5" Caster Wheel, 935 lb. Load Rating, Wheel Width 1-1/2", Polyurethane, Fits Axle Dia. 1/2

Polyurethane tread on iron core wheels are used on industrial equipment. Wheels with iron cores provide good wear resistance and typically have higher load capacities than wheels with aluminum or plastic cores. Iron will rust if it gets wet, so these wheels are best suited for dry environments.

These wheels have polyurethane treads that provide more resistance to abrasion and chemicals than rubber treads. They also provide quiet rolling and will not mark floors, making them well suited for use in locations where noise must be minimized and an attractive floor appearance must be maintained. Polyurethane tread standard wheels are available in a range of hardnesses. In general, soft treads offer more cushioning and better floor protection than hard treads, and hard treads provide more weight capacity, better abrasion resistance, and easier rolling than soft treads.
