 XR/JXR Cross taper roller bearings

Bearing features:
1.     High precision: precision at P4, P2.
2.     High rigidity: these series bearings are with preload.
3.     High load capacity: can support radial load, axial load, and tilting load.
4.     High speed: rollers do pure rolling, so the limited speed 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 scope:
Crossed taper roller bearings can be widely applied in high speed vertical lathe, high precision working table, vertical boring machine, and main axis of grinding machine etc.

 In order to make it easy for calculation, the load rating noted in the above file is based on working 3000h at the speed of 500r/m, i.e. L10 life. While the limited bearing speed is depended on bearing dimension and the real load, and the speed is possible to be under 500r/m.
