4″ High Temp Glass Filled Nylon Rigid Caster (2.04208.52.HT)

These wheels feature a standard operating temperature range from -70°F (continuous service) to 525°F (intermittent service, 480°F continuous service). These wheels 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 the wheels to retain a consistent bearing bore even when exposed to elevated temperatures. Furthermore, they are 100% recyclable, and they are highly resistant to animal fats, vegetable oils and salt solutions. The life expectancy of the 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: -70ºF to 525ºF intermittent service ( 480ºF continuous service) Hardness: 85(±5) Durometer Shore D scale
