Durastar DuraTough polyurethane on polyolefin wheels

This collection holds PTU/DTU with polyolefin and polyurethane treads, made to replace worn wheels on carts, dollies, racks, and equipment. Wheels in this collection range from 275 to 1,800 lb per wheel. Wheels in this category range from 3 up to 12 inches in diameter with 1-1/4 to 3 in tread widths. Polyolefin is light, low cost, and resists water and many chemicals. It is hard, so it is loud on rough floors. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. 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. Measure the old wheel or caster before you buy. Polyolefin aisle: polyolefin casters. Caster hub: heavy duty casters.
