Product Overview
Robust Double Row Ball Slewing Bearing
This double row ball slewing ring bearing features a three-seat ring construction, designed to handle substantial axial forces and tipping moments. Utilizing two rows of steel balls, it offers exceptional stability and is engineered for demanding applications such as tower cranes, mobile cranes, and large-scale loading machinery. Its sturdy design is specifically optimized for working radii over medium ranges, ensuring reliable performance in heavy-duty industrial environments.
Technical Features
- Load Angles
- 90 degrees
- Design Considerations
- When radial force exceeds 1/10 of the axial force, the races require custom design.
