PEEK / PI High Temperature Application Plastic Bearings


TOP-16 plastic bearing.pdf

TOP-04 diameter list.pdf

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 time, The Density of PEEK plastic bearings is 1.32 g/cm3, Sliding friction coefficient is 0.30, Short-time highest application temperature is 300℃.
Moreover PEEK / PI High Temperature Application Plastic Bearings have excellent anti-corrosion performance, could be used in strong acid and alkali environment. So generally PEEK / PI High Temperature Application Plastic Bearings are used to manufacture bearings 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.
