Verification boundary
What still needs to match
Exact set architectureConfirm metric versus inch family, cone/cup identity, series, and complete designation.
Fits and geometryVerify shaft/housing seats, shoulders, fillets, preload/endplay, and mounting arrangement.
DutyCheck combined radial/axial loading, lubrication, speed, temperature, contamination, and required life.
