ABSTRACT:
An improved wheel and bearing assembly for a load transporting overhead trolley with a load support bracket having opposed stems mounting laterally offset wheels in rolling engagement with an overhead track has wheel-incorporated radially inner and outer race members with anti-friction load bearing balls between them in an annular trackway. The radially inner race member is split offset from the line connecting the center of the balls and formed of mating laterally outer and laterally inner abutting members which have laterally mating non-compressible radially abutting surfaces with radially aligned annular grooves therein. A circumferentially compressible retention spring is carried in one of the annular grooves and resiliently projects radially from the groove so that a snap fit is achieved when the inner race members are moved relatively laterally into mating assembly.
