So I’m getting a pulley made for me, but I need to get a things down before I confirm details. I plan on getting a 14T pulley suited for 15mm belts and 5mm pitch (HTD 5M). It’s going to be fitted onto my Enertion motor. I looked on Enertions website and saw the 9mm and 12mm pulley. With the 9mm pulley, it had a little part for grub screws. But the 12mm doesn’t it’s just mostly teeth from side to side. My question is, for larger belt sizes will I need grub screws like for the 9mm or can I just have it like the 12mm pulley with the keyway part, or is the belt size totally irrelevant? I could have both I think, but I thought I should ask you guys before I buy anything.
Forgive me if this is a totally stupid question.
