Alfawise U20 και U30 Αξεσουάρ Τροχαλιών Αξεσουάρ τροχαλιών

Work as intended. The quality of the bearing is satisfactory. There is no loud noises coming from the wheel in operation. The machining of the metal is good enough. The rubber is uniformly black without signs of discoloration. It is also firm enough and elastic enough. The wheel fits well on the aluminium extruder strut I placed it on.

Overall satisfied with the product. Because some of my wheels weren't rolling smooth and these were a perfect replacement. The reason I'm only giving these 4 stars is because a couple of them didn't roll smooth enough for me to use on a high precision 3D printer.

My old wheels were worn down and causing the bed to stick and prints to have all sorts of problems. These replacement alfawise idler whee were the perfect match. They have smooth bearings and the feels stronger. So far I'm very happy with them.

Good quality sealed ball bearings, high density rubber and metal wheels are wearing better than expected on the extruded aluminum rails.

These wheels have 2 bearings each and roll smoothly. These wheels are a great deal and I will be ordering more for my 3d printers.
