Hamilton SEC Super Endurance Kingpinless

Capacity range 680 to 6,000 pounds

The SEC Super Endurance Series casters represent the "best of breed" in kingpinless style design for extra heavy-duty applications. These heavy-duty casters have a top plate, and the inner raceways are designed as one piece, which provides a superior raceway for shock conditions. We use CNC machining to harden to ensure the raceways are uniform with the same depth. This process produces a highly reliable and convenient swiveling caster for extreme loads.  All Hamilton Casters under the Super Endurance Series are finished in gray enamel and come standard with 12 different wheel types.
