The iron-core polyurethane wheel is an industrial wheel featuring a metal core as its structural backbone, encased in a polyurethane (PU) outer layer. Its key innovation lies in the synergistic combination of the metal core’s robust load-bearing capacity and the polyurethane layer’s superior performance characteristics. The metal core ensures that the wheel maintains its shape under heavy loads, with individual-wheel load capacities reaching several tons; meanwhile, the polyurethane coating delivers exceptional wear resistance, outstanding shock absorption and noise reduction, and excellent resistance to oil, grease, acids, and alkalis. Operating reliably across a wide temperature range from –40°C to 80°C, this wheel is gentle on flooring surfaces and minimizes the risk of scratching. Owing to its high load capacity, ultra-high wear resistance, and smooth, quiet operation, the iron-core polyurethane wheel is widely used in logistics and warehousing, industrial production lines, mining and metallurgy, and medical equipment—making it a dependable and durable locomotion component for heavy-duty material handling and automated systems.
