Different Types of Wheels Used for Heavy Duty Industrial Caster Applications

Different Types of Wheels Used for Heavy Duty
Industrial Caster Applications
At their very core, casters are high-strength steel wheels in various styles designed to withstand challenging
environments despite the heaviest of loads. Part of choosing the very best caster for your company’s needs involves
starting with the right wheel, and the following are some of the most popular options.
Forged Steel
When it comes to load capacity, only forged steel will withstand the weight. These fine-grain wheels provide incredible
impact resistance, and they roll with ease. Forged steel wheels paired with tapered bearings provide a smooth ride for
loads of all weights and sizes.
Flanged
Flanged wheels are available in single and dual styles, and they are perfect for moving loads along a fixed rail. These
wheels are constructed of steel and cast iron to provide the longest possible lifespan and incredible strength, even
under immense weight.
Polyurethane
Polyurethane wheels support more weight than rubber, and they last longer at the same time. Unlike steel or even cast
iron, a polyurethane wheel offers a slight bit of give, so it won’t cut into or damage your floors when carrying a heavy
load. Liquid-cast wheels come in various types and sizes, as well.
NyTec-MD
NyTec wheels are incredibly durable, and quality testing shows they can handle about 80% of the weight as a steel or
iron caster. When a specific industry requires casters in a facility that may cause exposure to chemicals or moisture,
NyTec offers some of the best corrosion resistance in the industry, and it is virtually maintenance-free.
Phenolic Resin
Like NyTec, a phenolic resin wheel offers nearly the same load-bearing potential as steel or iron, but is more cost
effective. These wheels provide superior rollability and do not damage floors despite the loads they carry.

Pneumatic
For situations in which shock absorption is important to load movement safety, a pneumatic wheel is a phenomenal
option. These wheels offer more absorption and cushioning than many of their counterparts, but no spring is required.
This makes pneumatic wheels a cost-effective alternative to spring-loaded casters, but it should be noted that loadbearing
capabilities are a bit more limited since the wheel is quite a bit softer than other types.
Cast & Ductile Iron
Cast iron wheels are designed for applications when high heat is a factor, such as in a foundry. These are made from
Class 30 gray iron which is durable and complete with heavy-duty cross sections. Ductile iron wheels are much like cast
iron, but is stronger to resist chipping and breaking.
Drive & Keyway
Drive and keyway wheels are designed to work with computerized drive systems and come in a variety of shapes and
sizes. They range in diameter from 3” to 18” and also come in several unique bore sizes to suit all applications.
The perfect caster starts with the perfect wheel, and as you can see, different wheels are better suited for certain
applications. Learning more about the qualities and benefits of each wheel type can help you make better decisions
about your unique needs.
