Abstract
A pivot/rotational device comprises a pivot pin having a head and a tubular, cylindrical shank of reduced diameter projecting from the head. A two-part bushing assembly comprises a ring and a sleeve. The ring encircles the shank. The sleeve is formed of anti-friction material and is disposed concentrically between and in surface-to-surface contact with the ring and the shank. The sleeve has a radially outwardly extending collar at one end disposed between and in surface-to-surface contact with the head and one end of the ring. The tubular shank has an open end opposite the head provided with a radially outwardly extending flange which overlies the other end of the ring. The ring is restrained from axial movement between the collar and the flange. The sleeve may also have a second collar between the flange and the ring.
