Four-point Contact Ball Slewing Ring Bearing

Contact Now

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.Four-point contact 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 1" to 40" and slewing ring bearings range from 4" to 178" O.D.Bearings require a minimum amount of space and can carry either pure axial loading or combined loading. For heavy industrial requirements, 4 points contact ball style of ring can be designed as a large slewing ring bearing with bolted down races and internal or external integral gearing. Four-point contact ball bearing can handle all three simultaneously, which makes it easy to simplify machine designs that have a combination of radial, thrust and moment loads.
