PU

This collection holds PU with polyurethane and metal treads, made to replace worn wheels on carts, dollies, racks, and equipment. Wheels in this collection range from 600 to 3,500 lb per wheel. Wheels in this category range from 3-1/4 up to 12 inches in diameter with 1-1/2 to 3 in tread widths. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Metal wheels roll with low effort and handle debris and heat. They are loud and can mark finished 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. Measure the old wheel or caster before you buy. Polyurethane aisle: polyurethane casters. Caster hub: heavy duty casters.
