High Temperature Caster Wheels

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, dry heat bakery ovens and dry heat autoclaves. Temperature Rating: Up to 475° F for 30 minutes MAXIMUM continuous operation. Then allow to cool to room temperature. If used above 475° F for more than 30 minutes continuous operation it 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 perform best in moist heat applications such as in smokehouses, moist heat bakery and autoclave applications and around water and steam. Temperature Rating: Up to 425° F for 30 minutes MAXIMUM continuous operation. Then allow to cool to room temperature. If used above 425° For for more than 30 minutes continuous operation it will reduce the life of the wheel. High Temperature Glass-Filled Nylon wheels are not recommended for dry heat applications because once the moisture content of the wheel gets to zero, the wheel will shatter.

Both the High Temperature Phenolic Wheels ( prefix "TP" ) and the High Temperature Glass-Filled Nylon wheels ( prefix "NP" ) have a hard surface and should be used on smooth floor surfaces. If the floors are rough or if there are obstructions which will impact these wheels it will reduce the service life of the wheels. In any high temperature application it is always best to shield High Temperature Wheels from a direct heat intake source.

The above 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 1/2" axle. Some sizes are available with a 3/4" Plain Bore upon request.

Sterilizer wheels have a prefix "HTR" and are made with an engineered rubber tire bonded to a stainless center. They provide quiet rolling, a cushion ride, and floor protection. These wheels were designed for use on equipment in hospital and laboratory sterilizers and autoclaves. They are also used in other high temperature applications where a cushion ride is needed to protect product being moved. Examples include commercial bakeries and aerospace plants. These wheels are never to be used above 300 degrees Fahrenheit. They should not be used for more than 1 hour continuous or 2 hours intermittent operation. Our load capacity rating for the 4 x 1.50 wheel is 200 Lbs, and for the 5 x 2 wheel is 300 Lbs. under ideal operating conditions. The 4 x 1.50 wheel has stainless ball bearings and comes with a bushing to fit a 3/8" axle. The 5 x 2 wheel has a bronze bearing and fits on a 1/2" axle.

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.

Maximum Capacity under ideal conditions.
If your application exceeds 40 minutes at the maximum temperature rating for these wheels contact us at 800-501-3808 for a recommendation.

You should never select on the basis of load capacity alone. Capacity ratings do not take into account the effort required to manually move a load. Capacity ratings are based on manual operation under ideal conditions. If these wheels are going to be moved by mechanically powered equipment, consult us for a reduced capacity rating based on your application.
