Four-point contact ball slewing ring bearings are mainly composed of inner ring, outer ring, single row of steel balls, cage (or isolation block), sealing device and other parts of the combination.
Four-point contact ball slewing ring bearings inner ring, outer ring has integral and split structure. Integral ring of steel is relatively strong, split type adjustment is convenient, split type structure in the product before the factory has been utilized to bolt the two split ring coupling together.
Four-point contact ball slewing ring bearings in general have a cage (or isolation block), only in the load is relatively large when the choice of fully loaded ball structure, fully loaded ball four-point contact ball bearing capacity, but the friction resistance, friction is also easy to cause the surface layer of the steel ball to produce scratches.
Four point contact ball slewing bearing/slewing bearing basic structure: have no tooth type, external tooth type and internal tooth type, and flange type, has a relatively high static load capacity.
