ABSTRACT:
Fluttering of caster wheels having a swivel mechanism including ball-type or roller-type bearings is effectively prevented by substituting, for some of the steel rolling elements of the bearings, resilient rubber-like rolling elements of somewhat greater diameter. Flutter resistance and steering characteristics of the caster can be varied by varying the size of the resilient rolling elements, or the proportion of resilient rolling elements to steel rolling elements in the bearing.
