are preloaded by tightening
the nuts.
Tighten the mounting screws for screwdown or flange-mounted bearings in crosswise sequence. The mounting screws may
be subjected only to tension amounting to
a maximum of 70% of their yielding point.
The screw-down (LGF) bearings have a
groove on the cylindrical surface of the
outer raceway for disassembly. The individual bearings of the bearing pair series
LGF-C... and LGN-C... are marked on the
cylindrical surfaces of the outer raceways
(see diagram). The markings reveal the
bearing sequence. The sealing rings should
face outward after proper.
In order to prevent settling phenomena,
we recommend first tightening the slotted
nut by twice the value of the tightening
torque MA and then easing the load. Only
then should the slotted nut be retightened
to the specified tightening torque MA.
The two set screws are then alternately
tightened using a hexagon socket wrench.
The components are disassembled in the
reverse order, i.e. the set screws are to be
removed before the slotted nut.
The slotted nuts can be used several times
when properly assembled and disassembled by competent personnel. The inner
raceways of the bearings are dimensioned
in such a way as to achieve a defined
bearing preload sufficient for most
applications when the slotted nut is
tightened (MA in accordance with
Dimension Table).

Lubrication of the end bearings
Bearings for ball screw assemblies are
lubricated with grease for a lifetime of
reliable service. It should be noted,
however, that grease lubrication does not
facilitate the dissipation of heat in the
bearings. The bearing temperature should
therefore not exceed 50°C, particularly in
machine tool applications. Angular contact
thrust bearings of the series LGF, LGN are
lubricated for life with grease KPE2K to
DIN 51825.

If the radial operating forces are not

Bearings for ball screw assemblies are also
able to accommodate tilting moments. As
a rule, the moments that usually occur due
to the weight and drive motion of the
screw do not need to be incorporated in
the calculation of the equivalent bearing

The bearing friction torque MRL is primarily
dependent on the bearing preload. The
influence of the operating load FaB is
insignificant as long as it does not exceed
the limits at which the bearings have zero
clearance. The bearing friction torque MRL
gspecified in the Dimension Tables applies
to the preload generated by means of the
slotted nut tightening torque RaL. The
bearing preload is selected so as to allow
it to remain effective even at high operating loads and ensure that the bearing has
zero clearance.
