Bending shaft for surgical instrument

By arranging three rolling elements which compensated each other introduction of external forces into work piece during machining could be prevented.

In operation, this component is subjected to very frequent bending in a corrosive substance so that stress crack corrosion was causing defects. In this case too, the required number of cycles could be achieved after deep rolling.
