Abstract:
1. A guide member comprising a ring for mounting a pin with friction, articulation and/or sliding capacity, the guide member being adapted for mounting in a bore of a support, wherein: the ring and/or the pin is subjected, at least at a friction surface of the ring and/or the pin, to a surface hardening treatment by diffusion or structural transformation, followed by finishing surface treatment of surface oxidation or phosphatation reaction, followed by a treatment for reducing tendency to jamming and for reducing friction coefficient; the friction surface of the ring comprises a bore of the ring and has grooves acting as a grease reserve, the grooves are located at least between channels formed at each end of the bore of the ring and communicate with said channels, depth of the channels being about 1 to 10 times higher than depth of the grooves; and an outer periphery of the ring is joined to an element made from a deformable flexible material engaged in the bore of the support.
