Here you find the whole range: from a standard ball screw with an axial clearance of max. 0,05 mm up to a reduced clearance or a pre-tensioned ball screw.
Pre-tensioned ball screws are available optionally: pre-tensioned with ball selection or pre-tensioned with double-nut units with a grounded distance ring.

The NEFF ball screw range conforms to DIN 69051 and to the NEFF standard.

Ball screw drives are available standard end machining or with customer-specific end machining.
Thanks to the low rolling friction and the suppressed breakaway torque a high mechanical efficiency < 98 % is realized and the required drive power is reduced.
Based on the continual development of the ball track profiles and the ball nut deflection systems, the NEFF Ball screws stand for exceptional high quality and life time.
