470 Series polyurethane and cast iron casters sized for heavy industrial carts that tear up kingpin races. Catalog chips cover top plates around 5-1/4 x 7-1/4, wheel diameters 6, 8, 10, 12 in, and polyurethane and cast iron treads. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. Larger plates spread bolt stress on thick frames under continuous tow abuse. These heavy-duty options cover everyday heavy industrial carts that tear up kingpin races without jumping to extreme forged series.
