Cart wheels for industrial carts from Xiamen Yirong Hardware Co., Ltd. are built to thrive in the harsh conditions of factories, workshops, and construction sites, where strength, resistance to contaminants, and reliability are essential. These wheels are constructed from heavy-duty materials: nylon or metal-core polyurethane for high load capacity (up to 1,000 kg per wheel), and steel-reinforced rubber for shock absorption in environments with rough, uneven surfaces. Their treads are formulated to resist damage from industrial contaminants, including oils, greases, coolants, and solvents—critical for carts used in automotive manufacturing, metalworking, or machinery repair shops. The wheel hubs are made from cast iron or thick-gauge steel, with precision-machined bores that accommodate oversized axles, ensuring a secure fit that resists loosening from vibration. These wheels operate well in extreme temperatures, from the cold of freezer warehouses (-20°C) to the heat of foundries (100°C), maintaining their structural integrity and rolling performance. Their tread patterns are deep and aggressive, providing traction on slippery floors (e.g., oil-spotted concrete) and preventing slippage when carts are loaded with heavy, irregularly shaped items like tooling or machine parts. By combining industrial-grade durability with performance, these cart wheels ensure that industrial carts can reliably transport heavy loads, withstand harsh conditions, and keep pace with the demands of manufacturing and construction operations.
