Urethane on Iron Wheels

Urethane on Iron wheels feature liquid-cast polyurethane tires molded onto heavy duty iron wheel cores.  These wheels are impervious to oil, grease, many solvents, and are non-conductive and non-sparking.  Urethane on Iron wheels are a common choice for casters in power towing applications. 
Standard urethane tires have a hardness rating of 90-95 durometer (Shore A). 
Northwest Caster stocks a full range of standard Urethane on Iron wheels in diameters up to 10".
Larger wheel diameters and custom urethane-tired wheels, including drive wheels, are available by special order.
