Wheels for trolleys, which material is better to choose?
What material is best to choose wheels for carts
Wheels are one of the main elements of the running gear of warehouse equipment. The durability and reliability of the equipment directly depend on their correct choice. Therefore, the issue must be approached responsibly. When choosing wheels for trolleys, the material is an important parameter that affects the performance of the products.
In addition, it is necessary to pay attention to the type of construction, dimensions, the presence of the bearing and the method of installation of the support. Consider in more detail how the choice of material affects the performance of the wheel.
Which option will be optimal
There is no unambiguous answer to this question, because the choice largely depends on the operating conditions of the equipment. Today the following materials are used for production of designs:
- metal;
- polyurethane foam;
- polyamide;
- polymer metals;
- polyurethane;
- rubber.
Each of the materials has specific characteristics that determine its scope. Let's dwell in more detail on each option.
Polyurethane and its advantages
Feature of designs from this material - unique operational properties. The wheels are resistant to wear, have increased strength and do not lose performance when in contact with aggressive media (eg, solvents of organic origin, gasoline, acid and alkaline solutions).
Polyurethane has biological inertness, due to which its products are not exposed to pathogenic microorganisms. Another plus of wheels made of this material is elasticity and resistance to deformation. The product retains its shape despite high mechanical loads and unfavorable environment (extremely low or high temperature).
An important advantage is the low noise level emitted by the polyurethane wheel while driving. In addition, the material is an excellent electrical insulator.
Rubber and its features
The main advantages of the products are affordable price and versatility. The rubber wheel is ideal for moving on uneven surfaces. The material has damping properties that allow you to effectively "dampen" vibrations. Rubber retains performance at a temperature of -20 to +50 degrees.
An additional plus is the minimum noise level, which guarantees users acoustic comfort. Rubber is strong and durable. Products can be operated in almost any conditions. The material is resistant to cuts. The only disadvantage of the rubber is the fast wear, as a result of which after a certain time you have to change the rim.
Heat-resistant material that meets the requirements of fire safety is allocated to a separate group. The products comply with sanitary standards, which allows them to be used in the food industry. Other advantages of heat-resistant wheels are the following:
- resistance to temperature changes;
- ensuring reliable adhesion to the surface, including tiled floors;
- resistance to aggressive compounds;
- simple design of a wheel that guarantees ease of repair if necessary;
- increased load capacity.
Thanks to these properties heat-resistant wheels are successfully applied in various industries and life.

Polyamide and its advantages
Wheels from this material differ in durability. They do not lose their performance at elevated temperatures and in contact with alkalis. In addition, the material is resistant to mechanical damage.
Other benefits:
- resistance to sudden changes in temperature. The working temperature range of polyamide is from -20 to +80 degrees. Such properties allow to use wheels from it at the majority of productions. Exceptions are industries where there are extremely high or low temperatures. In this case it is required to apply heat-resistant models;
- no traces. Polyamide wheels do not leave marks when moving or braking sharply. This is especially true for rooms with expensive or heavily soiled floors;
- increased density. Due to this quality, the products retain their shape even in conditions of intensive operation;
- excellent load capacity. Polyamide models easily cope with the movement of goods weighing 1 ton.
- An additional plus - ease of care.
Thanks to a smooth surface of a product it is possible to clear easily and quickly of any pollution. Steam copes well with the removal of ingrown dirt.
