Triple Row Roller Slewing Bearings

Three-row roller slewing bearings are mainly composed of 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, or with larger radial load, or with lower requirements for frictional moment. Three-row roller slewing bearings can simultaneously bear axial load, tilting moment and radial load. Compared with the cross cylindrical 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 also reduced.
