XR series Crossed taper roller bearings

Machine tool precision bearings

Product Features

Cross tapered roller bearing contains two sets of races and rollers brought together at high angles with alternate rollers facing in opposite directions. The height of cross section is similar to single-row bearing for conserving space and saving bearing housing material.And the steep-angle,tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself.

Applications

  • Industrial Robotic arm, Reducer drive
  • Precision Turntable, CNC rotary table
  • Rotation part of Machine tools
