A caster wheel comprising a wheel mount and a bearing plate, both having a pivot pin extending through them such that the wheel mount may pivot relative to the bearing plate. The wheel mount and bearing plate both have at least two magnets each, arranged such that pivoting movement of the wheel mount may position the magnets in registry with one another. The magnetic attraction between the magnets further attracts the wheel mount and bearing plate into registry with one another, aligning an article to which the caster wheel mounts in a straight direction.
