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. 

Four-point contact bearings can be manufactured in accordance with ABEC precision grades and in larger sizes. In applications involving oscillatory motion with limited angles of rotation, when the runout is zero for much of the rotation, an ABEC 1 bearing can sometimes be used instead of an ABEC 3 or 5. In such cases, the critical requirement (axial runout or radial runout) should be specified to meet ABEC standards. Noncritical areas can be left up to the bearing manufacturer.

Four point contact ball Slewing bearing is widely used in construction and energy industry. UIPI manufactures large diameter ball and roller slewing bearing utilized in many applications such as :
