■ 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

Our xuzhou wanda slewing bearing Product type:

1.Single Row Four Point Contact Ball Slewing Bearings.

2.Single Row Crossed Roller Slewing Bearings

3Double Row Ball Slewing Bearings

4.Three Row Roller Slewing Bearings

5.Thin Section Slewing bearings(Light type).

6.Thin Section Slewing Bearings (Flange type)

– these preloaded slewing rings can support higher loads than four point contact bearings. They have proved themselves particularly where bearings are subjected to high radial forces and moderate axial and tilting moment loads
– they are suitable for applications with uniform running free from stick-slip, low rotational resistance and high requirements for axial and radial runout accuracy and rigidity, for example in robots, handling systems and machine tools.

Note:

1. n1 is the nos of lubricating holes.Oil cup M10×1JB/T7940.1~JB/T7940.2.The Oil nipple’s location can be change according to the user’s application.

2. n-φcan change to tapped hole,the diameter of tapped hole is M,depth is 2M.

3. The tangential tooth force in the form is the max tooth force,the nominal tangential tooth force is 1/2 of the max one.

4. “K” is addendum reduction coefficient.

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.
