Abstract

The bore of the ring has workings () suitable to act as a grease reserve at the friction area. A self-lubricating coating () with low wettability is applied to the entire surface of the said bore, including in the workings () suitable to act as a grease reserve, such that after wearing of the layer of self-lubricating coating at the friction surface of the bore, the difference in wettability between the said friction surface and the workings still having the coating, enables the grease to be drawn out of the said workings in order to lubricate the said friction surface.
