Polyurethane on Cast Iron Wheel Casters

Molded on polyurethane wheels use a non-marking green polyurethane tread that is chemically bonded to a cast iron core. Polyurethane wheels resist tread flat spots from long periods of standing. Equal in strength to a cast iron wheel, but also floor protective, resistant to oil, grease, water, and many solvents, and easier rolling. Wheel tread hardness of 90-95 Shore (A) Durometer.
