Frequently Asked Questions?

1. What is your warranty policy? What if there are quality issues?

Standard warranty is 12 months. For confirmed quality issues, we provide free replacement or full refund. Each shipment includes material test reports and dimensional inspection reports.

2. How long have you been in business? What certifications do you have?

35 years in polyurethane wheel manufacturing, 52 patents, products exported to 40+ countries. We can provide ISO and ROHS certification documents upon request. OEM/ODM services available.

3. What is your minimum order quantity? How can I get samples?

MOQ: Standard products 100 pcs; custom products — please consult.
Samples: Standard products 1-3 pcs (shipping at buyer's expense); custom products — please consult.
Sample lead time: 30 days.

4. What payment methods do you accept?

T/T, L/C, PayPal. New clients: 30% deposit + 70% before shipment. Long-term clients: flexible payment terms available upon negotiation.

5. What are your typical lead times? Can you deliver on time?

On-time delivery rate: 98%+. We notify you promptly in case of force majeure.
In-stock standard products: 3-7 working days
Standard products (to produce): 25-30 working days
Custom products (new mold): 30-40 working days
Bulk orders (≥1000 pcs): 45 working days

6. Polyurethane wheel or rubber wheel — which should I choose?

Choose polyurethane when: Load ≥ 500kg/wheel, high-frequency movement, oil/chemical exposure, high noise requirements, floor protection needed, long service life required.
Choose rubber when: Load ＜ 200kg, occasional movement, pure indoor no-corrosion environment, cost priority, short-term use.

Still unsure? Ask yourself: (1) Load over 500kg? → Polyurethane. (2) Moving more than 8 hours/day? → Polyurethane. (3) Budget first? → Rubber.

7. What is the maximum load capacity and speed?

Standard series: 50kg – 10 tons/wheel, maximum 15m/s. We recommend suitable specifications based on your working conditions.

8. What temperature range do they support? Are they chemical resistant? Suitable for outdoor use?

Temperature: Standard: -20°C to +70°C; optional high-temp: +80°C; low-temp: -30°C
Chemical resistance: Oil, weak acids and alkalis; please consult for special chemicals
Outdoor use: UV-resistant coating available

9. Do you offer customization? What parameters can be adjusted?

Full customization available: outer diameter / width / hub length / bore diameter, load capacity, bearing brands (HRB, LYC, SKF, etc.), hardness (Shore A 55-95), color, special functions (high-temp resistant, oil resistant, anti-static)

10. Does higher Shore A hardness mean higher load capacity?

Yes, but with trade-offs. Higher hardness = greater load capacity, but also means reduced shock absorption, increased noise levels, and poorer floor protection. The right hardness requires balancing: load + running speed + floor protection needs. Our engineers can recommend the optimal specification based on your actual working conditions.

11. Can polyurethane wheels be used in oily or coolant environments?

Standard polyurethane is resistant to mineral oils, but ester-based oils (such as hydraulic oil) can cause erosion. For oily environments, we recommend oil-resistant formulations with enhanced bearing seals. For coolant environments, please confirm the fluid composition — we will recommend a suitable formulation based on fluid type, temperature, and concentration.

12. What information should I provide when requesting a quote?

The more details you provide, the more accurate your quote will be:
1. Application (e.g., AGV drive wheel, conveyor idler, forklift wheel)
2. Load capacity (max weight per wheel in kg)
3. Running speed (m/s or rpm)
4. Wheel dimensions (OD × width × hub length × bore diameter)
5. Bearing requirements (brand preference or ask for recommendation)
6. Order quantity (monthly usage or one-time order)
7. Working environment (indoor/outdoor, temperature, oil/chemical exposure)
8. Customization needs (new mold or modify existing mold)

13. How do I calculate the load capacity I need?

Formula: Required Load = Total Weight ÷ Number of Wheels × Duty Factor × Safety Factor (1.25)

Duty factors:
Indoor, flat floor: 1.2
Indoor with thresholds/cables: 1.5
Outdoor/uneven surface: 2.0

Example: Equipment weighing 3000kg, 4 wheels, indoor with thresholds

15. What are the main failure modes of polyurethane wheels? How to prevent them?

Five main failure modes:

Delamination: Cause: overload, impact, poor bonding. Prevention: keep load ≤ 80% of rated capacity, avoid fast passage over obstacles.
Abnormal wear: Cause: overspeed, bearing failure, debris. Prevention: speed ≤ 15m/s, inspect bearings regularly.
Permanent set (flattening): Cause: sustained static load, wrong hardness. Prevention: static load ≤ 80% rated, use higher hardness for heavy static loads.
Low-temperature cracking: Cause: wrong formulation for cold environments. Prevention: below -20°C, use Shore A 55-65 formula.
Bearing failure: Cause: lubrication failure, contamination, overload. Prevention: regular

16. What is the typical service life of polyurethane wheels?

Reference service life (standard conditions):

Light load, low speed (＜500kg, ＜3m/s): 3-5 years
Medium load (500-1500kg, 3-8m/s): 1.5-3 years
Heavy load, medium speed (1500-3000kg, 3-10m/s): 8-18 months
Heavy load, high speed (3000kg+, 8-15m/s): 4-12 months

Key lifespan factors: Load (40%) > Speed (25%) > Temperature (15%) > Chemicals (10%) > Impact (7%)

To extend lifespan: Keep load at 70-80% of rated capacity, speed at 60-80% of rated, avoid sustained static loading, inspect bearings regularly. Contact our engineers for sample testing to get accurate lifespan data for your specific conditions.
