STAR – Precision Ball Screw Assemblies
Product Overview
For nearly 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), though
relatively young by comparison, are fully supported by STAR:
for every STAR nut with flange in this catalog you will find a
corresponding design with DIN mounting dimensions.
STAR ball screws provide technical designers with diverse solutions for positioning and transport tasks. Moreover, affordable
system design is made easy with
- precision-rolled screws
- preloaded single nuts
- adjustable-preload single nuts (patented)
Affordable precision-rolled screws replace ground-thread
screws in a wide range of application areas.
Preloaded single nuts with optimized ball size selection or
patented adjustable-preload single nuts are much more cost
efficient than conventional double-nut systems.
Single STAR nut units and off-the-shelf precision-rolled screws
guarantee short delivery periods for complete ball screw
assemblies.
STAR offers the following product range:
4
-
complete ball screw assemblies
ground-thread or precision-rolled screws combined with any
of the available single or double nuts, with end machining
-
precision-rolled screws, optional length,
with soft-annealed ends
for end machining by customer
-
single nuts supplied on mounting arbor
All single nuts in the version with backlash can be
easily mounted by the customer. In addition, the adjustablepreload single nut allows the customer to perform preload
adjustment in-house.
Available from stock
Particularly smooth motion due to the
tangential lift-off of the balls from the
raceway within a single, fully enclosed
ball circuit in the nut
short nut length
Effective sealing
No protruding parts,
nut is easily mounted
High load-carrying capacity
due to large number of recirculating balls
Smooth outer shell, consistently

General
DIN 69 051 Part 1 defines
a ball screw as follows:
An assembly comprising a ball screw
shaft and ball nut, which is capable of
converting rotary motion to linear motion
Advantages over the
Acme screw drive
• The mechanical efficiency of an Acme
screw drive is a maximum of 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
and vice versa. The rolling elements of
the assembly are balls.
• no stick-slip effect
• more precise positioning
• higher travel speed
• less heat-up
Due to their high mechanical
efficiency, ball screws in principle
are not self-locking and can
backdrive.

Design Notes
Selection Criteria
The following factors should be considered in the selection of the ball screw
required for a given application:
-
degree of accuracy required
(lead deviation)
-
permissible clearance or desired
preload
-
in-service load conditions
-
service life
-
critical speed
-
buckling load
-
rigidity
• in order for us to provide you with a
customized solution, installation
drawings or sketches of the nut and
screw environment should be
enclosed with your inquiry;
• no special bearings are required for
ball screws; bearings used for conventional screws are suitable. At least
one bearing must be able to take up
axial thrust forces. Where high rigidity
is required, we recommend the use
of combined radial and thrust
bearings;
• the end machining will be done
according to customer specifications.
The diameter of the bearing seats
should correspond to the recommended dimensions for end bearings.
A drawing should be enclosed with
the inquiry. Star standard end machining options with the matching
bearings are also available.
The following points should be taken
into consideration when selecting a ball
screw assembly that is to be both costefficient 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;
• 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.
• the calculation of the service life
should be based on average loads
and average speeds, not on maximum values;
In order to help us find the ball screw
that best suits your application, please
complete the inquiry/order form at the
back of this catalog.
Please mark any questions that you are
unable to answer as well as those
values that you would like us to define.

Material, Hardness
Our standard ball screw assemblies are
made of high-quality, heat-treatable
steel, carbon chrome alloy steels or
case-hardened 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.
Sealing
Ball screws are precision assemblies
that require protection against contamination. Flat protective covers and
bellows type dust boots are particularly
suitable for this purpose. As there are
many applications in which these
methods do not provide sufficient protection, we have developed a wiper-type
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. We have
therefore included these seals as standard features of our ball screw assemblies. At the request of the customer,
these seals can also be omitted.
Permissible Operating
Temperatures
Ball screws are suitable for continuous
operation at temperatures of -20° to
+100°C
Load-Carrying Capacities
and Service Life
In accordance with DIN 69 051 Part 4
and ISO 3408 - 4 (P5).
Basic static load rating C0
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.
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 Lh, depending on
whether it is specified in revolutions or
hours.
Critical Speed and Buckling
Load
The critical speed and buckling load can
be checked using the corresponding
charts. For precise calculations see
formula 12
CharacteristicSpeed d0·n
STAR ball screws can be operated at
very high speeds due to their internal ball
recirculation system. The recommended
limit is:

Result and selection
The ball screw can now be selected from the Dimension Tables:
e.g. ball screw, size 63 x 10 R x 6-6, with preloaded single nut with flange,
basic dynamic load rating C = 88 800 N, part no. 1512-6-4003.

L ≈ 1042 · 106 revolutions

The life of the selected ball screw
assembly is thus greater than the
required service life of 24,000 hours
(including operating hours). A smaller
ball screw could therefore be selected.

