The single row four point contact ball bearing is composed of two seat rings, which design is compact structure and light weight, steel ball contact with the circular raceway at four point, it can bear the axial force, radial force and the tilting moment at the same time.
It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator and other construction machinery. engineering machinery: auto crane, excavator, tower crane; mining machinery: bucket wheel machine; metallurgy industry: clay gun, ladle turret, slewing mechanism of furnace cover. Besides, it is also applied to harbor machinery, welding machine, wind power generating set, medical device (CT machine), etc.
Four point contact ball bearing is a fundamental mechanical part for the slewing motion of engineering machinery, mining machinery, building machinery and others. Four point contact ball bearing has functions of transmission of motion, load bearing and connection. Compared with the bearing, slewing bearing is in general applied to low speed and heavy duty.
