Slewing bearings are also called rotary table bearings or slewing bearings, an oversized bearing that can withstand the comprehensive load, or a combination bearing with high efficiency and high bearing capacity, which can bear large axial load, radial load and overturning moment at the same time. Its working mode and principle are similar to bearings, its principle is very simple: the way to move the object has sliding rolling, reduce friction resistance. Slewing bearing consists of two rings, a group of rolling body and cage, which is a universal mechanical foundation. There are different working modes according to the actual use and design structure.
