The cross cylindrical roller slewing bearing can carry axial load, tilting moment and radial load all at the same time. The design and application of the cross cylindrical roller slewing bearings are basically the same as those of the four-point contact ball slewing bearing, except that the rolling elements are substituted from balls into rollers and the contact way between the rolling elements and rings is changed from point contact into line contact. Those changes allow for the carrying capacity to be increased, but the wear and the friction moment load are also increased.

Tensun is the expert in high precision preloaded crossed roller bearings for precision applications like robotics, machine-tools, indexing and positioning tables, CNC tilting tables, milling heads, and many others.... Our tailor made design follows perfectly the specific requirements of the customers. 

Cross roller slew ring bearing is able to carry highest capacity in same size relatively.
