Heavy-duty caster wheels from Xiamen Yirong Hardware Co., Ltd. are engineered to handle extreme loads in demanding environments, combining strength with durability to ensure reliable performance. These wheels—crafted from steel, cast iron, steel-core polyurethane, or glass-reinforced nylon—support 1,000-20,000kg, withstanding the weight of industrial machinery, construction materials, or palletized goods. Treads are designed to resist wear and abrasion on rough surfaces (concrete, asphalt), ensuring smooth rolling under heavy loads. Polyurethane variants offer floor protection and shock absorption, while steel wheels provide unmatched strength for construction or mining. Precision bearings reduce friction, making movement easier even under maximum load. These heavy-duty caster wheels are indispensable for industrial, construction, and logistics applications, ensuring heavy loads move safely and efficiently.
