As a maintenance personnel, equipment operator, or individual involved in selecting and using castors, you hold the key to the stability and manoeuvrability of the equipment. Your role in choosing the right diameter is crucial, and your decision should be based on your specific requirements.
Factors to Consider When Choosing a Castor Diameter

Application
When selecting a castor, consider its application: Will it be used on a trolley, a cart, or heavy-duty equipment?
Flooring
The type of flooring should also be considered when selecting castor size. Smaller castors are better suited for premium and expensive flooring applications like point-of-sale displays, while larger ones are ideal for rough or uneven surfaces.
Weight Capacity
It is crucial to consider the castor’s weight capacity. You need to pick a castor diameter that can bear the weight of the object it is being attached to and any extra weight that may be added.
Manoeuvrability
Consider how easily you need the object to move and how often you need to move it. Smaller castors provide greater manoeuvrability, whereas larger castors offer greater stability but are less manoeuvrable.
