PEEK,PI High temperature resistant plastic bearingsDetailed product description：

PEEK and PI, as emerging engineering plastic materials, have been proven to have the best mechanical strength, dimensional stability, and high temperature resistance among all known engineering plastics. PEEK has a long-term use temperature of 260 ℃, while PI has a long-term use temperature of up to 300 ℃, and it has excellent corrosion resistance. Only concentrated sulfuric acid can dissolve and destroy it, and it can still operate freely in medium strength acidic and alkaline corrosion environments. Therefore, it is generally used to make bearings that require precise operation in harsh environments. Its disadvantage is that the material itself is relatively expensive, so the cost of use is high. Generally, PEEK or PI is selected as the inner and outer ring materials, PTFE, PEEK or PI as the cage material, and ZrO2 or Si3N4 ceramic balls are used as the ball bearings.

PEEK, PI high-temperature resistant plastic bearing characteristics:

1. High temperature resistance, with a high glass transition temperature and melting point (334 ℃), and a load thermal deformation temperature of up to 316 ℃. The continuous use temperature is 260 ℃;
2. Outstanding sliding characteristics, suitable for applications with strict requirements for low friction coefficient and wear resistance;
3. Water resistance, which can maintain excellent characteristics even after continuous use in high temperature and high pressure water;
4. Intensity resistance; 5. Fatigue resistance; 6. Corrosion resistance

Main uses:
Mechanical and electrical equipment, fitness equipment, food machinery, furniture, and decorative building materials