Critical Speed
The critical speed 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. The characteristic speed is to
be taken into account: (see Page 19)
= 63 mm
= 2.4 m
(fixed - supported)
According to the graph, the critical
speed is 1850 rpm.
The permissible operating speed is thus
1850 rpm x 0.8 = 1480 rpm.
The maximum operating speed in our
calculation example of n4 = 1000 rpm
is therefore below the permissible
operating speed.

Permissible axial load on
screw (buckling load)
The permissible axial load on the screw
depends on the diameter of the screw,
the type of end fixity and the effective
free (unsupported) length lk.
A safety factor of γ ≥ 2 should be taken
into consideration when determining the
permissible axial load.

A permissible axial load on the screw of

applying the safety factor 2. This therefore lies above the maximum operating

Preload and Rigidity
In addition to single nuts with reduced
backlash, STAR supplies preloaded or
adjustable-preload nut systems.
The graph illustrates that preloaded nut
systems have a significantly lower spring
deflection than a single nut without
preload.
Axial deflection
Nut System Preload
single nut
without preload
Adjustable-preload
nut systems
Axial load
Double nut
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. If the customer
does not specify a certain preload, we
will preload the nut system with approx.
10% of the basic dynamic load rating.
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 also: Mounting
Instructions).
The maximum preload is approx. 5%
of the basic dynamic load rating. The
dynamic drag torque corresponds to
that of a double-nut system with a
preload of approx. 13% of the basic
dynamic load rating.
Preloaded single nut
Single nuts can be preloaded with
approx. 5% of the basic dynamic load
rating by means of optimized ball size
selection.
The rigidity of these three types of STAR nut systems is approximately the same, as 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 (please also note the information given under “Overall Rigidity”).
24
Overall Rigidity
The rigidity of a ball screw is also influenced
by all adjoining parts such as bearings,
housing bores, nut housings etc.
Overall axial rigidity Rtot of the
ball screw
The overall axial rigidity is comprised of
the component rigidity of the bearing
RaL, the screw RS and the nut unit Rnu
and is calculated according to the
following formula:
R = axial rigidity
(N/µm)
RaL = see Dimension Tables /
16
Rigidity of the bearing RaL
The rigidity of the bearings corresponds
to the values found in the bearing
manufacturer’s catalog. The rigidity of
our bearing assemblies can be found
in the tables.
Rigidity of the screw RS
The rigidity of the screw depends on the
type of bearing used.
Please note that in most cases the
rigidity RS of the screw will be significantly 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.

Nut Mounting
- adjustable-preload single nut
- double nut
- single nut with reduced backlash
- adjustable preload single nut
These models are supplied with premounted nut units. The nut unit and
screw may not be disassembled.
Please consult us first, should this become necessary for any reason.
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.
The nut is to be mounted as follows:
Remove the rubber ring from one end of
the mounting arbor.
Push the mounting arbor with nut until it
engages with the end of the thread.
The arbor must make contact without
axial clearance.
Carefully turn the nut unit onto the
thread, applying only light axial
pressure.
Do not remove the mounting arbor until
the entire nut unit is seated on the
screw thread.
Proceed in the 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.
26
Mounting instructions are supplied as
standard along with every unit.
Setting the radial clearance
or preload of adjustablepreload single nuts
Using the adjusting bolt, reduce the
clearance of the nut mounted on the
screw until the corresponding dynamic
drag torque Tpr0 specified in the table has
been attained (ball screw lightly oiled).

Check this torque along the entire length
of the thread; if the torque exceeds the
value specified in the table at any point
along the thread, adjust accordingly.

Once the torque has been properly
adjusted, the centering diameter D 1 must
correspond to the values specified in the
table. Cover the head of the bolt with a
protective cap.

Inserting the wiper-type seal
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.
5 - 10 mm
Be careful not to run the nut past the end of the screw thread.
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.
Installation in the Machine
It is not normally necessary to remove
the preservative coating before
installation.
- 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 bolts using a
torque wrench if necessary. See table
for the tightening torque that corresponds to the bolt strength class.
Tolerances
28
Observe the correct tolerances when
installing the nut (see “Nut Housings”).
Once they have been removed from the
packaging, they must be set down on
V-shaped cradles.

The standard lubrication practices that
apply to antifriction bearings also apply
to ball screws. Either oil or grease may
be used as a lubricant.
Lubricant loss is, however, greater than
that of antifriction bearings due to the
axial motion between the screw and the
nut. In most cases, the initial supply
of grease will not last for the entire
service life of the assembly. Graphite
and MoS2 additives must not be used.
Oil lubrication
The influence of the temperature on the
performance of the ball screw is very
significant, as thermal expansion interferes with the positioning accuracy of
the assembly. One of the advantages of
oil lubrication is the minimized heat
build-up of the ball screw, particularly
at high speeds. As a rule, commercially
available petroleum base oils used for
antifriction 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).
Grease lubrication
The advantage of grease lubrication is
that the ball screw can run for 500 to
1000 hours 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 pockets to approximately half of
their capacity. All commercially available
antifriction-bearing lubricating greases
may be used. Do not mix different
varieties together. Ball screws subjected
to normal loads should be lubricated
with a KP2K antifriction bearing lubricating grease as specified in DIN 51825.
Read the lubricant manufacturer specifications carefully!
Cleaning
Various cleaning agents can be used to
degrease and wash the assembly:
- aqueous cleaning agents
- organic cleaning agents
Lubrication
Before the ball screw is put into
operation, a lubricant must be
applied to the nut via the lube hole.
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).

