A controlled caster wheel assembly which can be universally adapted to various support and directional control applications. The control mechanism is the caster beam assembly which attaches to a caster wheel assembly. The caster beam assemblies have both a cam/cam follower mechanism and a weight sensitive clutching mechanism which stabilize the caster wheel assembly thus preventing indiscriminate motion of wheel due to tire to contact surface variations. The controlled caster wheel assembly can be universally applied to any design which uses single or multiple wheels as support and directional control.
