XR Series Crossed Tapered Roller Bearings

XR Series crossed tapered roller bearing, this particular designed single bearing, has two tapered roller bearings functions and offers the highest level of rotational accuracy and rigidity. This bearing can withstand high radial, axial, and moment loads. Crossed tapered roller bearings’ applications can be simplified; it helps reduce assembly time. The bearing is preloaded. It promotes the machine’s accuracy because the shaft thermal expansion minimizes bearings with preload.

XR Series Crossed Tapered Bearing characteristics:

1. High precision: precision at P4, P4, P2.

2. High rigidity: these series bearings are with preload.

3. High load capacity: can support radial, axial, and tilting loads.

4. High speed: rollers roll in the raceway, so the limited rate of crossed taper roller bearings is higher than that of crossed cylindrical roller bearings.

5. Low friction: the frictional torque of crossed taper roller bearings is much lower than that of crossed cylindrical roller bearings.

Application of XR Series Crossed Tapered Bearing:

This makes the XR Series crossed tapered roller bearing suited to applications where space is limited, or the lowest possible center of gravity of a rotating mass is required and high speed. And withstand high overturning moments, for example, accuracy machine tools circular division rotary table, vertical and horizontal boring machine, vertical grinder, rotary surface grinding machine, vertical lathe, large-scale gear hobbing machine, turret, large telescope (radio telescope and optical telescope), rotation camera, industry robot.
