This solid self-lubricating copper sleeve embedded with PTFE combines the wear resistance ...
The PTFE single-flange solid self-lubricating copper sleeve is a high-performance mechanical component. It is made by embedding PTFE (polytetrafluoroethylene) solid lubricating material onto a high-strength brass base. It features high strength, high hardness, wear resistance, and chemical corrosion resistance. It also has an extremely low friction coefficient and excellent water lubricity. The operating temperature is below 300 degrees Celsius. It is suitable for water and seawater lubrication, such as in ships, water control valves, water turbines, pharmaceutical and beverage machinery, etc.
