What Are Casters?

If a wheel and axle make work easier by moving objects, what are casters and how are they different?

A caster is the housing to a wheel that will allow for it to be attached to the object that needs to be moved.

There are several types of casters available, but generally can be broken down into swiveling and rigid options. Swiveling casters allow for wheels to rotate freely and maneuver tight corners.

Rigid casters only allow for back and forth movement but can be turned with enough force. These are usually found on moving dollies.

Once you’ve narrowed down whether or not you’d prefer swiveling or rigid casters, there are a few other considerations to be made.

Depending on the weight of the item you’re moving, you may need Heavy Duty Casters. These casters can bear up to 15,000 lbs–which isn’t a job for the average caster from a hardware store.

Another important thing to ponder is whether or not you’ll need brakes. Although these aren’t mandatory, they can prevent any unintended rolling.
