Heavy-duty polyurethane (PU) trolley wheels from Xiamen Yirong Hardware Co., Ltd. combine the strength of heavy-duty design with the performance benefits of polyurethane, making them ideal for demanding applications. These wheels feature a thick, high-density PU tread that offers superior wear resistance and load-bearing capacity, capable of supporting heavy loads in industrial, warehouse, and logistics settings. PU’s inherent elasticity reduces vibrations, ensuring a smoother ride even over rough surfaces, while its low rolling resistance minimizes the effort needed to move loaded trolleys. The material is also resistant to oils, chemicals, and abrasion, maintaining performance in harsh environments. Paired with sturdy metal brackets, these wheels provide stability and durability, making them suitable for heavy machinery transporters, large logistics carts, and industrial material handlers.
