Hi Chaps,
I want a nonstandard 2005 ballscrew length (266mm) and it occurs to me that I could simply cut it to length with an angle grinder :) (with 1 or 2 precautions)
To overcome the problem of re-machining the floating end to accept a BF15 bearing block can I use a BF20 bearing block with the ballscrew threads in direct contact with the bearing inner sleeve? As it looks as if the BK20 bearing is 10mm thick there would always be two threads in contact with the bearing. Of course I would not be able to use a retaining circlip but they are superfluous anyhow as the BK holds the shaft in position and the application is axial (compressive) load only.
Seems too simple am I missing something?
Any comments on the need for a BF block in the first place for such a short length and axial load would be appreciated.
Cheers
David
