Zeberoxyz 2PCS Set GT2 Synchronous Wheel 20&60 Teeth 8mm Bore Aluminum Timing Pulleys with 2PCS Length 200mm Width 6mm Belt (20-60T-8B-6)

Well made pulley set. It makes it easy for me to come up with something when I'm hacking around. They even send an allen wrench for the set screws so you don't have to go fishing for one. The belt is quality made too. Very pleased with this set.

Great item! Fast shipping

Works perfectly.

Pay attention to the bore size. I ordered these thinking the smaller pulley will fit on a standard nema stepper motor shaft. The bore on the small pulley is too large but that’s my fault for not paying closer attention.

Fit perfect for the project we were making

I bought the 20-60T-10B version because I expected this to fit inside a 20mm ID bearing. As you can see from the image, the dimensions showed a 42mm outer diameter (44mm actual), 20mm flange (25mm actual), and a 10mm bore. As you can see from my measurements, the only correct thing was the 10mm bore. What is confusing is that these dimensions don't even match any other version sold under this listing, so I was not just accidentally sent another part. Something is fundamentally wrong with the listings. If you don't need specific dimensions, they work great! Otherwise, it's anyone's guess what you will receive.

Not used them yet but they fit the shaft well, look good, time will tell how they hold up.
