Four Point Single Row Slewing Ring Bearings Contact Ball Slewing Bearing External Gear
Slewing bearing is a bearing that can accommodate large axial load, radial load and overturning moment. Slewing bearings generally have installation holes, inner teeth, outside teeth, lubricants holes and sealing devices, which enable the main frame structural compact, guide reliable, and easy to maintain. Slewing bearings are widely used for lifting machinery, excavating machinery, construction machinery, engineering crane, port machinery and ship machinery, electricity equipment, as well as other larger rotary devices, such as high-precision radar and missile launchers.
Single row four point contact ball slewing bearing two seat, compact structure, light weight, and the ball arc raceway of four point contact, can bear axial force, radial force and overturning moment. Rotary conveyer, welding operation machine, small cranes and excavators and other engineering machinery can be used.
