I used these for a timing belt on my ender 3 v2 and works perfect with no complaints. These were used with a tensioner for the timing belt and haven't had an issue.

I've purchased two sets of these and have had no issues with any of the pulleys or bearings.

I purchased the 20 Teeth 4mm Bore 6mm Width set of 5 twice ( I needed 8 idlers). They have all been fine. No issues of any kind. I've come to trust Winsinn as one of my main suppliers for my DIY 3d printing mechanical parts.

about average for cheep chines bearings

Reviewed in the United States 🇺🇸 on April 26, 2020

Size: 6mm BeltStyle: 3mm Bore 16T With ToothVerified Purchase

used on a custom-built 3d printer wanted 3 mm through holes. problem with 3 mm hole is bearing are always trash due to small size. so far went through 3 of the five expected the last two to fail soon. if you can make it happen, try and upgrade to a 5mm hole will get more bearing and likely have longer survivability otherwise cheap chines is really your only option on amazon.

3d Printer fixed

Reviewed in the United States 🇺🇸 on February 19, 2021

Size: 6mm BeltStyle: 3mm Bore 16T With ToothVerified Purchase

My Anet A8 printer started making rattling noises I hadn't heard before, but couldn't quite figure out what was causing them, though clearly had to do with movement on the x axis. Not long after that, it froze up so it was easy to figure out one of the pulleys wasn't working. I ordered this to replace it and it's restored to normal function. Now I have 4 spares for backup parts.

Exactly what I needed

Reviewed in the United States 🇺🇸 on June 1, 2019

Verified PurchaseEarly Reviewer Rewards(What's this?)

I had a specific need to add a GT2 belt pulley to a location that already utilized and M4 mount screw. M3 and M5 pulleys were common an easy to come by but I had a harder time finding something that would mount on an M4. These were relatively inexpensive, were available with prime shipping, arrived on time and packaging was sufficient to protect the pulleys. Perfect solution! I’ve bought two of these packs now and have included links in the bill of materials for multiple linear motion projects. I’ll have no worries buying again from winsinn when I need more.

They seem fine

Reviewed in the United States 🇺🇸 on May 18, 2018

Size: 6mm BeltStyle: 3mm Bore 16T With ToothVerified Purchase

I bought these. They seem fine. All spin true; no wobbles, etc. No noticeable manufacturing residue. Bearings seemed clean but not pre-lubricated, so I put some oil on them. I have not installed any yet (they're spares, because I just used-up my last existing spare), so I'm hesitant to give them a 5 star. Consider this an enthusiastic 4 star (because it's hard to give a 5 star when you haven't actually used the product yet.) If you're thinking of buying them, go for it, because they seem at-least decent quality.

Buy them for the cute grindy sound they will make when they explode!

Reviewed in the United States 🇺🇸 on March 2, 2022

Size: 6mm BeltStyle: 3mm Bore 16T With ToothVerified Purchase

These are perfect for things like slowly rotating a ball of yarn while your grandma knits. But if you even think about using them for anything with more radial load or >single digit RPMs, the bearings will simply sublime into the air like like the last puff on a barely-burning cigarette. Of course you might think you'll get lucky, or that thousands of reviews from people who gave them five stars! because they were cheap and round and shiny and came with Prime shipping are worth something. But the bearings in these are both low quality and extremely small, and the combo means you really can't count on these to spin freely for very long.

Piece of garbage

Reviewed in Canada 🇨🇦 on April 23, 2022

Size: 6mm BeltStyle: 5mm Bore 20T With ToothVerified Purchase

Bearing was working fine for a week or so. After my 8 day print, I do another one after that and it starts making noise
Then after a day in my print, layer shift appeared. Opened my printer up and saw the bearing exploded. Like whats going on with the QC from this vendor

Not the right size pulley

The diameter of the pulley is actually 14mm, instead of 12mm.

From 10 units not even one had bearing which worked - every single one worked like it had sand instead ball bearings inside. Total height of pulley is 14mm not 13mm as it should be.

Miserable Fertigungsqualität

Reviewed in Germany 🇩🇪 on January 22, 2022

Size: 6mm BeltStyle: 5mm Bore 20T With ToothVerified Purchase

Diese Idler Pulleys würde ich nicht mal geschenkt nehmen. Jeder Pulley hatte einen anderen Fehler. Insgesamt liefen alle Lager sehr schwergängig. Bei einigen war die Erhöhung am Rand total schief aufgepresst. Eines habe ich optisch für gut befunden und ausprobiert, aber dieses eierte dann auf der Welle - total unbrauchbar.
Leider habe ich keine Bilder gemacht, da ich die Pulleys aus Frust direkt retourniert habe.

Meine persönliche Empfehlung: nicht kaufen - auch nicht mal ausprobieren. Zu schade um das CO2…

Zahnform passt nicht richtig!!!

Reviewed in Germany 🇩🇪 on April 18, 2022

Size: 6mm BeltStyle: 5mm Bore 20T With ToothVerified Purchase

Habe diese gt2 Zahnrollen mit 20 Zähnen für meinen Ender3 V2 bestellt. Anfangs sah alles gut aus, nur nach der Montage machte der Zahnriemen Gräusche. Bei der Ursachenforschung habe ich dann bemerkt, dass die Zahnform nicht genau oder falsch ist und der Zahnriemen nicht richtig in die Vertiefungen passt. Bei den original Riemen Rädern der Metallspanner passt der Riemen perfekt. So kann man diese Chinadinger im Müll entsorgen. Echt ärgerlich und wenn man da nicht gleich draufkommt ist der Riemen auch im A....!
