1. Load Capacity Test (Static & Dynamic)

Test Content

Static Load Test: Apply 1.2–1.5 times the rated load to the caster for a set duration (1–24 hours) and check for permanent deformation or cracking.

Dynamic Load Test: Run the loaded caster on a standardized test track at a fixed speed for a targeted distance to simulate real‑world moving conditions.

Test Purpose

Verify the caster’s rated load capacity; Prevent structural failure under stationary or moving weight.

2. Swivel Function Test

Test Content

Mount the caster under standard load and perform repeated 360° swivel cycles (typically 10,000+ cycles). Measure swivel torque before and after cycling to detect binding or wear.

Test Purpose

Ensure smooth, consistent steering performance; Confirm long‑term durability of the swivel bearing assembly.

3. Wear Resistance Test

Test Content

Test the wheel tread on an abrasive surface (concrete, steel plate) for a set distance. Measure tread thickness reduction, diameter change, and surface damage.

Test Purpose

Evaluate the wear life of PU, PP, PVC, or rubber wheels; Compare material durability for different application environments.

4. Impact Resistance Test

Test Content

Conduct drop impact tests using weighted weights from a specified height. Simulate obstacle impact by running the caster over a raised block at controlled speed.

Test Purpose

Validate structural strength against shocks and rough handling; Avoid sudden failure during transportation or daily use.

5. Brake Performance Test

Test Content

Measure the horizontal holding force under rated load when the brake is engaged. Conduct brake on/off cycle tests to check for fatigue, slippage, or malfunction.

Test Purpose

Ensure reliable braking on flat surfaces and inclines; Confirm brake mechanism stability after repeated operation.

6. Stem Pull-Out Test (Friction & Threaded Stem)

Test Content

For friction stem casters: measure the minimum force required to pull the stem from its socket. For threaded stem casters: test tensile strength until thread failure or bracket damage.

Test Purpose

Ensure the stem remains securely attached under stress; Validate installation stability for chair casters, trolley casters, and equipment legs.

7. Temperature Resistance Test

Test Content

Place casters in a climate chamber for 24–48 hours under high or low temperatures. Test swivel performance, load capacity, and material flexibility after exposure.

Test Purpose

Ensure stable performance in cold storage, high-temperature workshops, or outdoor environments; Identify material brittleness, softening, or degradation.

8. Corrosion Resistance Test (Salt Spray Test)

Test Content

Conduct salt spray testing per ASTM B117 for 24–100+ hours. Inspect brackets and hardware for rust, oxidation, or coating failure.

Test Purpose

Evaluate the quality of plating, painting, or stainless steel materials; Extend service life in humid, coastal, or corrosive environments.
