Out of interest what are the flats for? Are you fixing the ball screw and turning the nut?
Also 0.25mm is going to be very sloppy on the bearing and may cause you problems?Visit Us: www.automationshop.co.uk

Did I say zero backlash? I suppose 20 microns would be close enough
How soon can I have them?
The shorter screw is the mill Y axis, can't end support it without cutting lots of iron out the way.

On monday i will draw it up and send the drawing to the engineering company to get a price.
It looks quite easy so i guess the price will be quite similar.
Email me your details and i will respond over email with the rest.
Delivery time will be about 2 weeks i think.

The flats are for the grub screws that lock the pulleys and handles in place. The nuts hold tension against belleville washers I wouldn't want to rely on them to grip anything.
The tolerance does not apply to the shaft diameter, that wants to be a nice sliding fit. I'm sure you can do better than .25mm anyway.
