Slewing ring bearing mounting structures | Kaydon Bearings white papers
Mounting a slewing ring bearing in the proper structure is crucial to properly distributing bearing load and stress. Without an adequate structure, bearing performance is likely to suffer. So can the performance of the seals, pinions, gears, and bolts. Therefore, mounting should be considered very early in the design process.
slewing ring bearings | FV-Bearing
Slewing ring bearings. Slewing rings are generally large size ball or roller bearings with very high load carrying capacity for oscillating motions and slow rotary motions. The bearings are mainly mounted in a horizontal position and are used to support axial forces and large tilting moments. Radial loads only occur to a subordinate extent.
