Our Energy Saver Polyon wheel is a crowned polyurethane tread bonded to a heavy-duty solid cast iron core. Offering high capacities and floor protection. These wheels are more ergonomic when compared to traditional Poly-On-Iron wheels.

The casters in our 55/56 Series are heavy duty and forged, with capacities up to 3,500 lb. The series offers matching swivel and rigid casters constructed with 3/8″ thick swivel head from hot forged ASTM1045 steel. The legs are 3/8″ thick and the axle used is 3/4″ thick making these casters hold up to the toughest of jobs. The swivel casters feature a integrally forged 1″ diameter kingpin, main load ball bearings that are 1/2″ in diameter, as well as tapered thrust bearings.
