    For the RF-45 go ahead and run the 25mm. It will last longer.

    Dear dazp1976,
    Thank you for your advice.
    As regards using the 1605DFU ballscrews.
    Not heard of that classification, but will look it up.
    I was thinking of using Two RK12 End support pre-loaded angular contact bearings on each end of the X Axis.
    As one end is motor driven other has a the handwheel.
    Thanks again, Best wishes.

    When you've found the needed lengths, find linearmotionbearings2008 on eBay. I can't remember his direct email address. He is the one most recommend for ballscrews. He can machine the screws to your drawings as well. He has both single and double nuts.
