5PCs Aluminum 2GT Timing Pulley 20 Teeth Bore 8mm for 3D Printer 10mm Width 2GT Timing Belt

Overall, the pulleys are of good quality. The teeth are well cut and fit my belts perfectly, grub screw holes are nicely threaded and the bore size is accurate with a nice fit on my 8mm rods. Pulleys arrived in fairly good condition despite the packaging being a little lacking. I'm quite happy with the pulleys on the whole and would recommend them as the overall quality is quite good. Exceptional at this price point.

There are no obvious flaws in manufacturing, and they fit my printer perfectly without any issues.

Cheap and good quality.

Fit perfect for my Christmas village conveyor

The finish on the outside of the gears was very good, but the teeth were damaged in several places. Normally, I wouldn't consider this to be a major concern. However, the use case that I had in mind was for these gears to be used in a high torque application so these imperfections will likely damage the expensive timing belts.I do not intend to return these gears since I already removed the flanges, but I will purchase gears/pulleys from a different supplier in the future. One way that this problem could be avoided in the future is if the gears were wrapped in foam tape around their teeth before shipping. I suspect that the damage to the teeth is due to the gears moving around during transit.

The teeth are obviously damaged and easy to see since they are packaged in clear zip lock. Why send it to a customer only to have them returned. Hassle for everyone and a waste of time. ReliaBot, do better! Check your parts before shipping.
