DUA/TUA - SIRIUS Heavy Duty Polyurethane on Al

This collection holds Dua Tua Sirius Heavy Duty Polyurethane On Aluminum Wheels with polyurethane and polyolefin treads, made to replace worn wheels on carts, dollies, racks, and equipment. Wheels in this collection range from 550 to 2,000 lb per wheel. Wheels in this category range from 3 up to 8 inches in diameter with 1 to 2 in tread widths. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Polyolefin is light, low cost, and resists water and many chemicals. It is hard, so it is loud on rough floors. Match the bore, hub length, diameter, and tread width before you order. Order the axle and spacers if the old ones are worn. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Polyurethane aisle: polyurethane casters.
