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)
Â
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.

6)
Special treatment (Blacked, phosphating)
Â
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.
