Series Q-Single Row Ball Slewing Bearing-Internal gear

Slewing ring is also called "slewing ring" because its shape is similar to a plate. Its diameter is usually 0.2 ~ 5m. It is a large bearing that can bear axial and radial loads and overturning moments. The slewing bearing is composed of installation hole, inner gear ring or outer gear ring, isolation block, cage, lubricating oil hole and sealing device, so it can make the design structure of the host compact, simple guidance and easy maintenance.
