Hi,

I am having to replace some worn acetal rudder bearings - 60 OD x 40 ID approx.

Outside dimension not a problem since I can measure the ones I have removed but not
sure about the internal clearance needed between the stainless steel shaft and the bearing.

I don't want them binding due to expansion of the stainless steel or the acetal or if this is even a problem.

Anyone with any experiance of this??
