Flange Slewing Bearing for Mining Equipments (VLA200844N)

Slewing ring is also called "slewing ring" because its shape is similar to a plate. Its diameter is usually 100-5000mm. 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.

Product Description

Slewing ring bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing ring bearings have their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions;On the other hand, slewing ring bearing itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.
Our Xuzhou Helin slewing ring bearings are usually used for low revolution while shaking and strained with an enormous axial force, moment and in some parts with radial force simultaneously.
