Quality seems solid, definitely good value for money. Time will tell if they last, but so far so good. A few words about alignment: people complain that bearings aren't aligned. The factory doesn't seem to understand that pillow block bearings must have angular compliance to accommodate misalignment when installed. You criticize a key feature of this type of storage. Also they are not pressed in, if you tilt the bearing 90 degrees in the housing then it can be pushed out for replacement. All you need to align these bearings is to install both and then insert the shaft from one end. When it's off, just pull it towards the center and the bearing will rotate. Repeat for the other side and the shaft should go through with no problems.
