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:*0Mn,*2CrMo or
*2CrMo4v
6) Special treatment (Blacked,
phosphating)
We can provide sepcial service according to
customers requirment.
This method *****- slewing bearing is after
special treatment, and has the function of anticorrosion……….it
is widely used in many fields that need to be anticorrosive,
such as container crane, steel mill…….which adapt to the damp
& bad circumtance, so the life of the slewing rings will
can be relatively extended.
Once you inquiry, I will get back to you very
soon.
