When it comes to selecting the ideal castor wheels for your equipment or applications, one of the critical factors to consider is load capacity. Ensuring that your castors can safely support the weight they will bear is essential for smooth and efficient operation. In this blog post, we'll guide you through the process of choosing the right load capacity for your 100mm to 150mm castor wheels, helping you make an informed decision that aligns with your specific needs.

Understanding Load Capacity

Load capacity refers to the maximum weight that a castor wheel can support while maintaining its performance and durability. Exceeding the specified load capacity can lead to premature wear, reduced manoeuvrability, and potential safety hazards. Here's how to determine the right load capacity for your 100mm to 150mm castor wheels:

1. Evaluate Your Load:

Begin by assessing the weight of the equipment or load that the castor wheels will bear. This includes both the static weight (when stationary) and the dynamic weight (when in motion). Be sure to consider any potential variations in load.

2. Factor in Safety Margins:

It's advisable to incorporate safety margins into your load capacity calculations. Safety margins provide an extra buffer to account for unexpected surges in weight or uneven weight distribution, ensuring that your castor wheels operate safely and reliably.

Choosing Load Capacity for 100mm to 150mm Castor Wheels

The load capacity you require for your 100mm to 150mm castor wheels depends on several factors, including the application and load conditions. Here's a general guideline to help you make the right choice:

1. Light-Duty Applications (Up to 300kg):

For light-duty applications such as office furniture, medical carts, or lightweight trolleys, 100mm to 150mm castor wheels with a load capacity of up to 300kg are typically sufficient.

2. Medium-Duty Applications (300kg to 600kg):

In applications that involve moderate loads, such as industrial carts, material handling equipment, or mobile cabinets, opt for castor wheels with load capacities ranging from 300kg to 600kg.

3. Heavy-Duty Applications (Over 600kg):

For heavy-duty applications like machinery, equipment stands, or large trolleys with substantial loads, choose 100mm to 150mm castor wheels with load capacities exceeding 600kg to ensure stability and longevity.

Consult the Experts

If you're uncertain about the load capacity requirements for your specific application, it's advisable to consult with experts or suppliers who can provide tailored recommendations based on your unique needs. They can take into account factors such as the frequency of movement, terrain, and environmental conditions to help you select the right castor wheels.


Choosing the correct load capacity for your 100mm to 150mm castor wheels is a critical step in ensuring the longevity and performance of your equipment or applications. By evaluating your load, factoring in safety margins, and considering the application's demands, you can confidently select castor wheels that meet your requirements and provide reliable support.
