Slewing rings are usually used for low revolution while shaking and strained with an enormous axial force, moment and in some parts with radial force simultaneously
Four main standard series:
Single row four point contact ball slewing bearing (non gear, external gear and internal gear)
Single row crossed roller slewing bearing (non gear, external gear and internal gear)
Three row roller slewing bearing (non gear, external gear and internal gear)
Consequently the requirements for loading are stricter than ordinary bearings
If the selection of the bearing has been wrong it will cause a great damage
Hence it is necessary to evaluate the exact forces acting on the slewing ring and to select the suitable slewing ring
Application:
Construction machinery (cranes, excavators, loader and scraper)
Heavy equipments (mining equipment and marine equipment)
packaging machinery
Metallurgical machinery
Wind power field
Military products
Materials: 50Mn, 42CrMo or 42CrMo4v
Special treatment (blacked and phosphating)
We can provide special service according to customer’s requirement
This method slewing bearing is after special treatment and has the function of anti corrosion
it is widely used in many fields that need to be anti corrosive, such as container crane, steel mill which adapt to the damp and bad circumstance, so the life of the slewing rings will can be relatively extended
