Abstract
A guide device includes: a metal component in the form of a bush provided with a friction surface intended to receive a mating part in frictional contact by sliding with oscillation; a wear sensing system of the friction surface having one or more sensors; and a wireless communication system connected to the detection system and configured to transmit information relating to the wear of the friction surface out of the guide device. The sensor or sensors are arranged exclusively on one longitudinal side or on two longitudinal sides of the bush, each longitudinal side being defined over at most two fifths of the length of the annular bush.
