According to the material used for casters, they can be divided into many types, among which polyurethane wheels and rubber wheels are quite similar, and sometimes it is difficult to distinguish them solely based on their appearance. So, which is better, polyurethane wheels or rubber wheels?

Overall, polyurethane wheels are better, and there is a trend of polyurethane wheels replacing rubber wheels. Why are polyurethane casters better? Because polyurethane casters have some advantages over rubber casters, which are reflected in the following aspects.

1. Service life: Polyurethane casters usually have a longer service life and are more wear-resistant, which reduces the cost of use.

2. Load bearing capacity: The load-bearing capacity of polyurethane casters is much greater than that of rubber casters, and is several times more than that of rubber casters, because polyurethane casters have better pit crack growth and tear resistance.

3. Environmental Protection: Polyurethane, as an artificial material, does not require a large amount of rubber raw materials, making it more environmentally friendly.

4. Rolling resistance: Because the chemical structure of polyurethane material determines that it has less rolling resistance than rubber, the added thrust is smaller and more labor-saving.

Although polyurethane wheels are superior to rubber wheels in many aspects, rubber wheels also have their own advantages, so they have not been completely replaced. For example, rubber casters are softer, more comfortable, and have better cushioning ability.
