What Is The Difference Between A Caster And A Wheel?

The main difference between a caster and a wheel lies in their design and functionality.

A wheel is a simple, circular device typically made of materials such as rubber, plastic, or metal, designed to rotate on an axle. It is commonly used to facilitate movement or transportation by rolling over a surface.

On the other hand, a caster is a more complex assembly that includes a wheel but also incorporates a mounting system, such as a fork or a plate, that allows the wheel to swivel. This design enables the caster to facilitate multidirectional movement, making it ideal for use in applications where maneuverability is important, such as in furniture, carts, or industrial equipment.

In summary, while a wheel is a single component designed for rolling, a caster is a complete assembly that includes a wheel and mounting system, allowing for greater mobility and maneuverability.
