Abstract: A hinge assembly for garage doors having two leaf assemblies and a central tubular supporting member. A sleeve member is coaxially mounted within the supporting member and in turn it coaxially houses a roller shaft extending beyond the supporting member. The shaft has a roller mounted at one end. A push nut fastener mounted to the shaft member and the sleeve member abuttingly mounted to one end of the inner sleeve member. The leaf assemblies' movement is constrained along the tubular supporting member. The sleeve is made of a self-lubricating plastic material.
