When applications call for extra-heavy duty, this series meets the requirements. With load ratings up to 3,500 lbs. per caster and 3-inch tread width wheels. The casters are built from heavy plate steel with heat-treated ball races, hardened bearings and sealed raceways. Equipped with a hardened 1-inch king bolt welded to the top plate that will not stretch or break loose. Heavy-duty features include precision tapered roller bearing with seal that keeps dirt and dust out, while greasing purges old lube. Wheels are available for all types of floor surfaces and job conditions. A pinned, slotted nut is used to adjust the swivel bearings to give you smooth and accurate swiveling.
