PEEK ball, PEEK universal ball and PEEK roll ball are widely used in semiconductor, food packaging, automobile manufacturing and other industries. Compared with traditional metal ball and rubber ball, PEEK has incomparable advantages, such as good wear resistance and self-lubrication, high compressive strength, low creep property, lighter than metal for quick reaction, no damage to metal base, noise reduction, good mechanical properties, good chemical corrosion resistance to protect parts and extend their service life.
