Heavy-duty industrial carts use polymer-covered wheels to reduce noise and
limit damage to floors. The Omega Wheel line of heavy-duty casters goes further,
with a patented cast-spoke design that permits it to deform locally when
encountering irregularities or debris on floors then return to its regular shape
once the obstacle has been cleared. In combination with a proprietary blend of
low-thermal-conductivity polyurethane, the open-spoke design runs cooler than
solid wheels, lessening the chance of debonding of wheel and hub.
Polyurethane's resilience results in a quieter wheel less apt to tear or pick up debris. In many cases, this unit allows users to switch from a spring-mounted caster to a simply supported design. Supplied as complete casters with patented kingpin-less construction or as easily retrofitted wheels, Omega Wheels are available in a range of capacities and sizes.
