Cylindrical Bearings

  Slewing bearing usually consists of a wall bearing rings of the two lead, cage, and guide roller assemblies form a ring, usually separable bearings. Such bearing installation and removal more convenient, especially when required, the outer ring and the shaft and the housing are interference fit more shows its advantages. These bearings are generally used only for radial load, only the inner and outer rings are single row bearings with ribs can withstand axial load is small or large intermittent axial load. Same size and shape of the deep groove ball bearings, such bearings have greater radial load capacity, from a structural point of view, but also for high-speed rotation.
DF roller and the raceway using crown-shaped design and it could be revised to eliminate the edge stress and improve bearing life.
The DF wall design has some inclination angle, so the bearing axial loads to be bigger than the conventional design.
No outer wall or the inner wall cylindrical roller bearings
