Weight: 93.1-4000kg
3. Feature: 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.
4. Material:50Mn/42CrMo/S48C/42CrMo4/16Mn

Features
The Single-row Four-point Contact Ball Slewing Bearing consists of two seating rings. It is characterized by compact structure, light weight and four-point contact between the steel balls and the arc raceway. It can bear axial force, radial force and overturning moment simultaneously. It is applicable to the engineering machinery, such as slewing conveyors, welding manipulators, small-and-medium cranes, and excavators.

Note:
1.n1 is the number of oil holes, equally spaced, with oil cup M10×1 JB/T7940.1-TB7940.2
2.The mounting hole n-Φ can be replaced by the threaded hole; the tooth width b can be changed to H-h
3.The tangential force of internal gear is the maximum tangential force; the rating tangential force is half of the maximum tangential force
4.The displacement coefficient of internal tooth follows the design of external teeth.
