CUSTOMIZED SOLUTIONS
In the industrial and commercial sectors, casters, as essential moving components, are widely used in a variety of industries, including logistics, furniture, medical equipment, and warehousing. Medium and light-duty casters, due to their moderate load capacity and high flexibility, are the preferred choice in many applications. However, accurately testing the quality of medium and light-duty casters to ensure stable performance, safety, and reliability is a critical step in the procurement and use process. This article details quality testing methods for medium and light-duty casters from multiple technical perspectives, helping buyers and users identify high-quality products.

Medium and light-duty casters generally refer to casters with a load capacity between 50kg and 300kg, suitable for most small and medium-sized equipment and furniture. Depending on the application environment, casters can be categorized as fixed casters, swivel casters, and casters with brakes.
Wheel core: Typically made of materials such as polyurethane, rubber, and nylon, it determines the caster's load-bearing capacity and wear resistance.
Bearing: Ensures smooth rotation of the caster, typically using ball bearings or bushings.
Bracket: Typically stamped or cast from steel plate, it determines the mounting method and strength.
Fixtures: Provide additional functions such as brakes and positioning.
Due to their diverse application scenarios, the quality of medium- and light-duty casters directly impacts the mobility and safety of equipment. Poor-quality casters can cause equipment to become difficult to move, produce excessive noise, or even lead to safety accidents. Therefore, rigorous quality testing is essential to ensure product performance.
Load-bearing capacity is a core indicator of caster quality. Testing is typically conducted on a standard test bench, with load gradually applied to observe the caster for deformation, damage, or abnormal rotation.
Table 1: Classification of Light and Medium-Duty Caster Load Capacity
| Caster Type | Rated Load (kg) | Applicable Applications |
| Light Duty | 50-100 kg | Furniture, Light Carts |
| Medium Duty | 100-300 kg | Equipment, Tool Carts, Medical Carts |
The test focuses on wheel deformation, bracket stress, and bearing capacity.
Rotational flexibility is related to the ease of equipment operation. This test measures the caster's 360° rotation resistance and rolling resistance.
Test Tool: A torque meter measures the torque during rotation.
Standard: High-quality casters should maintain rotational resistance within a reasonable range to ensure smooth pushing and pulling.
Wear Resistance Testing
The wear resistance of the caster wheel surface material is tested through wear tests simulating actual use environments.
Common Methods: Sandpaper abrasion test and roller friction test.
Result Evaluation: Amount of wear and degree of surface change.
Corrosion Resistance Test
Salt spray testing is performed on the metal bracket to evaluate the caster's corrosion resistance in humid and corrosive environments.
Noise Test
The noise level produced by casters during use is a key indicator of user experience. The test environment requires a quiet environment, using standard equipment to measure the decibel level produced by the caster at a specific speed.
| Caster Material | Average Operating Noise (dB) | Notes |
| Polyurethane | 50-60 | Suitable for quiet environments |
| Rubber | 55-65 | Good cushioning properties |
| Nylon | 60-70 | Suitable for hard floors |
Includes high and low temperature testing, waterproofing testing, and chemical corrosion resistance testing to ensure the caster can function properly in various environments.
Different wheel core materials determine the performance and environmental suitability of the caster.
| Materials | Features | Applicable Environments | Disadvantages |
| Polyurethane | Wear-resistant, low-noise, oil-resistant | Suitable for industrial workshops and hospitals | Highly expensive |
| Rubber | Good cushioning and quiet | Suitable for offices and light industry | Poor wear resistance |
| Nylon | High hardness and load-bearing capacity | Suitable for outdoor use, on hard surfaces | Loud noise and noticeable vibration |
Steel brackets are strong and suitable for carrying heavy loads. Aluminum alloy brackets are lightweight and rust-resistant, but are more expensive. Stamping and casting processes affect the durability of the bracket.
