There are dozens of wheel and material options available to you in your caster journey, and two of the most popular across the industry are poly (short for polyurethane) and classic rubber.
Understanding the differences between these can be an essential step in helping you determine whether poly wheels or rubber wheels will best suit your needs.
Polyurethane caster wheels, often referred to as simply poly wheels, offer several unique benefits in the workplace. These include:
Our tread formulation designed to achieve optimal ergonomic benefits; ErgoTread returns energy, reducing initial and continuous push-pull force. ErgoTread also resists debris, is quieter, and won’t mark floors.
The hardest durometer polyurethane we offer, shore 70D, is designed to maximize weight capacity. This extra-hard polyurethane is ideal for heavy loads, with non-marking and wear-resistant properties.
Despite the numerous benefits afforded by poly wheels, there are some cases in which pneumatic rubber wheels are the best option.
Using this type of wheel occurs when you need to move loads outdoors or across very uneven surfaces, including over gravel or cracks in the flooring. Rubber wheels are far better suited to outdoor-only applications and are used extensively in the construction and air-ground support industries, especially.
The pneumatic tires cushion the load and roll over obstructions with ease. These casters provide longer wheel life, less maintenance, and high shock absorbency. Keep in mind that even when used as indicated, rubber wheels will not wear as well as poly casters, which means you will need to replace them more frequently.
