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.
