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. |

As near as I can see, around 263/264mm. The clip grooves are 3mm in from the ends, it fits perfectly on an M900 swingarm but although long enough to fit flush with my old 851/888 arm, it was too short to fit the clips.

From their website I think the one Red Fox has may be the same as yours DD but they list if for a 750 or 900ss. Are you around tomorrow evening at all? I'm off to Wales Saturday for a week otherwise Cheers - Ben

Sorry no pics at mo, but axle from Tim was finally wide enough and safely bolts in full width.
Now have brand new NOS 900 and 600 axles to sell when project completed
