There are four-point contact ball bearings with or without teeth, outer teeth and inner teeth, double row angular contact ball bearings, cross cylindrical roller bearings, cross tapered roller bearings and three row cylindrical roller combined bearings. Among them, four-point contact ball bearings have high static load capacity; cross cylindrical roller bearings have high dynamic load capacity; cross tapered roller bearings can make bearings have greater support rigidity and higher rotary accuracy through pre-interference.
Rotary disc bearings are widely used in cranes, excavation machinery, construction machinery, port machinery, marine machinery, high-precision radar machinery and missile launchers and other large rotary devices.
