Cross tapered roller bearing is a variation of cross cylindrical roller bearing. During working, its tapered rolling elements do pure rolling movement without relative sliding, hence the limit speed of this kind of bearing is far higher than that of cross cylindrical roller bearing, while the friction moment is lower.
BRS Cross tapered roller bearing features:
1. High precision (P4)
2. High rigidity (XR & JXR series cross tapered roller bearing is with preload)
3. High loading capacity. Take radia, axial & tilting loads.
4. Higher limit speed compared to cross cylindrical roller bearing
5. Lower friction moment compared with cross cylindrical roller bearing
Applications: High speed worktable, Vertical boring mills,Vertical grinding machines spindles and Other machine tools
