(1) Single-row four point contact ball slewing bearing
Single row four-point contact ball slewing bearing consists of two races, and has compact structure, light weight and four-point contact arc raceway. It can withstand axial force, radial force and tilting moment at the same time. Rotary conveyor, welding manipulator, small and medium-sized crane, excavator and other construction machinery are optional.
Main structural features: The contact angle between ball and raceway is generally 45 degrees, so it can withstand axial force, radial force and overturning moment. It has large static load capacity, can rotate flexibly, and is the most widely used slewing bearing.
