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.
