Heavy-duty casters and wheels from Xiamen Yirong Hardware Co., Ltd. are robust mobility solutions designed to handle extreme weights and harsh conditions, combining strength with reliability for industrial, construction, and logistics applications. These components are constructed with reinforced steel brackets (4-10mm thick) and high-strength wheels—polyurethane (85-95 Shore A), nylon (glass-reinforced), or steel—capable of supporting 1,000-15,000kg. Polyurethane wheels offer a balance of strength and floor protection, ideal for factory carts moving machinery parts; steel wheels excel in construction, withstanding contact with sharp debris like nails or rebar; nylon wheels resist chemicals, suiting automotive plants or laboratories. Treads are optimized for rough surfaces (concrete, asphalt) to ensure smooth rolling under heavy loads. Configurations include fixed (straight movement), swivel (360° rotation), and braked (secure positioning) options, with sealed bearings resisting dust, moisture, and corrosion. These casters and wheels deliver the durability needed for heavy-duty operations, ensuring heavy loads move safely and efficiently.
