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.

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

The ring or the component have workings to supply grease to the friction area at given time intervals, with the bore of the ring having workings able to act as a grease reserve. The ring's bore has facilities suitable for putting the grease supply workings in communication with all the workings suitable to act as a grease reserve.
