Slewing Bearings

Introduction to our Slewing Bearings
1. Slewing bearing is firstly applied in excavators and cranes, and gradually, it is used in other machines. It can carry not only thrust load, but also moment load and radial load.
2. As a professional slewing bearing manufacturer in China, we can provide many kinds of slewing bearings, such as four point contact ball slewing bearings with internal gear, four point contact ball slewing bearings with external gear, four point contact ball slewing bearings with flange, triple row cylindrical roller combined slewing bearings, cross roller slewing bearings, and so on.
3. Our slewing bearings can be divided to different types.
3.1 According to their structure, there are sing row slewing bearings, double row slewing bearings and three row slewing bearings.
3.2 According to their conduction, there are slewing bearings with gear teeth on inner ring or outer ring and slewing bearings without gear teeth.
3.3 According to their installation, there are slewing bearings with flange on outer ring or inner ring and bolt hole, and slewing bearings without flange.
3.4 According to their leak tightness, there are slewing bearings with seal and slewing bearings without seal.
4. These slewing bearings are easy to assemble and are of high accuracy. They are widely used in heavy lifting equipment, wind-power generating equipment, and shielded equipment, etc.
