Introduction

图片1.png

Tread: The high-quality polyurethane elastomer cast through chemical reaction has A hardness of 93±3 Shore A. It has low walking noise, small rolling resistance, protects the ground, is highly wear-resistant, has high resistance to cutting and tearing, leaves no marks, does not stain, and has an excellent bonding effect with the wheel core.

Wheel core: Metal materials such as 45# steel, cast iron, die-cast aluminum alloy, and stainless steel can be selected according to the working conditions. Surface treatment options include painting, phosphating, galvanizing, Dacromet, etc

Other features: Resistant to corrosion by various corrosive substances; Operating temperature: -30°C to +70°C, short-term up to +90° C. Load capacity decreases above +40°C

Frequently Asked Questions?

1. What are the advantages of polyurethane-coated wheels compared to other materials (e.g., rubber, plastic, or metal)?

The advantage of polyurethane lies in the fact that by adjusting the polyurethane formula, one can change its hardness, color, friction coefficient, etc., to achieve the effects of noise reduction, anti-static, and ground protection. Its long lifespan and low maintenance costs make it have a high overall cost-effectiveness. Various environments can be used, such as food-grade (without pollution), conductive-grade (for electronic workshops), and high-load (for port equipment).

2. What is the load capacity and maximum speed of your polyurethane wheels?

We can customize the corresponding polyurethane wheels according to your requirements. Under normal circumstances, the maximum load can reach 10T and the maximum speed can reach 10 kilometers per hour.

3. Are your wheels resistant to oil, chemicals, extreme temperatures, or UV exposure?

Yes, we can adjust the polyurethane formula to meet different requirements.

4. What is the hardness range (Shore A/D) of your polyurethane coatings? How does it affect performance?

The hardness range of polyurethane materials usually falls between Shore 70A and Shore 100D. High-hardness polyurethane materials have better load-bearing capacity and wear resistance, while low-hardness polyurethane materials offer better ground protection and noise reduction effects.

5. Can you customize wheels based on specific dimensions, colors, or hardness requirements?

All the parameters can be customized according to your needs.

6. What types of cores (e.g., aluminum, steel, plastic) do you support for coating?

We support e.g., aluminum, steel, nylon cores

7. What is your minimum order quantity (MOQ) and lead time?

The minimum order quantity is 10 pieces. The delivery time is usually 25 days.

8. Do you provide samples? Are they free or charged?

We support the proofing process, but we require you to pay the corresponding fees.

9. What is your warranty policy for polyurethane wheels?

If delamination or cracking occurs within 24 months, we will provide a free replacement.
