How Small Spring Loaded Casters Are Designed


Small spring loaded casters are designed to support a small amount of weight. However, if the weight is too great, the spring may deflect, or vibrations can be excessive. Generally, five to ten pounds of weight should be sufficient. This will give you a good balance between performance and cost.

ICWM Performance Standard for Casters

The ICWM Performance Standard for Small Spring Loaded Casters is a new set of standards developed by the Institute of Caster and Wheel Manufacturers (ICWM). The new standard was developed to provide a common basis for evaluating casters and wheels. It defines industry terms, specific tests, equipment/methods, and minimum acceptable levels. As with all standards, it is subject to revision and update.

ICWM is an organization dedicated to safety, quality, and performance. They have a long history of developing and manufacturing casters. Their casters are designed to be durable and withstand various loads. Their ability to adjust weight and perform under varying conditions makes them ideal for industrial and medical environments.


Small spring-loaded casters have many applications, including for moving heavy objects. These are often used in the medical industry, where the casters must withstand the corrosive fluids found in the hospital. They should also have high load capacities, low profiles, swivel resistance, and easy operation on different floors. The most important feature of these casters is reliability and safety.

When purchasing small spring-loaded casters, make sure the springs are pre-loaded. Without the pre-load, 2000 pounds of force would be required to move an inch. The pre-load will also reduce the resistance on the caster and prevent it from restricting its movement. However, it’s important to note that if the spring pre-load is insufficient, it may not provide enough support for the load and can stress the damper.


When choosing small spring-loaded casters, look for those with a pre-load of 250 pounds or less. This will minimize deflection and reduce noise during production. Also, look for casters with a swivel or friction-free function. The pre-load of springs is also important to consider. A spring with insufficient pre-load could stress the damper, limiting the caster’s movement.

The springs on small spring-loaded casters must be the proper size to ensure a smooth and even ride. A spring that is too high can be equivalent to a spring without any deflection, while a spring with a low spring constant can extend the shock’s duration and cause excessive vibration.


Spring-loaded casters have a higher cost than other types of small casters, but their performance is superior. These casters reduce labor and material costs associated with moving equipment. Moreover, they offer smooth operation when moving sensitive equipment. They help protect the payload from damage caused by sudden shocks.

The material used in springs varies according to their uses and intended application. Some are made of steel, while others are made from alloys. Stainless steel and oil-tempered low-carbon springs are the most common, although other materials may also be used.

The triangular shape of a leaf spring is the basis for a compact cantilever. It is made by cutting strips of material and assembling them. The resulting spring has a relatively short spring length, allowing for a reduced overall height. For example, a multi-leaf spring can carry a full load in one direction but is limited in the other. In some cases, leaf separation can be overcome by clipping the leaf ends.
