STAR – Precision Ball Screw Assemblies

Area of application
The STAR – Ground-Thread Screw is the
solution for high-precision applications.
Ground-thread “ECO-Screws“
We keep stocks of screws in standard sizes
and popular lengths in case you need
delivery at extremely short notice, e.g. for
repairs, as samples or for pre-series. These
“ECO Screws“ can be end-machined as
required at short notice.
The number of standard sizes kept in stock
is increased in accordance with inquiries.
Please ask.
Please note that with very large end
bearing diameters (bigger than d 2 ) the
thread grooves may remain partly visible.
Production
The conventional method of production for
screws is to grind the ball track.
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.
