Hamilton caster wheels are ideal for use with medical equipment, furniture and store fixtures. The brand's economic Kingpinless casters feature an unconventional upper raceway, that is CNC-machined and then hardened to ensure a uniform depth and provide vertical load handling capacity. These casters are available in double-sealed precision ball, tapered precision and straight roller bearing variants. The Hamilton Precision Integrated (HPI) swivel technology of these caster wheels outperforms standard raceways in terms of the bearing's element of contact (almost double), hardness (45 percent more) and smoother surface finish (up to 16 micro inches) . Choose from a wide range of these caster wheels available in cast iron, ductile iron, nylon, phenolic and polyurethane wheel materials on Raptor Supplies.
