CORROSION RESISTANCE

We are frequently asked if our combined roller bearings and mating steel profiles are available in stainless steel.

Total demand would mean small batch runs and the cost of stainless steel would make such a product prohibitive in price so we have investigated alternative methods of making our bearings and steel profiles corrosion resistant.

We can offer 2 methods:

METHOD 1

THIN DENSE CHROMIUM PLATING

A thin deposit of Chromium from 1 to 15 microns thick is deposited on all or selected surfaces.

These meet ASTM adhesion and bend tests. Surface hardness shows no brittleness or micro-cracks

when viewed at magnification x 500.

Samples shall pass standard ASTM B-117 & B-287 Salt spray tests. A detailed brochure on this specific method is

available on request. Click here to see more about this process

METHOD 2

EXTREMELY THIN GALVANISED PLATING

Zinc, Iron with yellow chromate passivation to a thickness of 0.5 to 3.0 microns is deposited on selected surfaces by cathodic action.

Test procdure DIN 50 021 (ASTM117) salt spray test utilised.

More details are available on request.

Both techniques are carried out by these specialists NOT BY EURO-BEARINGS.
