Top 5 Suppliers Of Iron Bushing in China
Dec 30, 2025
Iron Bushing is a kind of high-performance mechanical component with iron-based materials as the core. It is made through casting, sintering or rolling processes. Some products will use low-carbon steel or stainless steel as the base plate, combined with copper powder sintering layer, PTFE lubrication layer or surface treatments such as copper plating, zinc plating and ceramic plating. It has the core advantages of high strength, wear resistance and dimensional stability. Some models also have self-lubricating properties. It is widely used in multiple fields such as automotive manufacturing, construction machinery, home appliances, textile machinery, and hydraulic equipment.
It can serve as a bearing, connecting part or protective component, playing a crucial role in supporting and fixing, reducing friction, transmitting loads, and protecting core components. It can not only adapt to harsh working conditions such as heavy loads and high temperatures, but also meet the customized requirements of different equipment through lightweight design and precise adaptation. It is an indispensable basic component in modern industrial production.
