Theres really no point it maintaining your bearings. It is best to just get a bunch of cheap rubber sealed bearings and replace them pretty regularly. If you take the shield off, only to put back on after re-lubing them, you will destroy the tight seal and allow dirt or sand to get into the bearing causing them to fail or break into a million pieces.

Rubber shielded bearings are supposed to have a longer life span than metal shielded ones. In theory by the time the need servicing with cleaning/relube they are near the end of their useful life anyway. I'll still clean-out and relube a gritty rubber shielded bearing. Certainly sometimes this means you'll go to the effort only to find out the bearing is shot, other times the bearing can be re-used. You still want to have fresh spares around in-case it turns out the bearing is done or if you mangle the shield too much trying to get it out! Rubber shielded Bearings can be purchased on-line like from Avid RC so it is definitely worth ordering up a bunch before you actually need one. Bearings from the LHS are usually way overpriced, like a pair for $10! Online youre looking at like $1 each!

Sometimes I can't remove a metal sheild at all. Sometimes I spend a lot of time trying to get under the retaining ring/spring. I think the rubber seals are easier to get out. Of course sometime I mangle a rubber shield.

Oh...and "re-use" is the sincerest for of recycling. Now go hug a tree. Ha ha!

thanks, I'm just the sort of person who is anal about reducing friction and lubing the bearings when I got nothing to do haha.

I'll go and order some rubber shielded bearings from fleebay. They are only about $6 for a whole set.

There are bearings with a metal shield on one side and a rubber one on the other. Allows you to easily relube and also if necessary remove the rubber shield, cleand and relube.
