    Is this the bearings you are talking about?

    Thanks for advice

    Yes those are correct bearings. Just tell Fred the f length you require but as I have said the ball screw length includes the f length . Its an easy mistake to make.

    So just order say ball screw machined both ends 1610 x 1200 with f length of 30mm

    (where 1200 is the total length)

    For the avoidance of doubt my router has twin screws twin motors and the screws are 1450mm overall. Motors nema 23 . without any problems.
