Would pulleys that might be 10mm work?

On AliExpress I purchased a number of items from POWGE.

They were listed in one place as 9mm and in another as 10mm.

GT2 or 2GT?

GT2, 2mm pitch (Technically the link below is is GT3, GT2/GT3 does not indicate pitch, rather it indicates series. GT2/GT3 pulleys are identical) - starts at 24mm for 6.35mm shaft

Here is a link to where I ordered my 20 tooth pulleys. They have a wide selection of such items.

i bought from mellow store , thanks guys .

i have another question - i own kollmorgen powermax 2 motors , model m22nrxb . unfortunately they come with imperial shaft with key . the shaft is 3/8" diameter . any chance to find a suitable pulley for this shaft and a 9mm 2gt gates belt?
i can get away using couplings , not sure if its worth it over regular stepperonline nema23 motors .

https://www.electromate.com/m22nrxb-l/

this says the shaft is 0.25 inch.

[hackinistrator]

@Veti there is custom config available for those motors , i have dual shaft 3/8"
see here http://www.portalnaukowy.edu.pl/allegro/powermax22.pdf

i think your best bet is to ask the stepper motor manufacturer if they make them.
