Surface phosphating treatment small diameter selwing ring bearing 010.12.318 without gear on sale
Phosphating is a chemical process used to deposit metal-phosphate layers that are hardly soluble on steelsubstrates. The layers created are porous, absorbent and suitable for powder coating. They are also suitable as temporary corrosion protection if subsequently treated with oil, water or passivations.

We also have other types slewing bearing as below:
A slewing bearing or slew[ing] ring is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. (To "slew" means to turn without change of place.)
Compared to other rolling-element bearings, slewing bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metres diameter and fit over a 3.5 metre axle. Slewing bearings resemble oversize aircraft control surface bearings.
Characteriestic of structure, performance and application
The single row four point contact ball slewing bearing is composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four point, it can bear the axial force, radial force and the tlting moment at the same time.
It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator, and other construction machinery.
Note:
1. n1 is the nos of lubricating holes.Oil cup M10×1JB/T7940.1~JB/T7940.2.The Oil nipple's location can be change according to the user's application.
2. n-φcan change to tapped hole,the diameter of tapped hole is M,depth is 2M.
3. The tangential tooth force in the form is the max tooth force,the nominal tangential tooth force is 1/2 of the max one.
4. "K" is addendum reduction coefficient.
