need help finding a pulley

i need to find a pulley exactly 17mm in diameter and with 19 teeth... and for 15mm belt...

ive posted a whole thread elsewhere explaining my setup but for now i need to know exactly where to buy this, what its called or referred to as, what the pitch is considered...

is this 3mm pitch??

ive looked on the internet for pulley calculators but none of them let you enter diameter and teeth amount to get other specs such as pitch etc... other than that i have minimal knowledge of pulleys (otherwise i wouldnt be looking for calculators on the internet)...

i have just bought a few of these below in the link htd 5m, 17.5mm but only 12 tooth.
so the next belt size down is 3m but you might have to go with 20t is 18mm.
the next size down is 3m 16t thats 15mm

Try to avoid opening multiple threads at the same time. Just put all your questions into one place. I like to use the sdp-si calculator to look at pulleys.

One of your specs must be wrong since 19 teeth and 17mm diameter don't really match.

hey all,
efinitely has 19 teeth lol thats the one spec i know isnt wrong

ive found this product which is 17.4mm with 19 teeth but is only for 9mm belts... just to give you guys an example of what im looking for...
