Description


PI Resistant To Elevated Temperatures Plastic Bearings

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