Four-point contact ball slewing bearing can bear axial load, overturning moment and radial load at the same time.

Four-point contact ball slewing bearing can bear axial load, overturning moment and radial load at the same time. Under the combined action of axial load and overturning moment, almost all steel balls are involved in bearing the load. When subjected to pure axial load, the steel ball and the inner and outer ring raceways are in single-point contact. When the radial load exceeds a certain value, the steel ball and the inner and outer ring raceways have two points of contact respectively, at this time, the wear and friction torque will increase. In order to cope with different combinations of axial force, overturning moment and radial force generated under various working conditions, the contact angle can be adjusted accordingly.

The four-point contact ball slewing bearing is mainly composed of inner ring, outer ring, single row of steel balls, cage (or isolation block), sealing device and other parts.

The inner ring and outer ring of the four-point contact ball slewing bearing have integral and split structures. The rigidity of the integral ferrule is relatively strong, and the split type is easy to adjust. The split type structure has been connected with two split rings by bolts before the product leaves the factory.

The four-point contact ball slewing bearing usually has a cage (or spacer block), only when the load is large, the full-complement ball structure is used. The full-complement ball four-point contact ball bearing has a large bearing capacity, but has large friction resistance and easy friction Causes scratches on the surface of the steel ball.

According to the installation needs, the installation holes can be designed as straight holes, countersunk holes, threaded blind holes, threaded through holes, etc.

Four-point contact ball slewing bearing is suitable for occasions where axial load is the main factor, there is overturning moment and the friction resistance is small. During installation, the support is required to have sufficient radial rigidity.
