8" x 4" Rigid Plate Caster with Ductile Steel Wheel
Ductile steel is a composed of a combination of special alloys that give it higher weight capacities than cast iron; while being more economical than drop forged steel. Also referred to as malleable iron; material may flex rather than cracking or breaking when submitted to an extreme shock load. Features an extra thick walled, heavy-duty core, hub and tread face. Roller bearings are standard, with precision & tapered bearings as an option.
Idea for use on rough surfaces and has good rolling resistance under any condition.
