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.
