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)

No son muy fuertes pero son baratos

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

Alles OK.

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.

Great for a precision 2 to 1 ratio.

In der Artikelbeschreibung steht, dass der Riemen 200mm lang sei. Bei einem Rieben ist die Länge für mich nicht der Umfang! Hier beträgt der Umfang 200mm! Achtung! Den Artikel bewerte ich an dieser Stelle nicht, da er umgehend zurück gegangen ist.

The pulley and belt are good quality.

Vraiment très bon de mon attente

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.

Works nicely, quiet and accurate
