Bearing filter

[simplechamp]

I don't agree with the first part nuz69. Bearings get dirt in them, regardless of if they are supposed to be shielded or sealed, especially as the bearing components wear and the gaps between rotating parts (though very tiny) get larger. Best thing to do is perform routine maintenance to clean the dirt out, and use just a tiny amount of thin oil when relubricating. The foam filter he is using definitely won't hurt.

I do agree that too much or too thick oil and grease can just gum up the bearings and keep dirt in.
