Polyurethane wheels for semiconductor OHT (Overhead Hoist Transport) systems are specially engineered for cleanroom overhead conveying, wafer handling and high-precision production lines. Combined with high-strength wheel cores and precision machining processes, high quality polyurethane materials deliver stable walking performance featuring low dust emission, high wear resistance, low noise and smooth movement in strict environments with rigorous cleanliness and vibration control. They are critical components that ensure continuous operation of automated production lines, prevent particle contamination and extend equipment service life.
Product Advantages of Semiconductor Grade Polyurethane Wheels
Adopts premium polyurethane formulations to minimize dust emission, meeting the long-term operation requirements of cleanrooms.
Excellent wear-resistant formula and rubber coating process adapt to 24/7 continuous operation, reducing replacement frequency and operation & maintenance (O&M) costs.
Precision mold forming and dynamic balance calibration ensure wheel diameter tolerance ≤ ±0.05mm, guaranteeing accurate positioning and docking of OHT carts.
Polyurethane elastomers effectively absorb impact from track joints, with operating noise below 55 dB(A) – significantly superior to metal or hard plastic wheels.
Long-term resistance to common cleaning agents and UV radiation in semiconductor factories, ensuring stable performance without degradation.

Frequently Asked Questions
Q: Do polyurethane wheels generate static electricity?
A: Polyurethane can be formulated to be antistatic or conductive on demand. If your OHT environment is sensitive to static electricity, antistatic/conductive PU options are available.
Q: How to select the appropriate hardness?
A: Hardness selection requires balancing load capacity, friction and shock absorption. Generally, softer formulations are preferred for high-speed, low-load applications (to enhance traction), while harder formulations are suitable for heavy-load or high-speed scenarios (to reduce rolling resistance).
Q: Can you provide cleanroom factory inspection reports?
A: We can provide material composition analysis, physical performance tests and factory inspection reports as required by customers to meet the audit requirements of semiconductor factories.
