  • Undercut between bearing seating and shaft shoulder ...

    2004-1-9  I assume you are grinding the shaft, since you mention a bearing, and a pretty small one at that, so to achieve the necessary tolerances it would probably be essential to grind. If you want an accurate shoulder, the undercut should ideally be an angled type so that you have wheel clearance on both the shaft and shoulder surfaces.
