What is Purpose of O-Ring that Comes with Spindle Grease Seal Set BB60002

Published 07/26/2018

Question:

I must be missing something, what does the o-ring do if it is on the outside of the sleeve? Its purpose is to create a seal between the new sleeve and the spindle, shouldnt it go between the two parts? Why not put it under the sleeve so it is compressed between the shoulders of the spindle and sleeve?

If you check out the diagram I attached you'll see how the O-ring of the Bearing Buddy Grease Seal set part # BB60002 installs. It's location is designed to compress between the seal ring and grease seal to help prevent the seal from leaking or failing. With Bearing Buddies people tend to put too much grease in the hubs with them so this acts as a way to help brace the seal and prevent failure.
