When it comes to bushings designed for high-temperature environments, a customized approach often yields the best results. POM (Polyoxymethylene), also known as acetal or polyacetal, is a thermoplastic polymer that exhibits excellent mechanical properties, dimensional stability, and resistance to chemicals, making it a suitable choice for self-lubricating bushings in demanding applications.
Customized POM bushings are tailored to meet specific requirements, such as size, shape, load capacity, and operating temperature. Their self-lubricating properties ensure smooth operation with minimal friction and wear, even under extreme conditions. This is achieved through the use of special additives or coatings that enhance the material's lubricity.
In high-temperature environments, POM bushings demonstrate exceptional thermal stability, maintaining their mechanical properties and dimensional accuracy even at elevated temperatures. This allows them to perform reliably in applications such as engines, turbines, and other heavy-duty machinery.
The customization process typically involves detailed consultation with the customer to understand their specific needs and requirements. Based on this information, the bushings are designed and manufactured using advanced techniques and precision equipment. The resulting product is a high-performance, reliable bushing that is ready to meet the challenges of even the most demanding high-temperature applications.

Marginal Pb-free self-lubricating bearing is used steel-backing as its structure,sintered porous bronze as its interlayer,surface inlaid the modified POM.Suitable for marginally lubricated and dry operation onthe conditions of lubrication in dents grease.It has been widely applied to metallurgical machinery, Mine machinery,water conservancy machinery,vapor lovomotive,building machinery,agriculture machinery,steel rolling industry etc.
1. Good load capacity and anti-wear.
2. It is used in high load capacities and low speed with rotational, oscillating or frequent stop-start motion.
3. It can work long time without oil in the condition of boundary lubrication, under oil or grease lubrication interval, the work is longer.
4. It is machinable for the thicker of POM.
5. The bushes can be applied in auto chassis, forging machine, metallurgical, civil engineering, power station, strip rolling industries etc.
