Single Row Four Point Contact Ball Slewing Bearing
Contact NowSingle Row Four Point Contact Ball Slewing Bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported .
Single Row Four Point Contact Ball Slewing Bearings contact angle is usually 35°. If there is only a radial load, each steel ball contacts the raceway at four points. If there is only a unidirectional axial load, each steel ball contacts the raceway at two points. It can bear axial loads in two directions as well as a certain eccentric load, i.e. torque. Such kind of bearing has features and properties of both single-row and double-row angular contact ball bearings. If it is used in a high-speed scenario, two-point contact must be ensured for its normal working.
Single Row Four Point Contact Ball Slewing Bearing are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported (→ Load ratio). The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.
Both inner ring halves of four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with an SKF cylindrical roller bearing (fig. 1). In addition, these recesses can be used to facilitate dismounting.
