Nylon bearing?
I'm in the process of fabricating a throttle linkage, which will have a roatating metal arm. I plan on 'mounting' this arm to a
bolt.
However, how do I stop the arm sticking on the bolt, suspect I need some type of bearing.
Is nylon/plastic suitable and if so where can I get something suitable, or are there any other suggestions?
Thanks as always.

I have used nylon rod ends from RS componants, on my gearchange. The steel ones I used a first tended to bind up if the smallest amount of dirt got
in. The nylon ones will allow for a rod to slide through them without binding. I sprayed them with some white grease which helps.
I haven't had a problem since.

Confused but excited.

The choice of bush material is determined by which is easier/cheaper to replace. A brass bush will wear before the steel bolt. A nylon bush will
absorb grit and dust, but the bolt will wear.
Tell them about the bent treacle edges!

I used a pair of oilite bushes for my home brew throttle linkage. No problems after over 5k miles.

You can get proper bearing nylon - I think it's loaded with graphite or something. Just as machinable, but makes a respectable low-stress
bearing (like a shaft support).

I think it was called Nylatron, loaded with molybdenum disulphide.
By using loctited oilite bushes I was able to ensure that the bearings were aligned so that there was no binding that can occur with low precision
assemblies.
