PU Wheels
Heavy-duty cast polyurethane tyred wheels designed for Automated Guided Vehicles (AGVs), electric warehouse forklifts, monorail overhead conveyors, and theme park rides. Engineered with proprietary NDI/MDI elastomers to eliminate flat-spotting and thermal buildup under high cyclic speeds.
Types & Configurations of PU Wheels
AGV & Autonomous Robot Drive Wheels
High-traction, low rolling resistance polyurethane tires directly bonded to precision servo-motor hubs.
Electric Forklift Drive & Load Wheels
Heavy-duty 93A/95A Shore A cast wheels engineered for reach trucks, order pickers, and pallet stackers.
Overhead Monorail Trolley Wheels
Flanged polyurethane wheels guiding heavy automobile assembly body carriers.
Heavy Industrial Castor Wheels
Fabricated steel swivel castors fitted with heavy polyurethane wheels for 10-ton machinery dollies.
Guide & Stabilizer Wheels
Small diameter high-speed polyurethane wheels stabilizing automated elevator counterweights.

Material Selection & Properties
We offer specialized compound formulations tailored to chemical media, thermal extremes, static deflection, and dynamic fatigue requirements. The best material depends on your operating environment and required service life.
| Material / Polymer | Key Engineering Properties | Recommended Applications & Considerations |
|---|---|---|
| Cast Polyurethane 70A - 95A | 5x higher abrasion resistance than rubber, high load | Forklift drive wheels, heavy slurry scraper blades |
| Hydrolysis-Resistant PU (Ether) | Resists microbial attack, wet environments & water | Marine guide rollers, wastewater treatment scrapers |
| High-Resilience PU (Ester) | Superior dynamic spring properties, tear strength >60 kN/m | Die-spring blocks, metal-stamping cushions |
| Food-Grade Polyurethane | FDA 21 CFR 177.2600 compliant, oil & fat resistant | Bakery dough rollers, meat processing conveyor scrapers |
| Antistatic PU (ESD) | Surface resistivity 10⁶ - 10⁹ Ω/sq prevents sparking | Automated warehouse AGV wheels, paint-line rollers |
