FIELD: technological processes.
SUBSTANCE: guiding device in the form of a metal ring (1) for mounting a pin with friction and with the possibility of articulation and/or sliding, with a ring opening comprising a friction surface and working structures (1a) suitable for storing the lubricant in the friction zone. A self-lubricating coating (3) with low wettability, coated with a lubricant, is applied to the friction surface and the working structures, so that after wear of the self-lubricating coating (3) on the friction surface of the opening, the difference in wettability between said friction surface and the working structures still containing this coating extracts said lubricant from said working structures to lubricate said friction surface.
EFFECT: continuous lubrication in the working structures inside the ring or another component in order to feed a lubricant to surfaces in contact during operation.
