Bearings used in medical device application must meet unique requirements because of the extraordinary condition in which they perform. Biocompatibility, corrosion resistance and sterilization are just a few of the challenges medical bearings must accommodate. With over 15 years of experience, ZYZ bearings are worth your trust. ZYZ medical bearings are manufactured from 440C stainless steel. The material’s corrosion resistance allows for repeated sterilizing. ZYZ highly finished, honed surface provides a long lasting structure for the 440C or Silicon Nitride (ceramic) balls, which allows the bearing to rotate smoothly at the high speed.
