Bearing Issue - Any Opinions

[Deleted Member 4613]

The company that was going to supply the correct size sealed
bearings for me to convert the 4 stroke belt drive to bearings
has stated that they can only supply an open face bearing in
the size I need: 20x15x4. I'm concerned that grease from the
bearings will migrate to the clutch, so I'm not sure I should
order them. Any opinions?

Can the area that houses the bearing be made larger to house a slightly larger outside diameter?

Yes, I already reamed out the clutch cover to accept a 20mm OD
Olite bushing, and I would have to ream it to 21mm to accept
a 15x21x4mm sealed bearing which is available in stock. I was
hoping to find a sealed 15x20x4 bearing but they are not
available..

Some times we do what we have to do. Are you going to need to build the outside of the bearing housing walls up, since you're taking another mm out of the inside? Hoping for your sake the bearing housing walls don't get thinned out to much.

I'm just thinking if you have to weld around the outside wall of the housing to thinken the wall; you might want to do the build up first. Then remove the mm from the inside of the bearing housing.

Maybe use a dry lube

A dry lube? A lube that doesn't migrate and won't thin out
under heat. I'll explore this.

Was switching out to a sealed bearing being done so that you didn't have to keep lubricating the bearing like you do with the oil-lite bearing?

No, I never exhausted the olite bushing. But I dream of a
permanent bearing solution.

I'm not saying the oil-lite has to be relubed a lot but eventually will need it unlike a sealed bearing.

Right.
