Series 52K Standard Duty Kingpinless Casters

Hamilton's Standard Duty Kingpinless Caster series is an excellent choice when requirements call for tough kingpinless polyurethane wheels, and budgets are tight. These casters are a significant upgrade from traditional cold-forged wheels, thanks to their enhanced durability. These casters are also easier to swivel under load. From a durability and price point scale, this series is positioned between Hamilton's cold forged 52 series and the forged steel Spinfinity Workhorse Series. To learn more about these high-quality wheels or to discuss the sizes available, including 5-inch caster wheels, reach out to our office.

Our Typical Kingpinless Wheels

Typically, the standard duty kingpinless casters start with inner and outer raceways made from 1045 steel. The raceways are then CNC machined for precision swiveling and heat-treated to hard 45-50 Rockwell C for long wear. Quarter by half-inch formed legs are then welded on both sides of the raceways for extra strength. Also, a sealing cap is welded to the outer raceway to keep foreign material and grease from entering the caster. The wheels are then finished with a bright zinc plating.
