Specifications about ultimaker's shafts

Recommended Posts

Hello guys. I want to modify my UMO's head and I need two longer head's shafts but I don't want to lose quality. I wanted to use UM2's shaft because I think they are longer enough (they should be 320mm isn't it?) But it looks pretty difficult to me to find them and so I want to have a look somewhere else.

But I need to know the spec that I need to look for: type of the metal; bend tolerance; surface treatment etc.

Some one of you know that?

Also... Do you know if chromed bars are better? They look shiny with no rough surface and they don't get rust (which can happen with standard ultimaker''s barrs).

Thanks to all.

Misumi only sells to bushines and Igus sells to anyone. Used both kinds and both brands works for me with very nice quality.
