Description
Custom ESD Safe PU Wheels for Semiconductor Factories
Why Choose This Product
As a top ESD-safe PU wheel manufacturer in China, we build products for environments where static discharge can damage sensitive electronic components. The conductive polyurethane layer maintains surface resistance within the 10⁴–10⁶ Ω range, so static charges are grounded safely through the bearing and bracket instead of arcing unexpectedly. The aluminum hub and precision bearing system reduce vibration, improve positioning accuracy, and extend equipment service life.
Over ten years of production experience and thousands of wheels sold into demanding cleanroom and semiconductor facilities give you a reliable track record backed by real-world evidence. Typical applications include AGV transport systems, conveyor lines, wafer handling equipment, and automated assembly stations where ESD control is critical.

Details Images – Construction & Application
The close-up views below show the ESD-safe PU tread, precision hub, and mounting interface used in our wheel range. These construction details help buyers verify fitment and understand how the wheel is built for cleanroom and automated production environments.
Material Properties – Conductive PU Compound
| Property | Test Result | Customer Benefit |
|---|---|---|
| Hardness (Shore A) | 92° | Balanced traction and low rolling resistance |
| Surface Resistance | 10⁵ Ω | Safe static dissipation in cleanrooms |
| Tensile Strength | ≥ 25 MPa | High durability under repeated heavy loads |
| Abrasion Loss | ≤ 0.05 cm³ / 1.61 km | Longer service life and lower replacement cost |
| Impact Resistance | Pass 5 J drop test | Reliable performance under impact conditions |
| Temperature Range | -30°C to +80°C | Stable operation in varied climates |
These measured values represent typical performance for our ESD-safe conductive PU compound. The combination of high tensile strength and low abrasion loss translates directly into longer wheel life and reduced replacement frequency in continuous production environments. Custom hardness from Shore A 85° to 95° is available from our factory.

Frequently Asked Questions – ESD-Safe PU Wheels
1. How do your Custom ESD Safe PU Wheels for Semiconductor Factories prevent electrostatic discharge?
Our ESD Safe PU Wheels use a conductive polyurethane tread that holds surface resistance between 10⁴ and 10⁶ Ω. Static charges are safely directed through the wheel, bearing, and bracket to the ground, preventing sudden discharge that could damage sensitive semiconductor components.
2. Can I customize the wheel diameter, load capacity, and hub material?
Yes. We provide full OEM/ODM customization for diameter, hub material, hardness, color, and bearing type. For high-load AGV applications, we recommend a steel hub version with dynamic balancing tested to ≤0.05 mm.
3. What are your standard MOQ and delivery time?
The standard MOQ is 50 pieces for regular sizes, and sample orders are always welcome. After sample approval, delivery usually takes 15 to 25 working days depending on quantity and current production load.
4. Do your wheels meet cleanroom and ESD certification requirements?
Our wheels are ISO9001 and RoHS compliant, and we can provide SGS test reports covering surface resistance, load, and abrasion. If you have a specific cleanroom class or ESD standard in mind, please share it and we will validate the solution before shipping.
5. What is the best way to package and ship ESD-safe PU wheels?
We pack wheels in export-standard plywood pallets or cartons with anti-static film and protective corner padding. Shipping can be arranged by sea, air, or express, and we will handle export documentation for your destination market.
6. Can your engineers help me choose the right wheel for my AGV or conveyor system?
Absolutely. Share your working load, floor surface, speed, and electrostatic requirements, and our team will recommend the most suitable size and formulation at a competitive price for your market.
