Acetal on acetal bearing. Will it work?
Acetal on acetal bearing. Will it work?
(OP)
I have been offered a quantity of surplus acetal top hat style bushes that I am considering using for suspension pivots. The drawback is, the ID is quite large and I do not want to use a large internal steel bush because they will weigh too much.
For lightness, can I use acetal for the internal bush too(supported by a class 10.9 bolt) and operate the top hat bush on that?
Would the acetal on acetal cause to much stiction? If it is OK can anyone suggest running tolerances?

RE: Acetal on acetal bearing. Will it work?
I have no idea of actual tollerances, other than to say that acetal shackle bushes I have used on the rear suspension of a 3/4 tonne V8 powered, passenger car based van, had a non rattle but slightly loose slip fit, I guess about 0.002"clearance on a 7/16"or 1/2" pin. It was a long time ago, so I don't remember exact dimensions.
