Abstract
A greased joint assembly operating in oily conditions comprises an axle mounted rotating or pivoting in a ring. The axle and/or the ring are subjected to a hardening surface treatment by diffusion or by structural transformation followed by a finishing surface treatment and a treatment suitable for reducing the tendency to jamming and for reducing the sensitivity to corrosion, and the bore of the ring and/or the axle is provided with arrangements acting as a lubricant reserve.
