small diameter seal
small diameter seal
(OP)
I have a 5" diameter wheel, hollow inside, which rotates around an 11mm axle. I need to provide a water proof seal to keep water out of the interior of the wheel. I can't use a traditional lip seal since I can't get surface finish good enough and the wheel will not always be "true". O-rings wear too quickly.
Any ideas?

RE: small diameter seal
If the wheel is formed of 2 halves then the bushing could be shouldered to be captured by the halves.
Any other seams that might allow water to enter ??
