The fit on my small mill's lower pulley position was exactly right, and the timing belt tracks true now without any wobble during a full run. For the price, this flange solved my alignment issue on the first try.

The flange sits snug against the pulley bore and the belt tracks dead straight during a full hour of milling, no drift at all. Machining looks clean and the bolt holes mate up without any filing. Exactly what the lower mount needed.

The fit on my small mill's pulley was spot-on, and the flange keeps the timing belt perfectly aligned with zero slipping. It’s a simple part, but it solved my belt tracking issue in a few minutes.
