Thermo wheels feature a standard operating temperature range from -70°F (continuous service) to +525°F (intermittent service, 475°F continuous service). These are molded from an exclusive engineered resin compound that offers non-marking floor protection, near zero water absorption, high load capacities and long service life. A special manufacturing process enables these wheels to retain a consistent bearing bore even when exposed to elevated temperatures. Furthermore, Thermo wheels are 100% recyclable, and they are highly resistant to animal fats, vegetable oils and salt solutions. The life expectancy of Thermo wheels is three times longer than high-temp phenolic wheels, and they offer an equal load capacity. Unlike high-temp phenolic wheels, Colson Thermo wheels have no outer skin that can break and absorb water or other fluids.
Temperature range: -70°F to +525°F intermittent service, (+480° continuous service).
Hardness: 85(±5) Durometer Shore D scale.
