Aug 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.
