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.

Series Model No.
