Caster wheel weight capacity is one important factor that is often overlooked when choosing caster wheels. It refers to the maximum weight the casters or wheels can handle. There are two types of load capacity to keep in mind: static (when the object is not moving) and dynamic (when the object is moving).
Whether you are choosing casters for new equipment or replacing old ones, it is important to consider the weight limits for caster wheels at every stage of the process. This ensures the safety and durability of your equipment. Ignoring this can lead to serious problems, especially in stationary situations.
There are many types of industrial casters, each with different weight limits. The total caster wheel load capacity can vary depending on how many casters are used on an object or if heavy-duty casters are being used.
Overloading casters can create unsafe conditions for workers and could damage your equipment or facility. So, the first step is to figure out how much weight each caster needs to support.
Once you know the required load capacity, the next step is to pick a caster that can handle that weight. In this case, you will have many options for lighter or medium loads. However, there will be fewer choices for heavier loads.
You will also need to think about the operating conditions: do you need floor protection? Is the environment exposed to chemicals, humid or sunny? These factors can limit your choices and narrow down the models available.

Weight capacity of casters refers to the maximum weight a caster can safely carry. This capacity can vary greatly depending on the caster’s type and quality. As we already mentioned in the blog above, if you choose a caster with the wrong load capacity, it can lead to equipment failure and accidents.
Therefore, it is important to carefully check the load capacity when buying industrial casters and keep a record for future reference. Industrial casters can be divided into three main categories:
Each type of caster wheel is meant for different needs, and picking the wrong one can affect safety and performance. The first step in determining how much weight each caster should support is to divide the total weight by the number of casters. For example, if a 4-wheel cart needs to support 1,000 lbs., divide 1,000 by 4, which means each caster needs to support at least 250 lbs.
But that is just the starting point! In reality, the weight might not be evenly distributed on all four casters. When the cart moves or hits a bump, the weight could shift, which, in turn, could put an extra load on fewer casters. Sometimes, a caster might top and temporarily place all the weight on just two wheels.
That is why it is important to add a safety margin and choose casters that can handle extra weight if the load shifts or impacts objects. You can select the appropriate casters after calculating the load capacity.

Casters are made up of several parts, and each one impacts the caster weight capacity. Knowing how the size, shape, width and wheel materials affect the caster will help you choose the right model from the many options available. Here is a closer look at each factor:
Wider treads help distribute weight more evenly, which increases the weight capacity of casters. In other words, wheels with wider treads can handle more weight than those with narrower treads.
If you need wheels that can support more weight but cannot increase the wheel diameter due to height restrictions, try increasing the tread width instead. The tread profile also plays a role in weight distribution- Flat treads allow them to support more weight than rounded treads by providing more surface area.
The diameter plays a big role in determining caster weight capacity. The larger the wheel, the more weight it can support. Simply put, caster wheels can support more weight as their diameter increases. Larger wheels also provide easier movement and can better handle rough surfaces and obstacles like debris or rough pavement.
The shape of the caster tread can affect its load capacity. Casters come in two main tread shapes: flat or rounded. Each type has its benefits. You can choose between a rounded or flat treat profile.
A flat tread allows the caster to support a higher load and last longer by distributing the weight over a larger surface. On the other hand, casters with rounded treads are easier to maneuver and roll more smoothly. You will need to choose the right tread profile for your needs depending on your budget and the need for easier movement.
One of the most important factors to consider is the caster wheel material. Soft casters, like those made from polyurethane, are usually quieter and easier to move. However, they have a lower load capacity than hard casters made from materials like steel, cast iron or phenolic resins.
Choosing the right caster for your specific needs can be challenging. You need to find one that meets your performance requirements, fits the available space on your equipment, suits the environment and can handle the weight of your load. That is where Muvall can help!
