New Products: Compact Ball Screw

The SBK ball screw features feed rates 2.2 times faster than typical of conventional ball screws.

A recirculating ball structure makes the SBK suitable for high-speed operation at DN values of 130,000. In addition, a synthetic resin cage with special curvature cradles each ball and separates it from the next one. Spaces between the rolling elements retain grease and act as a lubrication system for long-term, maintenance-free operation. It also ensures smooth motion, because separating balls eliminates friction, minimizes torque fluctuation, and prevents noisy collisions between balls. The SBK is available with screw-shaft ODs ranging from 15 to 32 mm and nut diameters from 38 to 58 mm.
