Luoyang Xinneng Bearing four-point contact ball slewing bearing (slewing bearing) can bear axial load, overturning moment and radial load at the same time.

Luoyang Xinneng Bearing four-point contact ball slewing bearing (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.

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

Luoyang Xinneng four-point contact ball slewing bearing inner ring and outer ring 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.

Luoyang Xinneng Bearing four-point contact ball slewing bearing (slewing bearing) usually has a cage (or spacer block), only when the load is large, the full-complement ball structure is adopted, and the full-complement ball four-point contact ball bearing has a large bearing capacity. However, the friction resistance is large, and the friction can easily cause 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.

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