Heavy-duty casters from Xiamen Yirong Hardware Co., Ltd. are robust mobility solutions built to handle the heaviest loads and harshest conditions across industries. These casters feature reinforced steel brackets (4-12mm thick) and wheels of materials like hardened steel, cast iron, high-density polyurethane, or glass-reinforced nylon—each selected for strength and durability. They support an impressive 500-20,000kg, withstanding the weight of construction materials, industrial machinery, full pallets, and large storage units. Polyurethane wheels (90-95 Shore A) offer a balance of strength and floor protection, making them ideal for indoor industrial use, while steel wheels excel in outdoor or construction settings, resisting punctures from rocks or debris. Swivel models enable 360° maneuvering in tight spaces like factory corners or warehouse aisles, while fixed models provide straight-line stability for heavy transporters. Sealed bearings and corrosion-resistant coatings (zinc plating, powder coating) ensure performance in wet, dusty, or chemically exposed environments. Whether in manufacturing, construction, or logistics, these casters deliver uncompromising strength, ensuring heavy loads move safely and efficiently.
