Super Precision Bearings

A series of angular contact ball bearings that has been designed specifically for swiveling spindle heads used in machine tools, such as machining centers and multi-tasking machine tools, and is suitable for high precision processing. The Robust Slim series of highly accurate, low profile, angular contact ball bearings offer high moment stiffness and low torque rotation.

Features

  1. Ball bearings achieve high running accuracy and low torque rotation.
  2. High moment stiffness on a par with crossed roller bearings.
  3. Exclusive design of the thin cross-section profile is thinner than that of a standard angular contact ball bearing.

Robust Slim™ Series

   
   

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.

Features

  1. The highly rigid series for machine tool applications has been designed specifically to provide large axial rigidity and precise rotation with lower starting torque.
  2. The highly rigid series is available with a lubricant seal for machine tool applications.
  3. The high load capacity series for electric injection molding machines offers enhanced service life through the use of optimally designed ball diameter and contact angle for a higher load rating.
