1) 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.
2) Mainly Four Standard Series:
1. Single Row Four Point Contact Ball Slewing Bearing (non gear,external gear,internal gear)
2. Single Row Crossed Roller Slewing Bearing (non gear,external gear,internal gear)
3. Double Row Ball Slewing Bearing (non gear,external gear,internal gear)
4. Three Row Roller Slewing Bearing (non gear,external gear,internal gear)
3)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.
4) Application:
Construction Machinery (Cranes, Excavators, Loader, Scraper)
Heavy Equipments ( Mining equipment, Marine equipment)
packing machinery
metallurgical machinery
Wind power Field
Military products.
5) Material: 50Mn,42CrMo or 42CrMo4v
