Frequently Asked Questions
Advantages of Heat Resistant Castors
Heat resistant castors are a specialised mobility solution, designed to perform reliably in environments with high temperatures. Built with materials and components engineered to withstand heat without compromising strength or manoeuvrability, they ensure safe and smooth movement where standard castors would degrade. Whether in food processing, bakery production, or industrial manufacturing, heat resistant castors combine durability, efficiency, and safety in challenging thermal conditions.
TENTE heat resistant castors offer various benefits:
Reliable Performance in High Temperatures - Their specialised wheel compounds and heat-resistant components prevent deformation, ensuring consistent mobility in demanding thermal environments.
Increased Efficiency and Safety - Heat resistant castors help reduce the risk of equipment failure in settings such as bakeries, commercial kitchens, and industrial ovens. By ensuring stable movement under extreme conditions, they contribute to both operational efficiency and workplace safety.
Flexible Mounting Options - Available with plate, bolt hole, and stem fittings, heat resistant castors can be adapted to a wide variety of applications without compromising on stability or manoeuvrability.
Types of Heat Resistant Castors
Heat resistant castors are available in different configurations to ensure reliable mobility under elevated temperatures, while catering to your individual application needs. The variations in wheel material, tread design, and fitting type allow you to match the castor to the thermal environment, as well as the operational load and mounting requirements.
Our Alpha stainless series is offered with robust stainless steel fixed and swivel housings. This series features two specialised heat-resistant wheel options. The first pairs a durable aluminium wheel body with a high-performance silicone rubber tread, capable of withstanding temperatures of up to 250 °C. This option offers excellent shock absorption and rolling comfort, making it ideal where vibration damping is essential. The second option is also rated for continuous use at up to 250 °C and is constructed entirely from heat-resistant thermoset plastic, both for the wheel body and tread. This variant excels in environments requiring outstanding wear resistance, delivering long service life even under demanding thermal conditions.For maximum flexibility, the Alpha Stainless castors can be configured with either a plate fitting or a bolt hole fitting, allowing seamless integration into a wide range of equipment designs.
Fields of Application for Heat Resistant Castors
Heat-resistant castors are designed for environments where elevated temperatures are part of daily operations. They are the ideal choice for bakeries, commercial kitchens, and food production facilities, where equipment is regularly exposed to hot ovens or heated surfaces. In manufacturing environments, heat resistant castors are often used on trolleys, racks, and transport carts that must pass through high-temperature zones without compromising mobility or load capacity. They are equally valuable in cold storage and freezer applications, where thermal shock resistance is essential for equipment moving between extreme hot and cold conditions. Depending on the configuration, TENTE heat resistant castors are capable of withstanding temperatures of as low as –40 °C. By combining specialised wheel materials with robust housings, heat resistant castors ensure reliable performance and safety in any setting where conventional castors would fail due to heat deformation or tread degradation.
