Ball Bearings: Specifiions and Selection Criteria for

Jul 30, 2015· Slewing ring or turntable bearings can accommodate axial, radial and moment loads. They are not mounted in a housing or on a shaft, but instead are mounted directly to a seating surface. The inner and outer rings are supplied with mounting holes. The inner ring, outer ring, or both may have integral gears.

How mounting can optimize slewing ring bearing performance

Aug 31, 2016· Without an adequate structure, bearing performance usually suffers — and often the performance of seals, pinions, gears, and bolts as well. A new white paper from Kaydon Bearings, an SKF brand, explains the importance of mounting structure integrity, rigidity and deflection, and why they should be considered early in the design process.
