WINSINN GT2 Pulley 20 Teeth 5mm bore 6mm Width 20T Timing Belt Pulley Wheel Aluminum for 3D Printer (Pack of 5Pcs)

These worked out great and seem to be quality made. The only issue I had is that one of the socket screws was inserted the wrong way so the allen key wouldnt work. I had to take time to unscrew it using pressure while turning but it eventually came out. Once I flipped the screw over I could use the allen key and all was well. Im guessing they use a machine or magnetic tool to insert the screws because there is no way an allen key could put in backwards like it was.

This product was very good and didnt scratch easily like my other pulleys that scratched when I pulled the flanges off. Overall this product did its job very well, no complaints here.

I used these to modify my CR-10s 3D printer to synchronize the z-axis lead screws. I attached them at the top of the machine and connected them with a belt and tensioner (3D printed). Works great! I used a 760-2GT-6 belt to connect the pulleys.

Work perfectly. Only missing one screw, but only needed three of the five pulleys, so tool one from unused.

Used to install a stepper in a modification of a machine

I needed a set of these for doing Z-Axis sync on a CR-10 V2. These fit perfectly and seem to be well made. I like the double set screws on each for added security. The price is right for good enough quality. Nothing more you can ask for.

Arrived quickly, they work fine, seem to be good quality. I think they will work fine for my 3d printer application.

I used these for a timing belt on my ender 3 v2 and works perfect with no complaints.

Perfect size for my dual z stepper sync. Good quality materials.
