The climatic conditions of work environments entail the need to carefully choose industrial wheels suitable to resist to high temperatures.
It may be worthwhile to deepen the arguments concerning two macro-categories of wheels: pneumatic wheels and solid wheels, in relation to specific contexts of use.
Pneumatic wheels in the industrial sector
Pneumatic wheels are extremely adaptable products that can be used under a variety of conditions, particularly outdoor, as well as in several industrial contexts, from the mechanical engineering sector to the transport of goods. The main feature is the result of the extreme versatility of pneumatic wheels, particularly in the presence of uneven road surfaces or environments featuring obstacles of different kinds.
The advantages of pneumatic industrial wheels include:
- absorption of vibrations,
- low noise level,
- resistance to several aggressive agents,
- compatibility with delicate surfaces.
Pneumatic wheels are intended to be used with light and medium loads on several types of flooring. There are many variants of pneumatic wheels, including those made of solid rubber and in polyurethane foam, especially suitable for installation on compressors, high-pressure cleaners, concrete mixers, crate trolleys.
However, the weaknesses of pneumatic wheels include their unfitness for environments with harsh climates, particularly in the presence of high temperatures that may cause various problems, mainly due to pressure.
Risks posed by the use of wheels unsuitable for harsh environments
There is a variety of risks incurred when using unsuitable wheels in environments with extreme temperatures: effects range from tread separation from the wheel centre to the lock of rotation of brackets or ball bearings.
These inconveniences can result in different kinds of problems, from the need to frequently change wheels to the risk of trolley failure.
Solid industrial wheels suitable for high temperatures
Solid wheels include several models, with relevant brackets, suitable to be used in environments where complex industrial processes are carried out.
Below is a list of the main materials used in the production of high temperature wheels, based on the models manufactured by Tellure Rôta, a leading company in this field:
- silicone rubber,
- thermosetting resin,
- mechanical engineering cast iron,
- polyamide 6 charged with glass fibre.

Although pneumatic industrial wheels offer many advantages, especially in work contexts featuring obstacles or uneven surfaces, solid wheels are the right choice in case of harsh environments, since they can ensure a reliable performance without compromising stability and safety.
