4" x 2" Green Polyurethane on Cast Iron Core - 800 lbs Cap
CasterHQ's Green Polyurethane elastomer tread is chemically bonded to a black cast ironcore.
Offers higher weight capacities while providing good floorprotection and a smooth quiet rolling operation.
Optional precision ball bearings require less effort to start-up and maintain a rolling load; theyalso generate less friction heat and may prolong the life ofthe wheel.
Works well in both indoor and outdoor environments;however, a cast iron core can rust; if this is an issue look atusing aluminum or plastic core wheels.
