What Is Four Point Contact Ball Bearing
- Oct 29, 2018 -

What is four point contact ball bearing?--The four point contact ball bearing are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions.The bearing are separable, i.e. the outer ring with ball and spacer assembly can be mounted separately from the inner ring.


The four point contact ball bearing makes it easy to simplify machine designs that have a combination of radial, thrust and moment loads because it can handle all three simultaneously. They are primarily used for slow to moderate-speed applications, or where oscillatory movement is predominant.


The four point contact ball bearing usually makes a second bearing unnecessary, which provides some very important benefits: savings

2.weight savings

3.cost savings

4.rigidity and accuracy

5.faster installation

6.less maintenance

7.integral mounting holes, gears, etc.

The Four point contact ball bearings are especially effective in applications in which the rotating element has a high ratio of diameter to axial length. Most have a large ratio of bore to section size: the larger this ratio, the thinner and more flexible are the individual races. Thin section bearing sizes range from 414 to 1094mm, and slewing ring bearings range from 200 to 5000mm O.D.It’s widely used for slewing conveyer,welding manipulator,light & medium duty crane,excavator,and other construction machinery.
