ABSTRACT:
An improved caster wheel assembly for a wheelchair or the like includes adjustable bearing components for variably resisting swivel motion of a caster wheel to prevent undesired wheel flutter. The caster wheel assembly includes a wheel fork unit having a rotatable caster wheel, and a housing sleeve adapted for mounting onto the frame of a wheelchair or other castered device. An upstanding swivel post on the wheel fork unit is supported within the housing sleeve by the bearing components for rotation about an upright swivel axis. The bearing components include an outer bushing mounted on the housing sleeve, and having a conical bearing surface for axially engaging a mating bearing surface of a longitudinally split inner bushing. A nut threaded onto the swivel post urges the inner bushing axially against the outer bushing with a selected adjustable axial load to resist rotation of the swivel post, and thereby resist undesired rotational flutter of the swivel post and the associated caster wheel.
