I needed some of these for a CNC project I am working on and these were perfect. They spin well and fit the belt just as intended. The surface is smooth unlike what the pictures seems to show.

Although I wish the Bearings were changeable. Biggest problem with these type of things is there’s no way to change the bearings. You have to replace the whole unit. And my case on my 3-D printer after a year they’re gone.

La spalla sull'anello interno è di mezzo millimetro rendendo difficile l'assemblaggio ma il prodotto funziona bene

I am building a Lowrider V3 CNC from V1 Engineering and these form part of that build. I have done the 3D printing part of the build and gathering all of the necessary parts.Whilst I haven't put everything together yet, after my initial research and inspection of these, I am very happy. I will update the review once I have completed the build.
