Verification boundary

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.
