Semi-steel cast iron provides a long lasting, high capacity wheel capable of easy rolling under heavy loads. These cast iron based wheels feature a machined hub and wheel face.

Featuring a Kingpinless hot forged ASTM1045 steel design that increases caster durability and integrity, the series KP30 eliminates problems associated with kingpin failure due to severe shock loading. In addition, the Kingpinless design features 3/8” diameter HRC45 steel ball bearings which absorb thrust and load in severe environments.
