Three Row Cylindrical Roller Slewing Bearings

Three-row cylindrical roller slewing bearings are mainly composed of an inner ring, outer ring, three-row rollers, cage (spacer block), sealing device, etc. This slewing bearing design is suitable for most large-scale occasions with axial load and tilting moment, enormous radial load, or lower requirements for the frictional moment. Three-row cylindrical roller slewing bearings can simultaneously bear axial, tilting, and radial loads. Compared with the cylindrical cross roller slewing bearing, the load of each roller is reduced. Compared with double row roller slewing bearings, point contact becomes line contact, and the contact stress is reduced.
