Interchange Series Kaydon Slewing Bearings
Xuzhou Xinda Slewing Bearing Co., Ltd is a specialized manufacturer and exporter of all kinds of slewing bearing for standard and non-standard application,which is specializing in producing,designing and R&D .
Slewing bearing can carry axial loads, tilting moment and radial loads all at the same time. Almost all steel balls will carry load under the combined action of axial load and tilting moment load. Steel balls are in contact with the raceway of outer ring and inner on a single-point, respectively when carrying pure axial load. When radial loads exceed a certain value there would be two points respectively for the contacting balls within the outer and inner raceway. Meanwhile, wear and friction moment would be in large order to overcome the axial force. The tilting moment and radial force loading in any kind of working conditions allow the contact angle to be adjusted accordingly.
Four point contact ball slewing bearing in the main consist of a inner ring, outer ring, a single row of steel balls, and a cage (or spacing block). Four point contact ball slewing bearing inner ring, outer ring have integral and split structure. The rigidity of the integral rings is relatively good in holding its rigidity. The split structure is fastened by bolts, this facilitates for a more convenient adjustment process. Normally four point contact ball slewing bearing have cages (or spacing blocks).
Bearing support is widely used in machinery. Construction machinery is used in some common and special times, and their fingers are initially used in some very wide areas, such as some earthwork or some depth machine
