Slewing bearing slewing bearing is a kind of to be able to afford the larger axial load, radial load and overturning moment
Combined load of the special structure of the large bearing. In general, the turntable bearing its mounting holes, run
Oil hole and sealing devices, can satisfy various working conditions of the different needs of various host;
On the other hand, the turntable bearing itself has the advantages of compact structure, convenient, easy installation guide is rotated and easy maintenance etc.
Characteristics, are widely used in lifting the transport machinery, mining machinery, construction machinery, port machinery and other large back
Turning device. We produce the turntable bearings according to different structures can be divided into four point contact ball slewing axis
Bearing, double-row angular contact ball slewing bearing, crossed cylindrical roller slewing bearing and three row cylindrical roller slewing axis
The different structures of the above types of bearings according to whether they take and tooth
distribution is divided again for no gear, external gear, internal gear with different structures.
