High Temperature Wheels with a prefix “NP” in the part number are made of nylon mixed with glass fiber. They perform best in moist heat applications such as in smokehouses, moist heat bakery and autoclave applications and around water and steam such a pressurized steam-autoclave. Temperature Rating: Up to 425° F for  continuous operation. Then allow to cool to room temperature. If used above 425° for more than 30 minutes continuous operation it will reduce the life of the wheel.  Maximum Temperature range is 475° F – 550° F intermittently. 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.

The High Temperature Phenolic Wheels ( prefix “TP” ), the High Temperature Glass-Filled Nylon wheels ( prefix “NP” ), Wheels 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.

High Temperature Phenolic Wheels have a prefix “TP” in the part number and are made with glass fiber. 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 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.  Maximum temperature is 525° F.

Our HTR high-temperature sterilizer caster wheels, offered in 3″, 4″, and 5″ diameters with a 1.25″ width, boast an engineered rubber tire fused to a stainless core, crafted to deliver whisper-quiet rolling in animal testing labs to avoid startling animals and safeguard delicate cargo. Built to endure autoclave cycles at 15 PSI steam pressure and 250°F for 15–20 minutes or 29 PSI at 273°F for 6 minutes, these wheels handle up to 300°F for 1 hour in sterilizers, steam retorts, or high-heat environments like bakeries and aerospace facilities. The soft, non-marking rubber tread ensures a gentle, vibration-dampening ride on smooth floors, with the 4″ wheel (200 lbs capacity, stainless ball bearings, 3/8″ axle bushing) and 5″ wheel (300 lbs capacity, bronze bearing, 1/2″ axle) protecting surfaces while resisting water, oils, and cleaning agents. Paired with corrosion-resistant stainless steel swivel casters, these wheels provide hygienic, reliable mobility for lab sterilizers and high-temperature applications demanding quiet performance.

Our high-temperature soft rubber autoclave caster wheels, available in 3″, 4″, and 5″ diameters with a 1.25″ width, are crafted for silent, smooth operation in animal testing laboratories, preventing disturbance to sensitive animals. Mounted on corrosion-resistant stainless steel swivel casters, these wheels support up to 300 lbs and endure rigorous autoclave conditions, including 15 PSI steam pressure at 250°F for 15–20 minutes or 29 PSI at 273°F for 6 minutes, as well as steam retorts up to 300°F. The non-marking soft rubber tread glides quietly on smooth surfaces, absorbing vibrations to maintain a peaceful lab environment, while resisting water, oils, and cleaning solutions for easy wash-downs. Perfect for test labs demanding hygiene and quiet mobility, these high-temp casters deliver dependable performance and durability in high-heat, high-pressure sterilization settings.

Consult us for a load capacity rating in your application. We will need the following information: Maximum Temperature and for how long? Maximum load on each caster? Is your application wet or dry?

The above wheels with 1 1/4″ and 1 1/2″ 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 or Bronze 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.