Precision-Rolled Screws
The Star precision-rolled screw
presents an affordable alternative
to the conventional ground-thread
screw.
A particular advantage is the possibility
of stocking various sizes and tolerance
grades, as the rolled screws can be
manufactured in advance independently
of any customer order. This ensures
supply at short notice and at an
attractive price.
Star supplies precision-rolled screws
with ends machined to specifications
and the nuts ready-mounted. Alternatively, they can be supplied without end
machining or with annealed ends. In
these cases, the nuts are supplied separately on a mounting arbor.
(see also “End Machining Details” and
“Mounting and Lubrication Instructions”)
Precision-rolled Star screws comply
with the acceptance conditions and
tolerance grades defined for T type
screws according to DIN 69 051,
Part 3, or ISO 3408-3.
44
Star screws attain considerably better
values than those required by the DIN
standard; the permissible actual travel
deviation being halved in the precisionrolled screw. In addition, the very linear
lead characteristic of the precision-rolled
screw greatly facilitates travel compensation in machine control systems.
If the screw ends are to be machined by
the customer, the most suitable solution
is to use the screw with a single nut with
backlash or with Star’s patented
adjustable-preload single nut.
If Star is to supply screws with readymachined ends, it is also possible to use
a single nut preloaded by optimum ball
size selection or a double nut.
For particularly demanding applications,
customers may, upon request, receive
a test report recording the total lead
deviation. This allows type T5 screws to
be classified according to tolerance
grade P5.
(see “Acceptance Conditions and
Tolerance Grades”)

End Bearings, Design Calculations
Star supplies complete drive systems
including the required end bearings.
Design calculations for these are performed according to the formulas usually
applied in the antifriction bearing industry.
Resulting and equivalent
bearing loads
The angular contact thrust ball bearings
are preloaded. The chart shows the
resulting axial bearing load Fa as a
function of preload and axial operating
load FaB. If the system is primarily subject to axial operating loads, then F = Fa.
If the radial operating forces are not insignificant, the equivalent bearing loads
are calculated according to formula 20 .
F = X · Fr + Y · Fa

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 load.

Average speed and
average bearing load
If the bearing is subject to varying axial
loads over time, the average axial
bearing load can be calculated using
formula 21 .
If the speed varies, apply formula 22 .
In these formulas, the qi values represent
the discrete time steps in %.
If the radial load Frm varies, calculate the
average radial load in the same manner.

F0 = maximum static load
(N)
The static load safety factor of machine tools
should not be lower than 4.
Friction
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 specified
in the Dimension Tables applies to the
preload generated by means of the slotted nut tightening torque MA. The preloaded bearing has the rigidity 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.
26
The bearing friction torque MRL is
measured at a speed of n = 5 rpm.
The friction power loss NRL of the
bearing can be calculated using the
formula 26 .
The various operating speeds ni must be
incorporated in the heat balance as a
function of their time fractions qi.

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.

series ZKLN, ZKLF are lubricated for life
with grease KPE2K to DIN 51825.
This eliminates all drawbacks associated
with in-service lubrication such as overgreasing or the use of an unsuitable type
of grease.

Mounting Instructions
Mounting
Angular contact thrust ball bearings
and deep-groove ball bearings
Slotted nut
When mounting angular contact thrust
ball bearings Series ZKLN and ZKLF,
ensure that the mounting forces are only
exerted 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.
Tighten mounting screws for screwdown or flange-mounted bearings in
crosswise sequence.
The mounting screws may only be
subject to tension amounting to a
maximum of 70% of their yielding point.
The screw-down (ZKLF) bearings have a
groove on the cylindrical surface of the
outer raceway for disassembly. The
individual bearings of the bearing pair
series ZKLN...2AP and ZKLF...2AP 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 assembly.
The bearings are preloaded by tightening
the nuts ZM.
In order to prevent settling phenomena,
we recommend first tightening the
slotted nut by 2 times 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 counter set screws are then
alternately tightened using a hexagon
socket wrench.
The components are disassembled in
the reverse order, i.e., the counter set
screws are to be removed before the
slotted nut.
The slotted nuts can be reused 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).

Nut Housings for FEM-E-S and SEM-E-S
For ball screw assemblies with
flanged nuts and adjustable-preload
single nuts
(not suitable for DIN versions)
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 bolt).
We recommend using bolts with a
strength class of 8.8. See “Mounting”
for tightening torques.
Material:
Spheroidal graphite cast iron
