The 80mm outside diameter was spot-on for my lathe's bearing housing, and the metal feels sturdy enough to last. Installed it in a few minutes with no alignment issues, which is exactly what I needed.

Fits perfectly on my SIEG SC2 mini lathe, the 80mm outer diameter is exactly what I needed. The aluminum casting has a nice, clean finish with no sharp edges. Installed in minutes and the bearings are well-protected now.

Replacing the old bearing cover was a straightforward job — the 80mm OD lined up flush with the housing, and the lack of a notch for the intermediate shaft is exactly what my SC2 needed. It’s a simple, solid piece that does its job without fuss.
