Polyurethane Travel Wheels for Semiconductor OHT

In the highly demanding semiconductor industry, where precision, cleanliness, and reliability are paramount, the performance of every component in the Overhead Hoist Transport (OHT) system matters. One critical component is the travel wheel, responsible for carrying sensitive loads across cleanrooms at high speeds with zero tolerance for vibration or particle generation. High-precision polyurethane travel wheels are the ideal solution for this specialized environment.

Stainless steel core with durable polyurethane layer

These wheels feature a stainless steel wheel core paired with a high-performance polyurethane tread. The steel core ensures excellent structural integrity and dimensional stability, even under continuous operation. The polyurethane layer, bonded seamlessly to the core, delivers outstanding wear resistance, elasticity, and longevity, minimizing downtime and replacement cycles.

ESD & anti-static performance for cleanroom compatibility

In semiconductor fabs, electrostatic discharge (ESD) is a major concern that can damage sensitive electronic components. Our polyurethane oht wheels are manufactured using ESD-safe and anti-static formulations, maintaining surface resistivity within safe limits. This ensures that static electricity is safely dissipated, supporting compliance with cleanroom safety standards.

High precision and sensitivity

These wheels are designed for ultra-precise operation, offering minimal runout, smooth rotation, and high responsiveness. Their excellent concentricity and low tolerance error allow for accurate positioning and control in automated material handling systems, crucial for wafer and chip transport processes.

Quiet and fast operation

Noise reduction is another vital factor in cleanroom environments. Our wheels are engineered to operate quietly, reducing acoustic disturbances that could interfere with sensitive machinery. At the same time, they support high-speed travel, ensuring that OHT systems maintain throughput without compromising stability.

Suitable for high cleanroom levels

Manufactured under strict contamination control protocols, these polyurethane travel wheels are suitable for cleanrooms rated iso class 5 and above. They are resistant to particle shedding, easy to clean, and free from lubricants or materials that could compromise cleanroom air quality.

Applications

These wheels are specifically designed for:

Overhead Hoist Transport (OHT) systems

Semiconductor wafer handling lines

LCD and OLED manufacturing

Cleanroom automation systems

For semiconductor manufacturers seeking durable, quiet, and high-precision motion components, polyurethane wheels with a stainless steel core offer unmatched performance. Their ESD-safe design, cleanroom compatibility, and high-speed capability make them an essential part of any advanced OHT material handling system.
