Caster City, Inc. 5" x 2" High Temp Glass - Nylon Wheel NP5x2R

5" Diameter 750 lbs. Capacity Wheel. Roller Bearing High Temperature Phenolic Wheels have a prefix "TP" in the part number and are made out of FIBERGLASS. They are best suited for dry heat applications such as powder coating, bakery convection ovens and dry heat autoclaves. Temperature Rating: Up to 450° F for 30 minutes MAXIMUM continuous operation. Then allow to cool to room temperature. If used above 450° F or for more than 30 minutes continuous operation you will reduce the life of the wheel. High Temperature Wheels with a prefix "NP" in the part number are made from Glass-Filled Nylon. They tend to perform best in moist heat applications such as in smokehouses and around water and steam. They are often used in Bakeries and autoclaves as well. Temperature Rating: Up to 425° F for 30 minutes MAXIMUM continuous operation. Then allow to cool to room temperature. If used above 425° F or for more than 30 minutes continuous operation you will reduce the life of the wheel. Both the High Temperature Phenolic Wheels ( prefix "TP" ) and the Glass-Filled Nylon wheels ( prefix "NP" ) should be used only on a smooth floor surface. If the floors are rough or if there are obstructions which will impact these wheels you will reduce the service life of the wheels. In a powder coating application always shield High Temperature Wheels from a direct heat intake source. If your application requires that High Temperature wheels be used at a maximum temperature rating for more than 30 minutes please contact us about a recommendation for a Steel Wheel. Wheels with 1 1/4" tread width have plain bores and a bushing(s) to fit onto a 3/8" axle. Wheels with a 2" tread width have a 3/4" ID Roller Bearing and come with a steel spanner bushing to fit onto a 1/
