Highly precise angular contact thrust ball bearings for precision ball screws have been designed specifically for each application. Lineup includes both a highly rigid series and high-capacity series for precision angular contact bearings.

Features of Ball Screw Support Bearing Units
The highly rigid series ball screw fixed end support bearing units for machine tool applications have been designed specifically to provide large axial rigidity and precise rotation with lower starting torque.

The highly rigid series ball screw support bearing installation units are available with a lubricant seal for machine tool applications.

The high load capacity series ball screw support bearing units for electric injection molding machines offer enhanced service life through the use of optimally designed ball diameter and contact angle for a higher load rating.
