Available on 4mm to 14mm diameter rolled ball screw stock  with 1mm to 6mm lead variants.

This is our most compact nut design. Mounting is via external keyway offering the smallest nut diameter and length possible. This range of precision rolled ball screws operate just below the accuracy grades of ground ball screw assemblies. By using precision ground ball nuts and then pairing them with precision cold rolled ball screws, can provide lead accuracies of less than 52 microns of error 300mm.  Abssac can supply outside diameters in the range from 4mm to 14mm with a range of leads per diameter. Due to the rolling process taking considerably less time than the ground ball screw manufacturing operation, the delivery time is also significantly reduced.

Abssac can supply pre-machined, ready to fit assemblies from the BSR series, which not only eliminates your potential scrap rates, but also ensures that the assemblies  supplied are certified with the accuracy tolerances. For more performance data, aswell as further screw and nut dimensions please see our catalogue. 2D and 3D drawings available on request.
