Cross Cylindrical Roller Slewing Bearings

Crossed cylindrical roller slewing bearing is composed of inner ring, outer ring, single row roller, cage (gasket) and sealing device. Crossed cylindrical roller slewing bearings can bear axial load, overturning moment and radial load at the same time. The design and application of the cross roller slewing ring are basically the same as the design and application of the four-point contact ball slewing ring. The difference is that the rolling element is replaced from the ball to the roller, and the contact method between the rolling element and the ring is changed. . Point contact becomes line contact. These changes allow for an increase in load carrying capacity, but wear and friction moment loads also increase.
