Engineered for heavy tubular machinery, industrial racks, and rugged service carts, our 101-150 kg (222-330 lbs) threaded stem casters deliver robust screw-in mobility. To withstand intense shear stress and prevent stem bending under demanding weights, they feature heavy-duty reinforced threads. Built strictly in sizes of 2 inches and above with impact-resistant, non-marking treads, they ensure smooth obstacle clearance and reliable locking options. Can’t find what you need?
