XZWD 4 point contact ball Slewing Ring turntable bearing with External Gear for Truck Mounted Crane

XZWD 4 point contact ball Slewing Ring turntable bearing with External Gear for Truck Mounted Crane. Slewing bearings have special structure and can carry combined radial, axial, and tilting moment loads simultaneously; they are widely used in the slewing arrangement of lift, metallurgy, mining, construction, harbor and wind turbine machinery, and so forth. Maximizing the carrying capacity of the slewing bearing is one pursuing goal for the bearing designer, Xuzhou Wanda slewing bearing has designed a series slewing bearing, such Single Row Four Point Contact Ball Slewing Bearing,Single Row Crossed Roller Slewing Bearing,Double Row Ball Slewing Bearing,Three Row Roller Slewing Bearing.

Single row 4-point contact ball Slewing ring is available in various sizes and type like a gearless, internal, or external gear configuration; lubrication holes and grease seals.

Description:

The single row four point contact ball bearings are suitable to high speed and high precision rotary, and can bear combined load. The single row four point contact ball bearing includes inside and outside rings. Single-row four point contact ball ring is compact and light. With balls roll on the circular race at four points, it can control the axial force, radial force and tipping moment at the same time. The axial load bearing capacity increases with more contact angles, and single row four point contact ball bearing would rotate at a high speed.
