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.

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

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

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)

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.

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.

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)

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

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.

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

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.
