The BS series uses 3mm to 16mm diameter ground ball screw with 3mm to 6mm lead variants. This is our most compact nut design. Mounting is via external keyway offering the smallest nut diameter and length possible. Backlash can be eliminated. Using a compact cylindrical single nut, axial play can be eliminated using over sized balls. The BS series has a  with repeatable accuracy of  C3 (zerobacklash) or C5 ( 5 micron maximum backlash)

For more performance data, screw and nut dimensions please see our catalogue.
