Control Resources
has now broadened its selection of ball screws to include a private-label
PRECISION ROLLED PRODUCTS from a trusted source. The hallmark of this
line is its lower cost (compared to ground screws) while still retaining
accuracy levels (C7) that meet or exceed the requirements of most applications.
 We
are stocking a wide range of lengths of these assemblies in 16mm (with
your choice of 5mm and 10mm pitch). All assemblies come with ends already
machined for the economical BK and BF mounts that we also supply. To
finish off your assembly, flexible motor couplings are also available
in several sizes.
Details &
Features of Rolled Ball Screw Assemblies
- Ball screws in
16mm diameter in C7 accuracy grade
- 5mm and 10mm
pitches available
- 10 standard sizes
of 16mm screws are available ranging from overall length of 350mm
(200mm travel) to 1550mm (1400mm travel).
- Ball nuts are
the "oversize ball" type rated as "anti-backlash."
Anti-backlash is defined as <0.015mm or <0.0006". Nuts
also come standard with flanges.
- Lead error not
to exceed +/- 0.050mm/300mm or 0.002"/12".
- Ball nuts supplied
with zerk-type grease fitting.
- End machining
has already been performed for the BK/FK (fixed) type mount on the
drive end and BF/FF (simple) type mount on the floating end of the
unit. Assemblies may be purchased with or without the mounts.
- We
attempt to keep all sizes in stock for immediate availability.
- Custom units
can be supplied in a reasonable time frame (usually 2 to 3 weeks).
