How To Choose The Right Casters

Posted by Schaumburg Specialties on Apr 24, 2020

When we think of caster wheels, we don’t give them much thought. However, when you go out to buy a caster wheel, you realize how much you need to learn.

For caster wheels, especially industry caster wheels, there are a number of things that need to be considered. These range from the floor type caster wheel will be used on to the load size it will have to bear.

But before going into those details, first, we need to know what a caster wheel is!

What is a caster wheel?

Casters, or more commonly known as caster wheels, consisting of an assembly that has a wheel and a bracket and are attached to a larger body in order to move that body around.

So simply put, a caster wheel is a part that moves a shopping cart when you push it. Caster has a wheel and a bracket, and the bracket is attached to the body with screws or some other thing.

Now that we know about caster wheel basics let’s jump to our main concern.

How to Choose the Right Caster

As we mentioned before, choosing a caster wheel is a bit more complicated than it seems, but we will try to deconstruct it for you. Below we will discuss 5 things that one needs to take into consideration before buying a caster wheel.

So without further ado, let’s get started!

Load Weight

A castor wheel is made to move things around, usually heavy loads. This is particularly true for industrial caster and wheel because in industries heavy stuff is usually on the move. So for industry casters, you need a wheel that is thick enough to bear that pressure and doesn’t break under it.

One way to choose the right caster wheel, in case of load weight, is to divide the total weight by the number of caster wheels. You will get the load on a single caster wheel which should guide you about the thickness of the caster wheel.


Wheel size depends upon many factors, including the load weight. It should be obvious that the greater the load weight, the bigger the wheel size and vice versa.

However, there is a slight problem in that math. You can’t keep on increasing the size of the tire indefinitely to meet the load weight requirements. If wheel size increases beyond a certain point, the body (cart) will become unstable and topple very easily. This is because the center of gravity has been shifted up due to a larger caster wheel size.

Wheel Bearings

Wheel bearings are an important part of the castor wheel and need to be chosen very carefully. Otherwise, the whole system may halt because you chose the wrong bearing which broke under pressure.

There are several types of wheel bearings, each suited for specific requirements.

  • Plain Bearing: Plain bearing or sliding bearing can be used in areas where the load is relatively light and easy to move around
  • Ball Bearing: Such a bearing is used in places where extra help from the rolling balls can help move the body around with much less effort. However, ball bearings are subject to greater wear and tear than the plain bearing.
  • Roller Bearing: If you are looking for the strength of a plain bearing and the ease of a ball bearing, roller bearing should be your choice. It can withstand more pressure than ball bearings and is easier to roll than the plain bearing. It is being used in industrial casters.

These were some of the most commonly used wheel bearing types. There are many more wheel bearings that can also be used for their particular features.

Floor-type heavily influences the choice of the caster wheel. If you’re going to use a caster wheel on a hard and smooth surface, you should go with soft tread wheels. On the other hand, hard tread wheels are recommended for softer surfaces as they roll better on such surfaces.

In addition to the rolling factor, floor protection is also to be considered. In case of a carpeted or other soft surfaces, never go with steel or cast iron wheels. They will wreck the floor. You need to go with high modulus rubber wheels which will be easy on the surface. While, in case of industrial casters, steel or iron wheels work great because they can bear the pressure without bending or breaking.

Extreme Climates

If you are working in extreme climates, you need to choose the right caster wheels for that, or you will be stuck with something that won’t work at all.

Choosing the right caster can be a bit too much. However, Schaumburg Specialties has got you covered with the best casters that meet every one of your requirements perfectly. Contact us today to get the caster you need
