CUSTOMIZED SOLUTIONS
Casters are ubiquitous in industrial production, warehousing and logistics, medical equipment, office furniture, and other fields. Different types of casters not only vary in load capacity but also in durability, service life, and applicable environments. The durability comparison between light-duty and medium-duty casters has always been a key focus for corporate procurement and equipment manufacturers. This article will provide an in-depth analysis from multiple perspectives, including material, structure, application, maintenance, and cost-effectiveness, to help you choose the right caster.

Casters are typically categorized by load capacity, installation method, and application scenario. The most common classification is based on load capacity:
Light-Duty Casters: Each wheel typically has a load capacity of approximately 40kg–150kg and are widely used in office chairs, shopping carts, and light-duty shelving.
Medium-Duty Casters: Each wheel typically has a load capacity of 150kg–500kg and are suitable for industrial carts, warehouse shelving, and equipment stands.
Heavy-Duty Casters: Each wheel has a load capacity exceeding 500kg and are commonly used in machinery and logistics equipment.
Simple structure and light weight.
Mostly made of plastic, rubber, or polyurethane (PU).
Flexible rotation makes them suitable for small equipment that is frequently moved.
Stronger structure, typically featuring a steel frame and thicker bearings.
Suitable for medium-duty cargo transport and enhanced impact resistance.
Suitable for long-term use in warehouses, factories, and medical equipment.
The material of the caster directly determines its service life.
| Material Type | Common Applications for Lightweight Casters | Common Applications for Medium-Duty Casters | Durability |
| Rubber Wheels | Furniture, Carts | Some Medical Equipment Applications | Good elasticity, but average wear resistance |
| Plastic (PP/Nylon) | Lightweight Shelves, Carts | Factory Tool Carts | Low cost, but prone to brittle cracking |
| Polyurethane (PU) | Shopping Carts, Home Furnishings | Warehouse Carts, Production Equipment | Wear-resistant, quiet, and strong impact resistance |
| Metal (Cast Iron/Steel) | Rarely used | Heavy-duty or Industrial Equipment | Ultra-high strength, but noisy |
Lightweight casters: Most often feature a simple bracket and single-layer bearing design, which can easily deform after prolonged use.
Medium-duty casters: They generally utilize a thickened steel bracket and double ball bearings, offering superior impact resistance.
Smooth indoor floors: Lightweight casters are fully suitable.
Rough floors or factory floors: Medium-duty casters are more wear-resistant and have a longer lifespan.
Chemical and humid environments: Choose medium-duty casters with anti-corrosion treatment.
According to caster supplier data:
Caster Type; Average Lifespan (under standard conditions); Average Maintenance Frequency; Service Life
Lightweight casters: 6 months to 1.5 years; Monthly inspection; Short-term use
Medium casters: 2 years to 5 years; Quarterly inspection; Long-term use
As can be seen, the lifespan of medium-duty casters is generally 2-3 times that of light-duty casters.
Lightweight casters: Suitable for static loads or minor impacts.
Medium-duty casters: Withstands larger impacts and is less likely to break or fall off.
Lightweight casters: Low unit price, but require frequent replacement.
Medium-duty casters: Higher unit price, but offer a longer lifespan and better value for money.
Recommended: Medium-duty polyurethane casters.
Reason: Long-term, high-intensity use, wear- and impact-resistant.
Recommended: Medium-duty silent casters.
Reason: Reduces noise and improves patient comfort.
Recommended: Lightweight rubber casters.
Reason: Flexible, low cost, and quiet.
Recommended: Medium-duty or heavy-duty casters.
Reason: Heavy equipment requires high load capacity and durability.
When purchasing wholesale or in bulk, choosing a high-quality caster supplier is crucial:
Does it have a comprehensive quality inspection system?
Does it offer OEM/ODM customization services?
Does it offer bulk discounts and long-term supply guarantees?
High-strength bracket design.
A variety of materials available (PU, nylon, rubber).
Strict quality inspections ensure long-term durability.

Check tire wear.
Check brackets and screws for looseness.
Regularly lubricate bearings.
Clean away dust and debris to prevent sticking.
Avoid overloading.
Avoid prolonged exposure to strong acids and alkalis.
In summary, medium-duty casters significantly outperform light-duty casters in terms of durability, lifespan, load capacity, and impact resistance. Light-duty casters are suitable for short-term, light-load scenarios, while medium-duty casters are more suitable for long-term, frequent industrial and commercial applications.
If you're looking for cost-effective, long-lasting casters, we recommend medium-duty polyurethane or steel frame casters.
