Polyether ether ketones (PEEK) are engineering thermoplastics with high tensile strength, stiffness, high heat distortion temperature and good sliding and friction behaviour.
PEEK offers chemical and water resistance similar to PPS (Polyphenylene Sulfide), but can operate at higher temperatures. PEEK bearings can be used continuously to 480°F (250°C) and in hot water or steam without permanent loss in physical properties.
High temperature capability
Light weight - low start up torque
Can run in liquids
