Structural characteristics, performance, and scope of application
The single-row four-point contact ball type slewing bearing consists of two races. It is compact in structure and light in weight. The steel ball is in contact with the arc track at four points. It can simultaneously support axial force, radial force and tilting moment. Conveyors, welding operators, small and medium-sized cranes and excavators can be used.
1. n1 is the number of lubricating oil holes, evenly distributed: oil cup M10×1 JB/T7940.1-JB/T7940.2
2. The mounting hole n-Φ can be changed to the screw hole; the tooth width b can be changed to H-h.
3. The circumferential force of the gear in the form is the maximum circumferential force, and the rated circumferential force is 1/2.
