Single Row Four Point Contact Ball Slewing Bearing（Q series）——Internal gear

Structural characteristics, performance, and scope of application

The single-row four-point contact ball type slewing ring consists of two races. It is compact and light in weight. The steel ball is in contact with the arc track at four points and can withstand axial force, radial force and tipping moment. Construction machinery such as rotary conveyors, welding operators, small and medium-sized cranes and excavators are available.

Note:
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 watch is the maximum circumferential force, and the rated circumferential force is 1/2.
