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 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 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° F or for more than 30 minutes
continuous operation you 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" ) should be used on smooth
floor surfaces. 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 any high
temperature application always best to 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.
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.
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.
