Single-row four-point contact ball slewing bearing (QW 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 lubricant holes, evenly distributed: oil cup M10 × 1 JB / T7940.1-JB / T7940.2
2. The mounting holes n-dn1 and n-dn2 can be replaced with screw holes; 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.
