2 Main Components of an Office Chair Caster

office chair caster wheel

If you’re not familiar with the components of a caster, it’s easy to get confused with what we talk about here.

That’s why we’re starting with this.

There are 2 main components to all casters…

  • There’s the metal stem. This is what secures the caster to the office chair’s legs.
  • There are the wheels. Of course, they allow the office chair to move around.

When we say, “casters” we mean the whole thing, stem and wheels included.

Now that that’s out of the way, we can begin searching for the best office chair casters for you.

The Different Types of Caster Stems

When it comes to caster stems, there are 3 different types.

  • Threaded stem casters
  • Grip stem casters
  • Plate mounted casters

The threaded stem casters are like screws. You twist it into the leg’s socket to thread and secure it in.

Threaded Stem Caster Wheels

The grip stem casters are somewhat like a clip. It has a groove at the top that latches onto a ledge inside the socket.

Grip Stem Caster Wheel

The plate mounted casters are unique in that they don’t have stems. Instead, it has a plate that’s screwed in on the legs. This type of caster, however, is not common in office chairs.

How does this help you find a replacement?

Well, you’ll know what type of casters you should buy, of course!

Say, for example, your office chair has grip stem casters. You’ll know that you should avoid buying the threaded stem or plate mounted casters.

You have to make sure your replacement matches.

How to Determine the Right Stem Size

Sure, it’s easy to figure out that you need to match the new stems with the old ones…

And you can determine the type of stem with just one glance.

What’s hard is finding the right stem size.

If you look into casters, you’ll find some stems are short, while others are tall. The same goes for thickness and thinness.

If you get the wrong size, it either won’t fit at all or will be super wobbly.

To avoid that, you need to measure your old casters.

There are 2 things to measure…

  • The length of the stem
  • The diameter of the stem

Measuring the length is easy enough.

Measuring the diameter will be a lot harder, though. It’ll be confusing where the exact measurement points to.

We have a few tricks up our sleeve to help you get the exact diameter measurement.

The first one is to use a drill gauge. This is perfect since there are already exact measurements in each hole.

  • Steel drill gauge for checking fractional bit diameters

Check which hole your stem can fit through. That will be its diameter measurement.

Another trick is to use an adjustable wrench.

Secure the wrench onto the stem. Then remove the stem. From there, measure the wrench with a measuring tape or ruler.

This is a lot easier than measuring the stem’s diameter itself.

If you get these two measurements right, you’ll be able to find a replacement that fits perfectly.

The Different Types of Caster Wheels

We’ve stressed that you need to find a replacement that matches with your casters’ stem.

However, when it comes to the wheels, you can pick whatever you need or prefer.

There are so many different types of caster wheels…

But all fall under only 2 categories – twin wheels and single wheels.

Let’s take a quick look at each category and the benefits it provides.

Twin-Wheeled Casters

Twin-Wheeled Casters

These are the most common casters you’ll find in office chairs.

Since they’re so common, it’ll be so easy to find one in the markets today. There are even twin-wheeled casters with special features, such as the locking feature.

Another great thing about these casters is its double wheels. With a wider surface, it can distribute weight more evenly.

They won’t feel unstable when quickly switching directions.

If your main concern is availability and stability, then twin-wheeled casters are best for you.

Single-Wheeled Casters

Single-Wheeled Casters

What’s great about the single-wheeled casters, on the other hand, is that it’s a lot stronger.

It’ll be able to hold and withstand a much heavier person.

It also has a very solid structure with less moving parts. This makes it last much longer than twin-wheeled casters.

And, there’s no need to worry about hair getting stuck. Single-wheeled casters are high-raised, making it hard for hairs to get in.

If some do get stuck, you can easily pluck it out since single-wheeled casters have wider openings for better access.

If you’re looking for casters that have a strong build, last longer, and don’t get clogged with hair, then single-wheeled casters are a good idea.

The Different Types of Wheel Material

When replacing your casters, the wheel material you choose will play a big role.

You’ll see what we mean.

The 2 most common materials are…

  • The hard ones made from hard nylon.
  • The soft ones made from rubber or polyurethane.

What’s better?

It all depends on your flooring.

If you move your office chair across carpets, rugs, or soft chair mats, it’s best to get the hard nylon material.

If you move it across hardwood, tiles, or vinyl, it’s best to go with the soft material.

A quick tip: Just remember that soft floorings are best with hard wheels. While hard floorings are best with soft wheels.

You might be wondering, “why is that?”

It takes less force to get a hard wheel rolling because of its impact on the ground. So it won’t be difficult moving around soft carpets, rugs, and chair mats.

If you roll hard wheels on, say, hardwood, the impact will leave scratches, scuffs, and marks.

Who wants that?

The soft wheels are best for hard floors then because it minimizes the slides and scrapes on its surface.

A quick tip: If you can’t tell whether the wheel is hard or soft, try pricking it with a ballpen or your fingernail. If it dents a bit, it’s soft. If not, then it’s hard.

Depending on what wheel material you choose, it’ll be able to protect your hardwood, tiles, vinyl, carpets, rug, mats, etc..

How to Pick the Best Caster Size

What about the size of the caster?

The bigger, the better.

This is because it creates less resistance when rolling. It can overcome obstacles such as small bumps on the flooring. It’s also more durable, able to carry heavier weights, and lasts longer.

The good news is, you don’t have to get the same size as the old ones.

So if you weren’t satisfied with your old casters, you can go a size bigger on the replacements.

Say, for example, your casters are the standard size, 2in. If you want the added benefit of a bigger caster, opt for the 2.5in or 3in ones.

But, you should never get a smaller size.

If you do, it won’t be able to handle the weight and pressure of the office chair.
