Slewing bearings (also known as turntable bearings) are large bearings that can withstand axial, radial and overturning moments at the same time. They are known as the "joint of machines". They have a wide range of applications. The core areas include engineering machinery, lifting and transportation equipment, new energy equipment, medical machinery, ship and port machinery, light industrial machinery, etc., and have gradually expanded to high-end fields such as robots and aerospace equipment. ‌

The single-row four-point contact ball rotor bearing consists of two races, which are compact in structure and light in weight. The steel ball contacts four points of arc scrolling, and can withstand axial, radial and tilt torque at the same time. Swivel conveyor welding operation machine, small and medium-sized cranes, excavators and other construction machinery can be selected.
