1. Point contact rolling working mode of slewing bearing

The point-contact rolling working mode is mainly used for four-point contact ball slewing bearings and cross-roller slewing bearings. This working principle has high requirements on the combination of point contact radial and axial force, and the quality of the steel ball, and the angle of the track should be uniform.

2. Surface contact rolling combined working mode of slewing bearing

The surface contact rolling combined working mode is mainly used for three-row roller slewing bearings. Its advantage is that the contact surface is large, the bearing force is uniform and the rolling is flexible.

3. Surface contact rolling and sliding combined working mode of slewing bearing

The surface contact rolling-slip combined working method is mainly used for turntable bearings. Now the new type of turntable bearing has a compact structure and high precision. Therefore, the surface contact rolling and sliding combined working method is the most suitable.

4. Rolling and sliding combined rolling working mode of slewing bearing

The main rolling-slip combined rolling working mode is mainly used for the ball-column combined slewing bearing. This principle has the advantages of small eccentricity and long service life, and has the advantages of the double structure of the roller and the ball.
