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)

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.

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.

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!

Works nicely, quiet and accurate

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.

The pulley and belt are good quality.

The picture made me think the gears were bigger than they are. They still worked for my project

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.

Alles OK.

Very good quality parts but were a bit small for what I needed.
