View Full Version : How to keeps axles from rusting

Does anyone have a good idea for how to keep axles/jackshafts from rusting that won't add so much thickness that they no longer fit through bearings and hub adapters?

Your best bet is Zn coating (galvanizing).
A layer starting from 15 micron can be deposited.

That means 30 micron increase in diameter.
0.03mm or 0.0011811024 in
Less than usual cold rolled/bearing tolerance.

Cost is similar to a spray can.

But you do must have clean welds (if any) and cleaned parts.

Only issue is to find a local shop to do it ...
Luckily, i have plenty of choices but you might not.

Paint them in situ?

Paint them in situ?

you cannot dismantle unless you strip off the paint , burn oil into them is another way , if you have no other option or engineers blue

As Emma said.

Any non microscopic covering after installation will make it a PITA on maintenance/removal time.
And i don't know any painty stuff under 100 micron/layer so ... (except powdercoating which comes at least 70 microns) ...

And don't even start me on putting oily/greasy stuff on anything exposed to the elements.
In my experience it does not stop rust (for long - days - maybe weeks if you're lucky), it will just slowly "disappear" but it will make dust/dirt heaven and that won't slowly disappear ...
And oil/dirt combination does not protect against water damage (if it only could), it just makes things messy.

There is another way, a way discovered to me on these same forums not so long ago, one i'm cringing about but others are ok with it.
It's called "natural finish".
Yeah, i mean, who cares about rust anyway ?
And what's the point of removing it ?

Pick your poison ...

Thanks for the ideas. I'm looking for a galvanizer, but maybe I just have to change the jack shaft once a year.

Hi Demon327

Here's another thought.
