Material & Key Features

Our aluminium caster wheels feature a lightweight yet sturdy aluminium core, paired with a high-grade polyurethane (PU) tread. This design ensures:

- High Load Capacity & Shock Absorption – Ideal for heavy-duty trolleys and equipment.

- Non-Marking & Floor-Friendly – Protects delicate surfaces like epoxy and hardwood.

- Low Noise & Smooth Rolling – Perfect for indoor applications where quiet operation is essential.

Advantages & Key Considerations

Pros:

✔ Lightweight yet durable (aluminium core resists deformation)

✔ Superior floor protection (compared to metal or hard plastic wheels)

✔ Excellent load-bearing capacity for medium-duty use

Limitations:

✘ Not suitable for constant moisture (PU is prone to hydrolysis, leading to premature wear)

✘ Moderate heat resistance (avoid prolonged exposure to high temperatures)

As a leading China caster manufacturer, we prioritize quality and transparency. While our aluminium caster wheels offer outstanding performance in the right conditions, we always recommend selecting the best material for your specific environment.
