We can produce six series of slewing bearings with diameters ranging from 200mm to 5, 050mm.

Six series of slewing bearings:
1) Single-row four point contact ball series
2) Three-row roller series
3) Single-row crossed roller series
4) Double-row ball series
5) Roller and ball combination series
6) Light type profile bearings

CHARACTERISTIC OF STRUCTURE, PERFORMANCE AND APPLICATION of Single-row four point contact ball series

The single-row four point contact ball slewing bearing is composed of 2 seat-rings. It features compact in design, light in weight, the balls contact with the circular raceway at four points, via which the axial force, radial force and resultant moment may be born simultaneusely. It maybe used for slewing conveyers, welding operating consoles, light, medium duty cranes, excavators and engineering machinery.
