What are Casters: Difference Between Casters VS Wheels

Apr 4 read


As we go about our daily lives, we encounter various pieces of equipment and furniture with wheels. However, not all wheels are created equal. Casters and wheels are two terms often used interchangeably but are actually different. This article will look at the difference between such definitions as rollers vs. wheels, as well as their various uses.

What is the difference Between Casters vs. Wheels?

A caster is a type of wheel designed to be mounted on equipment or furniture to roll and turn in any direction.

Wheels, conversely, are self-contained components that rotate around a central axis and are designed to move objects in a straight line.

The main difference between casters and wheels is that casters are a complete assembly that includes a wheel and the hardware needed to attach it to the equipment. In contrast, wheels are simply rotating circular components. The casters can also be locked in place, which provides more stability, whereas the wheels usually can’t do it.casters vs wheels

What is the difference Between Castors vs. Casters?

You may have also heard the term “castor” instead of caster. While they may sound similar, they are not the same thing.

Castor is the wheel itself, without any of the mounting hardware. Casters are the complete assembly, including the castor and the details needed to mount it to the equipment.

As mentioned earlier, the terms “castors” and “casters” are often used interchangeably, but they refer to different components. Castors are the wheel component of a caster assembly, while casters refer to the complete assembly that includes the wheel and mounting hardware.

Castors are often sold separately from caster assemblies and can be attached to various types of mounting hardware, depending on the specific application. For example, a threaded stem castor can be inserted into a threaded hole in a piece of equipment, while a grip ring stem castor can be inserted into a tube or socket.

Because castors are sold separately from the mounting hardware, they offer more flexibility and customization options than complete caster assemblies. For example, if a caster assembly is damaged, only the damaged component must be replaced rather than replacing the entire assembly.

On the other hand, complete caster assemblies (casters) offer the advantage of being a complete, preassembled unit ready to install onto a piece of equipment. It can save time and effort during installation and ensure that all components are properly matched and compatible.

What are Casters?

Casters are composed of a wheel, mounting plate, and stem and are designed to be attached to equipment or furniture to make them mobile. They can be made of various materials, including metal, rubber, and polyurethane, and come in different sizes and mounting styles.what are casters

Swivel casters, in particular, are designed to rotate 360 degrees, providing maximum maneuverability. They are ideal for equipment or furniture requiring frequent direction changes, such as office chairs. In contrast, fixed casters are more stable and provide better control. Heavy-duty casters are commonly used in industrial settings, while smaller, lighter-duty casters are used in office chairs and furniture.

When choosing casters, it is essential to consider the following:

Also, you can choose casters that blend in with your furniture.

 What are Wheels?

Wheels are round piece that roll around a central axis and is used to move objects in a straight line. They come in various sizes, materials, and shapes and can be found in various applications, from bicycles to automobiles.

Office chair wheels can be made from a variety of materials, including rubber, polyurethane, silicone, plastic, or even iron.what are wheels

Each material has its unique advantages and disadvantages, depending on the purpose of use:

With the right choice of wheels, you can enjoy comfort and smooth movement and forget about scratches and scuffs on the floor.


In conclusion, while casters and wheels are designed to facilitate movement, they are not the same. Casters are a complete assembly that includes the wheel and mounting hardware, while wheels are just circular components that rotate. Castors, on the other hand, are just wheels without any mounting hardware. When choosing between casters and wheels, it’s essential to consider the specific application and requirements. For example, swivel casters may be the best choice if your equipment moves and rotates in any direction. The choice of material and tread can also affect performance and longevity.
