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

Not everyone buys these for printers or whatever they advertised it for. It said it could be used with DC motors. Didnt say the belt size but it was no bigger then 200mm. Way to small. And they didnt have any option for a bigger belt unless u buy it seprete. Belt was way to short for the power I needed to make. But other then that the gears or solid and work good. Even with other belts I had to use. Amazon does not have a lot of options for belts. Other then these types. Im using a carpet cleaner belt right now. Even rubber bands put out more power. Good ones not cheap ones.

Its not what I was looking for, but seemed to be of decent quality. The ad for it could definitely be better written to fully understand the dimensions.

Works nicely, quiet and accurate

The Size and flexibility of These units make them usable for all kinds of applications other than 3D printing. They can be doubled up for higher torque for a positive drive, and not get out of sync. It would be nice if they could individually handle more force.

No son muy fuertes pero son baratos

Bought these to make a diy laser roller tool and they worked great, I only needed one set but the other set came in helpful when I needed to use them to lock the rods in between to not move up or down.

Hello, I ordered these pulleys with size: 20-40T-5B-6, the description on Amazon claims that the outer diameter of the shaft is 18mm but they came in with a much smaller diameter. Can I get pulleys with 18mm shaft please as it is crucial for my project. I know you guys used to sale pulleys with 18mm shafts because I have ordered from you before and I also noticed a small rim that measures 18mm before continuing to be bored down more. Thanks you.

il y a 4 roues dentés, chacun a 2 trous. cependant il ny que 7 boulons dentés noirs.... probablement celui qui a vérifié lemballage na pas fait attention

Habe mich über den schnellen Versand Super gefreut mein erster Antrieb in diese Richtung bei näherer Betrachtung musste ich Feststellen das der Äußere Ring von der größeren Riemenscheibe defekt ist er ist Abgebrochen und sogar durch gebrochen zudem fehlt bei der Heilen Scheibe noch die Madenschraube.

Had to get a set with a different bore but these are working nicely.
