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 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.

This bush is made out of a composite material that has a modulus of elasticity of between 500 and 6000 N/mm2, said bush having at least one lip formed directly at the time of manufacture as an overrun edge of its bore to act as a leak-tight or protective barrier after mounting on the shaft by creating a tightening effect between the inside diameter of said lip or said lips, and the outside diameter of said shaft.
