Dual wheel tilted axle caster with an integral retainer and bearing assembly

A dual wheel tilted axle caster assembly including a body having an upper end and a lower end, said body defining a pair of angularly inclined side walls which converge toward each other at said lower end of said body;

• a first cylindrical sleeve coaxial with and extending outwardly from each side wall generally perpendicular thereto;
• a second cylindrical sleeve coaxial with and extending outwardly from each side wall, said second cylindrical sleeve spaced radially outwardly from said first cylindrical sleeve and defining an annular chamber therebetween;
• a pair of wheels each adapted to engage and roll over a surface, each wheel mounted on said body so as to be relatively rotatable with respect to said body and said other wheel, each wheel including an inwardly extending rim, the outer surface of which provides a ground engaging surface, said rim overlying said second cylindrical sleeve;
• a first bearing assembly disposed between said rim and said second cylindrical sleeve for rotatably supporting said wheels on said body;
• means to secure said wheels to said body but to permit relative rotation therebetween.
