What Are Caster Wheels Used For

A caster (also castor according to some dictionaries) is a wheeled device typically mounted to a larger object that enables relatively easy rolling movement of the object. Casters are essentially special housings that include a wheel, facilitating the installation of wheels on objects.

What is difference between caster and wheel?

The wheel is limited in that it only spins on a single axis. It can only roll in one direction at a time. Casters incorporate wheels into their designs, but they are a bit more sophisticated. A caster includes the mounting system that holds the wheel in place.

Why is it called a caster wheel?

As the center hub of the wheel revolves around the center of the swivel section it is said to “cast” in that small circle. Thus, caster! This essential swiveling feature of casters makes it so much easier to move heavy loads and turn tight corners in a warehouse.
