Engineered for heavy-duty tubular racks, industrial carts, and rugged manufacturing equipment, our 201-907 kg (443-2000 lbs) threaded stem casters deliver extreme screw-in support for massive loads. To prevent catastrophic stem snapping or thread stripping under extreme weight, they feature exceptionally thick, heavy-duty reinforced stems. Built strictly in robust sizes of 2 inches and above with impact-resistant, non-marking treads, they ensure smooth mobility over rough facility floors and offer reliable locking options.
