How to measure Casters – Get Right Size

When choosing the right casters for your furniture, medical equipment, or industrial machinery, understanding the key measurements and specifications is essential for ensuring optimal functionality and safety. Casters are integral components in mobile solutions across various sectors. In this detailed guide, we’ll explore the crucial metrics and data points you need to consider to select the perfect casters for any application.

1. Wheel Diameter

The caster wheel diameter is pivotal for determining mobility. Larger wheels are better suited for traversing over obstacles and rough terrains, making them ideal for industrial applications and heavy-duty requirements. This measurement directly influences how smoothly the caster can navigate across different surfaces.

2. Wheel Width

Wheel width is crucial for load distribution. A wider wheel enhances the stability of your equipment and increases its capacity to handle heavy loads, making it perfect for warehouse and manufacturing settings. It ensures that weight is evenly spread across the surface, reducing wear and tear on both the wheel and the floor.

3. Load Capacity

Load capacity is a vital specification when selecting heavy-duty casters. Each caster is rated for a specific maximum weight, which should always exceed the combined weight of the load and the platform to prevent overloading. This specification is critical in high-stakes environments like hospitals and automotive industries where safety is paramount.

7. Swivel Radius

The swivel radius is important in environments where space is limited but high maneuverability is required, such as in retail spaces and hospital rooms. It determines how much space is needed to turn the caster fully around.


8. Wheel Material

Choosing the right wheel material (rubber, nylon, polyurethane, forged steel) is essential based on the environment and the type of flooring. This choice affects the caster’s noise level, traction, and suitability for either delicate surfaces like hardwood or rough surfaces in industrial applications.


9. Braking and Locking Mechanisms

Casters with brakes or locking mechanisms are crucial for applications where the equipment must remain stationary during use, such as in surgical environments or during precise operations in factories. The locking mechanism ensures stability and safety.
