High-Temp Steel & Ductile Iron Wheels

This collection holds High-Temp Steel & Ductile Iron Wheels with metal and forged steel treads, made to replace worn wheels on carts, dollies, racks, and equipment. Wheels in this collection range from 600 to 2,500 lb per wheel. Wheels in this category range from 4 up to 8 inches in diameter with 1-1/2 to 3 in tread widths. Metal wheels roll with low effort and handle debris and heat. They are loud and can mark finished floors. Forged steel wheels carry very heavy loads and handle impact, debris, and heat. They are loud and will 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. Forged steel aisle: forged steel casters. Caster hub: heavy duty casters.
