Hard rubber caster wheels from Xiamen Yirong Hardware Co., Ltd. are engineered to deliver durability and grip for medium-duty applications, combining the resilience of rubber with added rigidity. Made from hard rubber (70-85 Shore A), these wheels offer better wear resistance than soft rubber, making them suitable for carts, furniture, or equipment that see frequent use. They support 100-800kg, withstanding the weight of office chairs, utility trolleys, or light industrial tools. The treads grip surfaces like concrete, tile, or linoleum to prevent slippage, while their moderate hardness reduces floor marking compared to soft rubber. They roll smoothly with minimal noise, enhancing comfort in offices, workshops, or retail spaces. Available in sizes 3-8 inches, with swivel or fixed designs, these wheels balance durability, grip, and floor protection, making them versatile for medium-duty mobility needs.
