Caster HQ's caster wheels are liquid cast polyurethane on aluminum centers. They are used in almost every type of application but are especially popular in Research Laboratories, Hospitals, Food Services, Schools, Bakeries, and other Institutional applications.
They have non-marking polyurethane tires which are easier rolling than Gray Rubber wheels on smooth floors. They withstand exposure to many chemicals and solvents and can be used in industrial applications which do not involve shock, overloading, abuse, obstructions, poor floors, or storage ( standing ) loads.
