High Temperature Phenolic Wheels have a prefix โTPโ 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 475ยฐF for continuous use. Then allow to cool to room temperature.ย 525ยฐF for intermittent use.ย If used above 475ยฐ F for more than 30 minutes continuous operation it will reduce the life of the wheel.
High Temperature Wheels with a prefix โNPโ 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 425ยฐ F for 30 minutes MAXIMUM continuous operation. Then allow to cool to room temperature. If used above 425ยฐ 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.
High temperature wheels with a prefix of โOVโ are made of Epoxy mixed with glass fiber. They perform best in both moist heat and dry heat appllications. Temperature Range: UP to 460 degrees Fahrenheit for 60 minutes MAXIMUM continuous operation.
The High Temperature Phenolic Wheels ( prefix โTPโ ) , the High Temperature Glass-Filled Nylon wheels ( prefix โNPโ ), and the High Temperture โOVโ Epoxy Resin 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. 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 1/4โณ and 1 1/2โณ tread width have plain bores and a bushing(s) to fit onto a 3/8โณ axle. Wheels with a 2โณ tread width have a 3/4โณ ID Roller Bearing or Bronze Bearing and come with a steel spanner bushing to fit onto a 1/2โณ axle. Some sizes are available with a 3/4โณ Plain Bore upon request.
Sterilizer wheels have a prefix โHTRโ 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. 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 3/8โณ axle. The 5 x 2 wheel has a bronze bearing and fits on a 1/2โณ axle.
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 250ยฐF for 15โ20 minutes or 29 PSI at 273ยฐF for 6 minutes, as well as steam retorts up to 300ยฐF. 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.
Our 2-inch wide high heat caster retort wheels are expertly designed for smooth-surfaced food processing environments, constructed from heat-stabilized, glass-reinforced polypropylene with a durable 85D durometer. Capable of withstanding temperatures up to 300ยฐF, these high temp casters are perfect for steam retorts, autoclaves, and rigorous steam-cleaning in meat packing facilities and commercial kitchens. Their white finish highlights dirt for easy hygiene monitoring, and the rounded tread ensures smooth, low-effort rolling on flat surfaces, supporting loads up to 900 lbs. These lightweight, non-marking wheels resist cracking and chipping, offering outstanding reliability in high-heat conditions.
Built for wash-down and steam retort applications, these high temp caster wheels repel oils, petroleum, salt solutions, acids, solvents, and cleaning agents, maintaining performance in harsh, high-temperature settings. Compared to standard polyolefin wheels, they provide enhanced heat and chemical resistance, making them a superior option for facilities requiring strict sanitation and durability on smooth floors. Our high heat caster retort wheels deliver effortless mobility, ensuring compliance with hygiene standards and operational efficiency in demanding food processing environments, including high-heat steam retort systems.
You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
