ballnut housing and floating end ballscrew assembly

[John S]

Gents,

excuse the rather massive thread attack, but I'd rather ask than be sorry later.

Any reasons why ballnuts are normally mounted inside a housing rather than bolted on top? See attached drawing.




Regards,

Unless I'm missing something very obvious the two drawing will take up exactly the same space.
It's the flange that controls how much room you have.
