BRS Cross tapered roller bearings XR/JXR series
The XR series consists of cross roller bearings, which provide a high degree of stiffness and low rotational torque within a minimal envelope. Consider this design when a four-point contact ball bearing does not meet the operating performance requirements for torque and stiffness. XR series roller bearings have been used successfully in applications requiring extra stiffness with a low torque requirement, including radar, military turrets, machine tools, and excavators.
