The Single Row Four Point Contact Ball Slewing Bearing is composed of 2 seat rings.It features compact in design,and light in weight.The balls contact with the circular race at four points,via which the axial force,radial force and resultant moment may be born simultaneously.
It may be used for slewing conveyer, welding arms and positioners,light,medium duty cranes,excavators and other engineering machines.

Product available including: Single and Double Row Ball, Three Row Roller, Cross Roller Sealed and Unsealed Internal Geared, External Geared and Non-Geared Clearance or Preloaded

■ four point contact bearings
– these slewing rings without preload are robust and proven under very demanding operation; they place only slight demands on the flatness and perpendicularity of the adjacent construction

– they are suitable for applications with low requirements for accuracy and rigidity of the bearing arrangement, for example in simple metalworking machines, wind power equipment and construction machinery

World Famous Global Hot Sale XZWD Four Point Contact Ball Turntable Slewing Ring Bearing

Turntable and Slewing Ring bearings utilize one to three rows of balls or rollers in order to provide smooth rotation even under extremely large loads. In addition to radial and axial loads, these bearings are able to support large moments in situations when loads are cantilevered away from the bearing’s central axis.

Turntables and Slewing Rings are offered in both metric and inch sizes with the ability to customize the mounting interfaces to suite your application. What differentiates Slewing Rings from Turntables is the inclusion of gear teeth on either the inner or outer rings.

We focus and control every production detail,Only for the delivery of good products to customers.

The material of the slewing bearing are generally high alloy-structural steels,such as 42CrMo,50Mn.

The material of rolling body is GCr15 and it is purchased from domestic suppliers with highest quality.
