What Are Rigid Casters?


Casters are very similar to traditional wheels, devices mounted to objects that someone may wish to make easily transportable. A caster attached to an object makes that object easy to roll around, much like the wheels on a suitcase or office chair.

Casters are, essentially, nothing more than a housing for a wheel and mounting brackets that enable the caster to be easily installed onto almost anything, like equipment, toolboxes, apparatuses, and more.

There are two different types of casters, known as swivel casters and rigid casters. What are “rigid casters,” and what are they used for?

The Scoop on Rigid Casters, and How to Install Them


Casters that are “rigid” are most commonly used for back and forth, straight line travel. Instead of being able to roll in any angle at 360 degrees like a swivel caster, rigid casters work the best when you need to move in one of two directions: forwards or backwards.

No matter what the type of caster, it is always held in place by “legs.” There is a leg on both sides of the wheel that sits inside the frame of the caster. This wheel is kept in place between each leg in the frame of the caster by bolts, and they are relatively simple to install.

To install rigid casters to your desired piece of equipment, all you need to do is use your mounting plate. You can either attach the mounting plate right onto the legs, forming a “U” shape for the frame of the caster to hold onto the wheel securely.

Alternatively, you could attach the casters by welding the mounting plate right onto your desired piece of equipment. The biggest majority of mounting plates typically come with four holes that would allow you to easily bolt the caster on, as well.

If installed correctly, your equipment should now be able to move forward and backward in straight lines with ease, hopefully making your workflow easier and lightening the load to make things a little easier for you and your crew.
