Ketron™ SP HPV PEEK bearing grade is reinforced with carbon fiber, graphite and PTFE lubricants. With the lowest coefficient of friction and the best machinability for all PEEK grades, it is an excellent combination of low friction, low wear, high LPV, low mating part wear and easy machining. This makes it ideal for aggressive service bearings, bushings, rollers and thrust washers.
