About This Product

■Summary

Slewing bearings (slewing bearings, slewing rings, slewing seats) are used as bearings to support the swiveling parts of machines with various swiveling structures, such as construction machinery and equipment machinery.

■Structure of slewing bearing

-Single row ball type is the standard type of slewing bearing (slewing bearing, slewing ring, slewing seat), and is widely used because it is low in manufacturing cost and easy to handle. ・The internal structure is a 4-point contact type angular thrust ball bearing, which allows composite loads such as thrust load, radial load, and moment to be applied simultaneously. The inner and outer ring raceway surfaces consist of two circular arcs, and the balls are arranged in short rows. ・Since a large ball diameter can be used, the design structure is compact and has a large rated load.

Requests for vertical use (horizontal axis orientation) or high-speed rotation can be accommodated by changing to a cage-equipped model. In addition, recently, slewing bearings are increasingly being used in precision machinery such as medical machines such as C.T. scans and machine tools such as polishing machines.
