The reason for the seals is an easy, but Misunderstood reason. The seals are there to prevent small chunks of normal gear/synco wear from entering the bearing and shortening it's life.


Do you think that's why the one bearing failed and the others didn't? (It seems logical to me. I think I take back my earlier statement about there being no cause and effect). Any idea why the bearing that failed didn't have the seals?

I understand what you're saying about getting the bearing out <img src="/forums/images/graemlins/kewl.gif" alt="" />
