Verification boundary

What still needs to match

Do not infer interchange
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.
Current manufacturer dataUse the linked JTEKT/Koyo calculation and CAD tools before ordering.
