XR JR Series Crossed Roller Bearing

They provide a high degree of stiffness and low rotational torque within a minimal envelope. This design should be considered when a four-point contact ball bearing does not meet the operating performance requirements for torque and stiffness.

Applications:

XR Series bearings have been used successfully in applications requiring extra

stiffness with a low torque requirement including:

Radar

Military turrets

Machine tools

Tunnel boring machines
