Four-point Contact Ball Slewing Bearings
Four-point Contact Ball Slewing Bearings
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.
