Metal combinations for a plain bearing

[David Murray 1Participant @davidmurray1]

How about IGUS bearings – **LINK**

Fantastic things, we used to use them under railway carriages for brakegear with no lubrication. Have a range for all sorts of environments. I notice RS sell them – **LINK**

Their M250 Range goes down to 1mm shaft size – https://www.igus.co.uk/product/5 and is good for general dirty environments.

I think his is the best solution particularly if used on a hardened stainless steel pin.

In view of the abrasive environment, would it be possible to fit small 2RS ball races, to have low friction and reasonable protection from the abrasive slurry? MIght even be worth modifying the holder for this?

This question has attracted a lot of creative responses – thanks to all for suggestions, I can't try everything, so I just have to go with gut feeling – the MKIII is going to be cone and cup as in the toy gyroscopes. I think this gives me the best chance for the user to adjust for wear.

I'll post a pic of article when done – thanks again for all the ideas, much appreciated.

Robin.
