SPU

Diameter: 3 to 8 inTread: 1-1/4, 2 inCapacity: up to 1,400 lb
SPU covers bare polyurethane wheels sized for industrial caster forks. Typical builds show wheel diameters 3 to 8 in, polyurethane treads, and capacities 300 to 1,400 lb. Match bore, hub length, and overall wheel width to the fork before ordering a bare wheel. Keep diameter and tread width the same as the worn wheel to preserve overall height. These medium-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
