Finding a polyurethane AGV wheels manufacturer is easy, but finding one that truly masters high-load failure points is rare. In our 100+ OEM cases, we’ve seen countless AMR fleets in heavy-duty logistics hubs fail due to thermal stress and tread de-bonding. These aren't just minor repairs; they represent massive downtime costs in high-intensity factory automation environments.
As a specialized China source, we solve these stability issues through precision cast polyurethaneengineering. By replacing fragile injection molding with high-performance chemistry, our custom wheels consistently exceed ASTM D429 bonding standards. Whether you are an engineer designing a new robotic platform or a procurement manager seeking a reliable partner, we provide the industrial-grade durability that generic suppliers simply cannot match.
Customization Options
To maximize AGV uptime, we match Shore hardness and hub geometry to your specific floor friction and payload requirements, ensuring zero "flat-spotting" during idle charging cycles in high-intensity industrial environments.
We optimize wheel chemistry for niche environments; our polyether-based formulations prevent hydrolysis in humid warehouses, while NDI-based PU dominates high-acceleration automotive assembly lines where heat buildup kills standard rubber.
- Automotive Assembly: Supporting multi-ton chassis carriers with zero-marking performance on polished floors.
- E-commerce Fulfillment: Enhancing shuttle battery life via ultra-low rolling resistance in 24/7 sorting systems.
- Semiconductor Fabs: Specialized ESD wheels protect sensitive electronics from static discharge during transport.
- Pharmaceutical Cleanrooms: Hydrolysis-resistant PU withstands aggressive chemical washdowns and sterilization cycles.
- Cold Storage Logistics: Custom formulas that maintain grip and elasticity at -30°C without becoming brittle.
Advantages of Polyurethane AGV Wheels
Cast Polyurethane is non-negotiable for industrial AGVs; it offers 3x the tear strength of injection TPU, ensuring the wheel doesn't "chunk" when hitting floor expansion joints under full load.
- Superior Bonding Strength: We guarantee zero de-lamination, exceeding ASTM D429 standards via proprietary chemical bonding agents.
- Extended Wear Life: Tested to last 18+ months in high-traffic centers, halving your annual maintenance costs.
- High Energy Efficiency: High-rebound PU reduces drive motor torque, extending robot mission time per charge.
- Vibration Dampening: Elastic memory protects onboard LiDAR and expensive sensors from micro-shocks and floor vibration.

Case Studies
Real-world data proves that material engineering is the only way to eliminate de-bonding; our 2025 audit of a Tier-1 automotive plant showed a 65% reduction in wheel replacement labor.
Solving Delamination in 5-Ton AGVs
Client Pain Point: A logistics client faced catastrophic tread failure every 3 months using standard injection wheels.
Our Intervention: We engineered a custom NDI-prepolymer cast wheel with a shot-blasted forged steel core and thermal stabilization.
Quantifiable Result: Zero bond failures reported after 14 months of 24/7 operation, with only 0.4mm diameter wear.
Selection Guide
Step 1: Calculate Dynamic Load
Determine the total vehicle weight plus max payload and add a 25% safety factor for uneven floor loading.
Step 2: Match Hardness to Traction
Use 95A for smooth epoxy to minimize resistance; use 85A if your AMR needs more "bite" on inclines.
Step 3: Verify Hub Interface
Ensure motor torque doesn't exceed hub shear strength; we recommend keyed steel for any drive over 5kW.
Step 4: Check Environment Temperature
For high-temperature warehouses, select low-hysteresis NDI-based cast PU.
Can you re-coat our existing used AGV cores?
Absolutely. We strip the old material, inspect the core for fatigue, and re-cast. It’s 40% cheaper than new cores and prevents waste
Why mention ASTM D429? Is the bond really that different?
Yes. Most suppliers
How does Shore 95A affect AGV battery life?
Higher hardness (if high-rebound) reduces rolling resistance. Lower motor torque = longer battery runtime per charge.
What is typical service life in logistics automation?
8–12 months under 24/7 high-speed AGV operation.

That’s
Do you offer different hub materials for NDI wheels?
We cast NDI onto high-strength steel, forged aluminum, or specialized alloys depending on your weight-saving or load requirements.
How do you control your product quality?
We have 10 inspectors to carry out raw material inspection, process control ,first article inspection and final inspection.
How do you monitor the production process to avoid delayed delivery?
We use the ERP system to execute orders, and can check the order status and expected delivery time at any time.
What is warranty of products?
All of products with 3-6 months guarantee (except very frequently wearing parts).
How do you deal with after sales service?
We will response in 24 hours with solutions such as replacement or reworking.
How do you deal wtih customers' molds?
We have dedicated personnel to sort out and maintain molds regularly.
What about the lifespan of molds?
20,000 times for compressions molds and 30,000 time for casting molds.
How long can you keep customers' molds for free?
Due to the large quantity of molds, we can keep the molds for free for 2 to 3 years even if no order.
If the molds are damaged or reach the lifespan , who will be responsible for it ?
Customers only need to pay mold cost once. We will cover the cost if molds are damaged or reach the lifespan.
