I was planning on buying pulleys from [belting online] (http://www.beltingonline.com/18-tooth-htd5-pulley-18-5m-15f-7775), and they offer multiples options but I don’t know wich one to take ?
for example 18T 15mm wide
I choose a 8mm bore because of my motor and then what ?
Should I consider a keyway ? Will they just pierce the pulley or actually give a pulley ?
Should I consider grubscrews and if yes what size and how many ?
What’s the best : keyway or grubscrew ?
Do you have some other EU pulley sellers ?
