Wheels for industrial carts from Xiamen Yirong Hardware Co., Ltd. are engineered to meet the extreme demands of industrial environments, where carts are subjected to heavy loads, rough surfaces, and exposure to harsh substances. These wheels are constructed using industrial-grade materials: their cores are often made from cast iron or thick steel for structural rigidity, while the treads are crafted from high-strength polyurethane, nylon, or rubber compounds designed to withstand abrasion, impact, and chemical exposure. Polyurethane variants offer a unique blend of elasticity and hardness, absorbing shocks from uneven factory floors while supporting loads of up to 800 kg per wheel—ideal for carts transporting machinery parts or metal components. Nylon wheels, reinforced with glass fibers, excel in environments with oils, solvents, or high temperatures, maintaining performance in auto shops, foundries, or chemical plants. For extreme loads (over 1,000 kg per wheel), steel wheels with rubber or polyurethane coatings provide unmatched strength, withstanding the weight of large industrial equipment or bulk raw materials. These wheels feature heavy-duty bearings, often tapered roller bearings, that handle both radial and axial loads without overheating, ensuring smooth rotation even under maximum stress. Their mounting brackets are made from thick steel, welded or bolted for extra strength, and coated with anti-corrosion finishes to resist rust in humid or outdoor industrial settings. Whether used in manufacturing plants, construction sites, or waste management facilities, wheels for industrial carts deliver the strength and reliability needed to keep heavy loads moving efficiently.
