ABSTRACT:
A pivot assembly has a substantial amount of inherent frictional torque. A shaft has a clearance space between itself and a wall of its journal hole. A pliable tubular bushing is axially compressed within the shaft clearance space to create rotational friction between the shaft and the bearing journal. Such an assembly has diverse applications in areas such as the swivel for sailboat tiller extensions, toilet seat lid hinges, and hinged covers for electronic cabinets or other equipment.
