The slewing bearing is a large bearing that can withstand the combined load and can withstand large axial, radial loads and overturning moments. The slewing bearing usually has a mounting hole, an internal gear or an external gear, lubricating oil holes and a sealing device, so that the design of the main body is compact, the guiding is simple, and the maintenance is easy. There are toothless slewing bearings, slewing bearing with external gear and slewing bearing with internal gear. Slewing bearings are widely used in large-scale rotary devices such as lifting machinery, mining machinery, construction machinery, port machinery, ship machinery, and high-precision radar machinery and missile launchers. At the same time, we can design, develop and produce various special structure slewing bearings according to the specific requirements of users. Read More

The external gear slewing bearing is a slewing bearing with external teeth. It is a new type of mechanical component. It consists of inner and outer rings, rolling elements and so on, and has external gears on the outside of the bearing. The slewing bearing with external gear is a large bearing capable of withstanding the combined load and can withstand large axial, radial loads and overturning moments at the same time. Read More

A slewing bearing or slewing ring is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill.
