Abstract
A caster includes a support plate and a yoke adapted to support the support plate, the yoke being pivotably joined to the support plate for rotation about a generally vertical axis. An axle is support by the legs of the yoke and at least one wheel is rotatably supported on the axle. A first ball bearing assembly is provided including a bearing race surrounding the axis of rotation of the yoke and a plurality of balls housed in the race. A second ball bearing assembly is spaced from the first ball bearing assembly and is positioned above the axle, the second ball bearing assembly being adapted to transfer a substantial majority of the weight applied on the support plate to the caster wheel.
