I'm trying to finalise the ball screw design and noticed that the standard dimensions from BST don't seem to be compatible with the FK15A bearings - looks like the spacers eaither side of the bearing are too long and there's not enough length to get the locknut on the end:

Am I missing something? Do I have to turn down the spacers? I'm planning on tweaking the end to have 2 locknuts rather than using the grubscrew, just want to make sure I'm doing it correctly.

Cheers,
