Plastic Bearings >> PEEK/PI (High temperature application) plastic bearings
As newly developing engineering plastic material, PEEK and PI have been approved have the strongest mechanical strength and could endure the highest temperature among all the plastic material. PEEK could work at 260℃ and PI at 300℃ in long-term. Moreover they have excellent.anti-corrosion performance could be used in strong acid and alkali environment. So generally they are used to manufacture bearings 5 to realize precision running in rigor environment. As the material is expensive, the costs are high. Generally the rings made with PEEK or PI. Cage with PTFE, PEEK or PI and ball with ZrO2 or Si3N4.
