Why is bearing PEEK material so expensive?

Bearing PEEK material is a special engineering plastic, well known as the “King of Plastics”. It is based on high-performance engineering plastic PEEK and has excellent heat resistance, chemical stability, dimensional stability and mechanical properties, and can adapt to various harsh working environments. It is widely used in bearings with high temperature, low viscosity lubricants and corrosive environments, such as tilting pad thrust bearings and journal bearings.

As for why PEEK materials are more expensive, on the one hand, it is because PEEK materials are high-performance materials that require special production processes and raw materials, and the production costs are high. At the same time, due to the wide range of characteristics and application fields of PEEK materials, the demand is large and the market supply is tight, so the price is naturally relatively high.On the other hand, PEEK materials have excellent properties such as high temperature resistance, corrosion resistance, wear resistance and self-lubricating properties, which can effectively reduce friction and improve efficiency, reduce the risk of failure and extend the service life of components, thus bringing better results to users. Great value. In the current market, the price of PEEK material is about 500 yuan/kg. Although there are some shortcomings, such as difficulty in processing and poor melt fluidity, its comprehensive performance and economic benefits make it popular in all walks of life. widely used.

In the aerospace field, PEEK materials are widely used in the manufacture of parts such as rocket nozzles and fuel injectors. These parts play a vital role in rocket propulsion and fuel control, and PEEK material has the advantages of high temperature resistance and corrosion resistance, so it can maintain excellent performance in this high temperature and high pressure environment.

In the medical field, PEEK materials are used to manufacture medical devices such as fracture fixators, heart stents, and prostheses. Due to its high strength, low wear and corrosion resistance, PEEK material can greatly improve the service life and safety of these medical devices.

In the field of automobile manufacturing, PEEK materials are widely used to manufacture engine parts, transmission shafts, lamp covers and other parts. These parts are critical to the performance and safety of automobiles, and PEEK material’s high strength, wear resistance and low weight properties can meet the needs of the automotive industry.

In the field of petrochemical industry, PEEK materials are widely used in manufacturing components of petrochemical equipment, such as mixers, heat exchangers, pipes, etc. These parts need to withstand environmental conditions such as high temperature, high pressure and corrosion, and the corrosion resistance, high temperature resistance and high strength of PEEK material make it an ideal choice.

To sum up, PEEK materials are widely used in aerospace, medical, automobile manufacturing, petrochemical and other fields. These cases prove the high performance and superiority of PEEK materials, and also reflect its broad application prospects.
