XR JR Series Crossed Roller Bearing
Classification :
PRODUCT DETAILS
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
