STAR – Precision Ball Screw Assemblies

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.
Alternatively, you can arrange for
Rexroth STAR to produce a design
calculation on your behalf. To do so,
simply complete and return the
inquiry form, ! see “Inquiry /
Order Form”, on page 103.
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
– single nuts supplied on a
mounting tube; all single nuts in
the version with reduced
backlash can be easily mounted
by the customer. In addition, the
adjustable-preload single nut
allows the customer to perform
preload adjustment in-house.
– matching nut housings and end
bearings
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.
