XR Series Crossed Roller Bearing

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,NC rotary table
•Rotation part of Machine tools
•Inspection instrument,Medical equipment
• Aviation equipment,Military radar etc

Design Features of XR seriescross roller bearings

l The line contact of races and rollers can offer high rotation accuracy, high stability and high rigidity.

l The adjustment design of proload extend the bearing using life , increase the rigidity and reach the smallest runout.

l The nylon spacers has low inertia and small running torque.

l High rotation accuracy and high rigidity , and conserving material costs.l The steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself.
