These 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 Service, Schools, Bakeries and other Institutional applications.
The Extra Thick, softer
Durometer, CP Polyurethane on Aluminum wheels provide more cushion than thinner
polyurethane wheels. Extra Thick CP tires help to protect cargo, minimize
vibration and are more resistant to bond failure caused by metal shavings. They
roll more easily over small obstructions such as uneven expansion joints. These
high capacity wheels have extra large precision sealed ball bearings.
