The single row four point contact ball slewing bearing is composed of two seat rings, which design in 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.

About Single Row Four Point Contact Ball Slewing Bearing Single row four point contact ball slewing rings are composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four points;

Four point contact ball slewing ring are widely used in various application fields, such as excavators, cranes, rotary tables & positioners, wind turbine, ladle turret furnace, ferris wheel, water treatment, slewing drive, forest machine, medical devices, mining equipment, packaging machine, radar,

Four-point contact ball slewing bearings is mainly made up of inside and outside rings.Single-row four point contact ball ring(https://www.slew-bearing.com/Four-Point-Contact-Ball-Bearing-pl560537.html)has the features of compact in design, and light in weight. The balls roll on the circular race at

A slewing bearing or slewing ring turntable is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slow-oscillating load.Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.As for

Slewing ring bearing is widely used in engineering ship, especially in ship crane for slow-turning under heavy load. In ship crane, slewing ring serves as a joint between the upper structure and the undercarriage, providing a means of 360-degree rotation. As the load situation for ship crane slewin
