Good quality of the 20T GT2 bore timing pulley lets see how it works on the proyect, all five looks good. Thank you BG

Perfect replacements for my Prusa MK2.5s idler pulleys. These have 2 bearings instead of the single bearing the ones have from Prusa. They roll smoothly and don't tip to one side or the other as they roll. One caution, the bearings are quite small, not sure how long they will last. But that's why I got the 5 pack.

They look fine. I have not tested them, as they are for emergency spares. But I actuals ordered the wrong part, I needed a 5mm bore, and that is not prominently displayed, so I missed that part, and these are 3mm bore, so, now to see if I can swop with someone in my country.

Used in place of original Prusa timing pulleys to improve the belt path and keep it straight and even. This product is fine and I would buy it again.
