5″ Caster Assembly – STR03002

The wheel, bearing, and swivel mount arrive as one 5 inch caster assembly, ready to bolt on in place of a worn unit rather than rebuilt piece by piece. The 5 inch wheel diameter sets the ride height and the load the caster carries under a chassis or cart.

A caster reaches the end of its life when the wheel flat-spots, the tread separates, or the swivel bearing binds and drags, and swapping the whole assembly restores smooth rolling in one step. Match the 5 inch wheel diameter, the top-plate bolt pattern, and the overall mounting height to the caster coming off, since these govern whether the replacement sits level and turns freely.
