Super High Capacity Polymer Wheels - 4" thru 12" Wheels - up to 8,000 Lbs

These polymer wheels are a high capacity choice for heavy carts on smooth concrete. Wheels in this collection range from 2,200 to 8,000 lb per wheel. Diameters in this category range from 4 to 12 in in 2 and 3 in widths. Polymer rolls easily under load and resists many chemicals and oils. It is harder than rubber, so it is louder on rough floors. Match the bore, hub length, diameter, and tread width before you order. Capacities below are per wheel unless a listing says set. Confirm the load rating printed on the title before you order. Read the listing for the exact wheel size, overall height, and mount shown. Measure the old wheel or caster before you buy. Verify the stem or plate matches your old unit before you buy.
