Chrome Plated Ball Races
Chrome Plated Ball Races
(OP)
We are going to use some ball bearing linear shaft bushings in an application. Because of a long term corrosion potential the salesman has suggested shafting with hard chrome plating. I always thought that chrome steel balls running on chrome plating was not a good idea; flaking of the chrome due to ball contact pressure. I'm I just dreamimg this?

but not on ball races. I think your concern
is on the money.

There are corrosion resistant products from the major manufacturers (THK, Rexroth/ Deutsche Star/ Thomson) as well as fully stainless steel products - let alone the new plastic slide systems (Pacific / IGUS) to name a few.
Hope this isn't too late to help.

I had the same response you did I when I first heard this proposal. Years ago I saw the problem you describe when chrome plated shafting was tried.
It now appears that the combination of case hardened shafting and thin dense chrome has solved the problem.
RE: Chrome Plated Ball Races
This equipment was probably some of the first to use this particular shafting.
Chrome plating for industrial purposes has been and probably still is misused for a lack of understand of the nature of same.
Aside from the misuse of different types of plating there seems to be a lack of knowledge in the application of industrial hard chrome. Being, IHC takes on the properties of the base metal until the thickness exceeds 0.011". We like 0.015" if possible.
