Ball Screw is designed for higher speeds.

August 31, 2004

With feed ratings to 200 m/min and permissible DN values to 210,000, Type SBK utilizes Caged Technology, which employs synthetic resin cage with curvature that cradles each ball and separates it from next. This helps decrease noise and dust generation, while overall design eliminates ball re-circulation tubes. For ball screw contamination protection, QZ Lubricator and Wiper Rings are available as options. Type SBK sizes range from 3636-5050. Read More

Ball Screw utilizes caged technology.

September 12, 2002

Type SBK ball screw achieves maximum feeds of 120 m/min and permissible DN value of 160,000. Utilization of Caged Technology prevents ball-to-ball contact and associated friction, and allows balls to smoothly circulate in tangential line. Cage also acts as reservoir for lubricants, eliminating need for external lubricating system. Optional wiper ring acts as barrier to prevent foreign matter and swarf from entering nut interior.
