Ball Screw (KGS)

Kugelgewindespindel KGS

Our standard range offers rolled ball screws. We also provide swirled or grounded ball screws.

When thread rolling, the thread profile is rolled by cold forming process. This treatment maintains a high firmness and surface quality. The Gothic pointed arch profile with a 45° contact angle and optimized osculation guarantees optimum running characteristics and high load factors, which is proofed by a high efficiency. The NEFF manufacturing process, beginning with tailored raw material, then rolling the thread and following inductive hardening and the final finish guarantees the constant high standard of our ball screws.

The ball screws in stock vary from Ø12 to Ø80 with threads up to 60mm.

The standard pitch variation of rolled ball screws is tolerance class T 7 (52µ/ 300mm). Because of the continuous process chain in the ball screw production, we are able to provide ball screws with accuracy of tolerance class T 3 (12µ/ 300mm).
