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)

It’s nice and solid construction it’s not going to break or warp anytime soon

The pulley and belt are good quality.

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.

Das Loch für die Aufnahme der Achse ist komplett außermittig und schief durch das Zahnriemenrad gebohrt. Auf einem Stepper-Motor aufgesetzt eiert und wackelt es furchtbar. Damit ist es höchstens für Spielereien zu gebrauchen, kann aber keine präzisen Anforderungen erfüllen!

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.

The set appears nicely made, I thought I only received 3 set screws, I was wrong, the rest were screwed deep into the aluminum boss, not visible to my old eyes, lol. Synchronous belts are very efficient, great for many types of projects. Great for the price!

Excellent quality especially for the price and they even come with an Allen key for the set screws

Alles OK.

Great for a precision 2 to 1 ratio.
