Thanks guys for the tips BTW the construction is based on aluminum profiles (20X40) if it matters I considered shoulder bolts indeed, but eventually I bumped into this: which will sit perfectly on the profile. I'll put 5mm shaft between 2 bearings and lock the pulley with its M4 on the shaft How important is it that the pulley won't move to the sides? (let's say 1mm max) As I see it - 1mm toby Shachar85 - General
Or just fix the 5mm shaft and slip the pulley on it? sorry, I don't understand why the coupling is for?by Shachar85 - General
Hi I'm new around, so I hope no problems with the question. Searched the net pretty deep with no good answer. I started designing a printer. I got stuck in the pulley assembly stage. The side that attached to the motor is obvious of course. What about the other side? Do I have to assemble it on 5mm smooth rod, or will 5mm bolt do the job? Thanksby Shachar85 - General
