Any clues on where to get plastic bushes?

[Badshot]

Need some bushes, can't source from manufacturer, dealer tried for 4 years, useless.
70mm od, 2-3mm thick, 70mm long, obviously they can be longer and cut down.
I just don't seem to be able to find anything.
If it was thicker I'd get some turned out of nylon, but I think they're too thin to hold shape in a lathe.

I thinks some of the jcb diggers use plastic bushes on some of the pins. May be worth talking to your local dealer?

Check the bearing suppliers online like bearing boys etc they sometimes have nylon/plastic bushes.

Maybe you cannot hold them in the lathe with regular gear but you might with specialist tools. Maybe ask an engineer?

They do, but I haven't managed to find anything yet.

Speak to any engineering company , they will be able to turn them out for next to nothing.

Something this thin tends to be a rolled sheet of metal/polymer mainly for grease retention.

It's sliding bushes on a flail topper offset.
Yet another reason not to buy machinery that isn't well known/established.
It's a good topper but has zero backup.

Apologies all.

Just found my digital measure.
It's 70mm internal diameter.
75mm outer diameter.
70mm length.
Really not worried what plastic it is, so long as it's not brittle.

You could speak to nylacast at Leicester.
They might have something.

Years ago we built a bale trailer and used a 70mm rod from a dipper hydraulic ram as tandem pins. Wanted a bush for it so machined the outside sleeve to suit and used PTO guards offcuts as the actual bush. ( had loads of offcuts from trimming new shafts down to suit different tractor). Whatever plastic they were they’re still there!!!

Lathe Chuck can hold onto the solid bar stock surely while the bore gets taken out. then part it off..
