NSK support bearings are factory lubricated with special long-life grease formulations and designed to extend the life of NSK ball screws. No re-lubrication is required, trimming installation time and maintenance costs. Each bearing is preloaded for maximum axial rigidity. Preloading also prevents ball skid and decreases runout.
Support units offer universally-ground Single Universal (SU) bearings that can be combined to replace any mounting configuration (face-to-face, back-to-back or tandem), thus reducing your inventory needs dramatically. Inch and metric sizes are available to suit your requirements.
