As detailed by Hamilton Caster in their article “Heavy Duty AGV/Continuous Duty Casters,” Hamilton’s latest series showcases forged steel caster construction and HPI® swivel technology. Originally developed for AGV applications, HPI® surpasses traditional CNC-machined ball raceways, kingpinless, and unit load bearing swivel constructions.
Hamilton engineers have specifically chosen DuraGlide® polyurethane tread for its easy rolling, quiet operation, and excellent performance. To enhance durability and support larger precision ball bearings for extended life, the wheel cores of the 3”, 4”, and 5” wide wheels were upgraded from cast iron to forged steel. Engineers also designed press-fit top hat spanner bushings to eliminate axial play and reduce noise.
The outcome is a robust caster series built to endure continuous heavy-duty use and provide years of reliable performance. This series includes both single wheel (EHD, ES, EHS) and dual wheel (EHD2, EHS2) models, with dual wheel options offering increased stability and higher capacities.
