How to Choose Castors: Light Duty, Medium Duty, and Heavy Duty Castors

Selecting the right castors ensures smooth mobility, safety, and efficiency in various applications. Castors are categorised into three primary types based on their load-bearing capacity: light duty castors, medium duty castors, and heavy duty castors. Each type has specific applications and benefits, and choosing the right one depends on your needs. This guide will help you understand the differences and make informed decisions.

1 - Light Duty Castors:

Best For: Office furniture, small carts, retail displays.

Load Capacity: Up to 150 kg (330 lbs).

Example Applications:

• Office Chairs: Light duty castors are perfect for office chairs, where easy maneuverability and low load capacity are needed.

• Retail Displays: Retail environments often use light duty castors to allow easy movement of displays and light fixtures.

2 - Medium Duty Castors:

Best For: Medical equipment, kitchen carts, industrial trolleys.

Load Capacity: 150 kg to 500 kg (330 lbs to 1100 lbs).

Example Applications:

• Medical Equipment: Medium duty castors are suitable for hospital beds and medical trolleys, providing the right balance of mobility and strength.

• Industrial Trolleys: For manufacturing or warehouse environments, medium duty castors can handle the load while ensuring smooth movement.

Why Choose Medium Duty Castors? Medium duty castors strike a balance between mobility and load capacity. They are often made from materials like nylon or polyurethane, which offer durability and smooth rolling on various surfaces. These castors are perfect for environments where the equipment needs to be moved frequently but also must support heavier loads than what light duty castors can handle.

3 - Heavy Duty Castors:

Best For: Warehouse carts, machinery, heavy industrial equipment.

Load Capacity: 500 kg to 2,000 kg (1100 lbs to 4400 lbs) or more.

Example Applications:

• Heavy Machinery: Heavy duty castors are essential for moving industrial machines that are both heavy and difficult to maneuver.

• Warehouse Carts: In logistics and warehouses, these castors handle the transport of heavy pallets and goods over long distances.

Why Choose Heavy Duty Castors? Heavy duty castors are built to withstand high loads and harsh environments. Often made from steel or reinforced materials, these castors ensure the safe and efficient movement of extremely heavy equipment. They are typically designed with strong bearings and heavy-duty mounting plates to handle the stress of industrial applications.

How to Choose the Right Castor for Your Needs

When choosing castors, consider the following factors:

1. Load Capacity: Determine the total weight the castor needs to support, including the weight of the equipment and any additional load.
2. Environment: Consider the surface and conditions where the castors will be used. Light duty castors are best for smooth indoor surfaces, while heavy duty castors are designed for rough and uneven terrain.
3. Frequency of Movement: If the equipment will be moved frequently, choose a castor that balances ease of movement with the necessary load capacity.
4. Material: The material of the castor affects its durability, noise level, and floor protection. For example, polyurethane is quiet and non-marking, making it ideal for indoor use.

Choosing the right castor—whether light duty, medium duty, or heavy duty—is essential for ensuring the efficiency and safety of your operations. By understanding the specific needs of your application and considering factors like load capacity, environment, and frequency of movement, you can select the perfect castors for your requirements.
