Single-row four-point contact ball slewing bearing (HSW series)-external Gear
Structural characteristics, performance, scope of application
Single-row four-point contact ball slewing bearing consists of two races. It has a compact structure and light weight. The steel ball contacts the arc raceway at four points. It can simultaneously bear axial force, radial force and tipping moment. Construction machinery such as rotary conveyors, welding operators, small and medium-sized cranes and excavators can be selected.
1. n1 is the number of lubricating oil holes, evenly distributed: oil cup M10 × 1 JB / T7940.1-TB7940.2.
2. The mounting hole n-Φ can be changed to a screw hole; the tooth width b can be changed to H-h.
3. The circumferential force of the gear in the table is the maximum circumferential force, and the rated circumferential force is 1/2.
4. The coefficients of displacement in the table are all external gear design.
