Rings For Excavator Single Row Four Point Contact Ball Slewing Ring Bearings

A 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.

Today, more than ever, design engineers are challenged to simplify designs in order to reduce cost and weight. In many applications, four-point contact ball bearings—which do the job of multiple bearings by handling radial, thrust and moment loads simultaneously—are an ideal solution.

XZWD Slewing Bearings has manufactured thin section and slewing ring bearings in four-point contact configurations for many years, and specializes in helping designers turn ideas into engineered solutions.
