Discover high-performance wear-resistant polyurethane wheels for overhead hoist (OHT) systems. Designed for cleanroom and industrial applications, these wheels offer high load capacity, low noise, excellent abrasion resistance, and long service life for efficient material handling.
Wear-resistant polyurethane wheels are a critical component in modern Overhead Hoist Transport (OHT) systems, widely used in cleanrooms, semiconductor fabs, LCD manufacturing lines, and automated material handling environments. Designed to deliver high load capacity, low noise operation, and superior durability, these wheels ensure smooth and reliable performance in demanding industrial applications.
Our polyurethane OHT wheels are engineered with advanced elastomer formulations and precision-machined cores to meet the strict requirements of high-speed, continuous-duty overhead transport systems. Compared to conventional rubber or steel wheels, polyurethane wheels offer an optimal balance of strength, elasticity, and wear resistance, significantly extending service life while minimizing maintenance.
Excellent Wear Resistance
High-performance polyurethane tread provides exceptional abrasion resistance, extending wheel lifespan even under continuous operation.
High Load-Bearing Capacity
Reinforced steel or aluminum cores ensure stability under heavy loads without deformation.
Low Noise & Smooth Operation
The elastic polyurethane layer reduces vibration and noise, making it ideal for cleanroom and precision environments.
Chemical & Oil Resistance
Resistant to oils, solvents, and various chemicals commonly found in industrial and cleanroom settings.
Non-Marking & Cleanroom Friendly
Non-shedding and non-marking properties help maintain contamination control standards.
