Match a 4 x 6-1/4 top plate when bolting casters under heavy industrial carts that tear up kingpin races. You will see wheel diameters 6, 8, 10, 12 in, rubber treads, and capacities 750 to 1,200 lb across the SKUs listed below. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete.
