Polyurethane On Steel Caster Wheels: Your Caster Connection
Featuring weight capacities of 500 to 4400 pounds per wheel, the 95 Shore A polyurethane elastomer is chemically bonded to a semi steel wheel core and has an operating temperature range of -40 to +180 degrees Fahrenheit. Poly on steel wheels offer high weight capacities while providing good floor protection, and works well in both indoor and outdoor environments. The wheel core can rust when wet, so this wheel is not recommended for applications which operate where water is present.
