48 PCS 3D Printer POM Pulley Wheel Set with Pulley Bearing Included 16 PCS Pulley Wheels 16 PCS Eccentric Spacer 16PCS Round Column for Creality Anycubic Anet Series 3D Printer Ender 3

Ordered these to fix my Atomstack laser but instead used them on my friends Sculpfun laser instead to resolve the chatter problem on the X axis. Fit perfect. Still have alot left over.

Was building a linear rail prop and these worked exceptionally well. Would order again

Good value and I have a lot of parts left over for new adventure

They are fantastic, after you wear them in. I used these as replacements on my 3D Printer and they had some residue wear off, after about 3 prints they stopped and have been rolling smooth ever since.

I customize a number of my printers and this set of pulley wheels are very good quality and a great deal. It is just what I needed for my custom builds and a few extra for replacements. The rollers are of better quality than what originally came on my Ender 3 Max. My only complaint is how long these took to arrive. All in all this is a great set and well worth the price. Full 5 stars for sure!

The description stated that the eccentrics were 6 mm high, but in fact, 8 mm eccentrics were included in the set.

The packages I received had a mixture of 6mm and 8mm eccentric spacer as well as 6mm & 8mm rounds spacers. The POM wheels were good quality

4 of the rollers had flat spots. Luckily I had more than I needed so the spares were ok

Lo usé para usarlo sobre un eje 20x20 y las ruedas coinciden perfecto.
