Slewing bearings are combination structure including non-gear, outside gear, internal gear and four-point contact ball bearings, double angular contact ball bearings, cross-cylindrical roller bearing and three rows cylindrical roller bearings and so on. In which, four-point contact ball bearings have higher static load capacity, while cross-cylindrical roller bearings have higher dynamic load capacity.

Slewing bearing widely used in lifting machinery, excavate machinery, construction machinery, port machinery, ships machinery, as well as precision radar launchers and large rotary devices such as missile launcher.
