Retainer, Bearing Rear Shaft CLEARANCE

The bearing sits snug on the rear shaft and hasn’t budged through a few hours of milling. Machining the X3 is noticeably quieter now that everything’s locked in place.

Perfect fit on the X3 mill's rear shaft and the machined clearance holes lined up exactly with the existing bearing cover, so installation took me under five minutes. It's holding the bearing snug with zero play during a full afternoon of runs.

Was a little worried about getting the right fit for my X3, but this retainer slipped onto the rear shaft perfectly and locks the bearing down solid. Machining is clean with no sharp edges, and it feels like it’ll hold up for years of use.
