What Are Caster Wheels Made Of?

Many people wonder, “What are caster wheels made of?” Steel, aluminum, polyurethane, and Neoprene rubber are just a few used materials for these parts. There are many other materials, as well. Let’s take a look at some of them in more detail. All three materials are pretty durable, but each has a unique purpose. Listed below are a few of the most common types of wheels.


Polyurethane is a synthetic rubber manufactured by combining chemical solutions and pouring them into a mold. The different manufacturing processes and starting compounds allow manufacturers to vary the properties of their end product. For example, polyurethane caster wheels are available in a wide range of hardness and resistance to chemicals, grease, and oils. As a result, polyurethane is an ideal choice for many types of caster wheels, from manual to automatic.

When choosing caster and wheels, consider the load that the wheels are required to carry. Also, if the wheels move from one room to another, they are subject to different temperatures and humidity. These changes can cause fading and wear on the reels. To avoid delamination, restrict the changes. Often, a smoother working environment is more beneficial to wheel life. But if you are unsure, check the manufacturer’s warranty to ensure you receive the best product possible.


If you need a portable solution to transport heavy loads, steel caster wheels are the perfect solution. They are designed for durability, providing mobility even on concrete surfaces. Unlike other types of wheels, they do not require surface protection, making them the perfect solution for many applications. In addition, these caster wheels are suitable for use near chemicals and heat. Read on to learn more about the benefits of steel caster wheels.

Choose steel casters if you use heavy industrial equipment. Polyolefin casters do not mark the floors. While rubber wheels are great for general industrial use, they tend to cause scratches on floors. Steel wheels are the best choice for heavy-duty equipment, which is why they are usually the most expensive. In addition, steel caster wheels are more resistant to abrasion. You can choose steel, polyurethane, or aluminum casters for different uses.


Polyurethane-coated aluminum caster wheels provide superior floor protection, non-marking treads, and quiet rolling. Compared to iron wheels, they have comparable load capacities. Moreover, aluminum caster wheels are lighter and easier to roll. Additionally, they are corrosion and rust-resistant. The aluminum hub and the 6203 precision ball bearings provide exceptional durability and rollability. The high-quality polyurethane-coated aluminum caster wheels are suitable for a variety of applications.

Urethane-coated aluminum caster wheels are suitable for environments where noise and vibration are an issue. They also have greater load capacity, resist abrasion, and are non-marking. Their high load capacity and non-slip properties make them ideal for various environments, including hospitals and schools. In addition, they are safe and non-conductive for use in harsh environments. The urethane-coated aluminum wheel is suitable for environments where people may come into contact with chemicals and other substances.

Neoprene rubber

Caster wheels are made from neoprene rubber, a synthetic compound resistant to many types of chemicals. This material forms a solid tread and is permanently molded to a hard center core. Neoprene wheels are also resistant to weather and ozone, so they are durable and won’t get sticky or brittle. Here’s a closer look at some of the advantages of Neoprene caster wheels.

Neoprene rubber casters are great for light-duty applications, such as hospital carts. They are quiet and don’t leave marks on the floors. Because neoprene rubber is highly resistant to chemicals, they are ideal for light industrial and medical applications. However, they tend to be expensive, so it’s not the best choice for many applications. Nevertheless, Neoprene rubber casters are an excellent choice for light industrial applications, such as healthcare.

Forged steel

Forged steel caster wheels have a high load capacity and are used in heavy industrial applications. These wheels are made of forged steel and have a range of load capacities ranging from 1,400 pounds to over 4,500 pounds per wheel. In addition, these wheels are incredibly durable and can tolerate temperatures ranging from -45 to over 500 degrees Fahrenheit. They are precision machined with rounded edges and are the strongest type of caster wheel available.

Forged steel provides maximum tensile strength and durability to industrial wheels. The wheels are virtually indestructible, and their load limits are controlled by their bearing capacity. These wheels also have a smooth, concentric tread, which reduces the energy required to move them around. In addition, they feature a ball check lubrication fitting for ease of lubrication. They are an excellent choice for heavy-duty industrial applications that require high-impact resistance and durability.
