Shuangzheng single row four point contact ball slewing rings composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four points; it can bear the axial force, radial force and the tilting moment at the same time. Shuangzheng Single-row four point contact ball ring has the features of compact in design, and light in weight. The balls roll on the circular race at four points, so it can undertake the axial force, radial force and tipping moment at the same time.
This series of four point contact ball bearings are suitable in many engineering machinery, such as rotary conveyor welding operation machine, small cranes, small and medium-sized excavators,slewing conveyor, welding manipulator, light and medium duty crane, and other construction machinery.
Three types of this kind of single row four point contact ball slewing bearing:
A. Without gear bearing (non tooth)
B. External gear bearing (external tooth)
C. Internal gear bearing (internal tooth)
Slewing ring, also known as turntable bearing is suitable to coordinate control various types of loading including axial, radial and tilting moment loads with a large diameter.
Slewing ring is available in various sizes and type like a gearless, internal, or external gear configuration; lubrication holes and grease seals.
Shuangzheng could offer a cross rolling element or with either a double o rthree row internal configuration if required. All of the products will be well-arranged for transportation.
Combined, all of these variables can be offered by Shuangzheng to their customer as a compact and economical arrangement for their basic and complex slewing rings and turntable bearings needs alike.
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.
