The swinging arm spindle runs in needle rollers so the material chosen needs to be hard enough to withstand the rollers running on the shaft. The original shafts were hardened and ground (probably made from 52100) steel which has a Rockwell hardness of 62 - 66 HRC.
Stainless steel typically has a hardness range between 20 and 60 on the Rockwell scales. The specific hardness will depend on factors such as the alloying elements present, heat treatment, and the desired balance of properties for the intended application. Even the better titanium alloys, the highest strength ones, will only get to mid 40's on the Rockwell C hardness scale. |
