ENGINEERING OVERVIEW

Candidate decision overview

Data version 2

GEOMETRY CONTRACT

Conical profile

Bearing surfaces: No
Tolerance grade: See dossier / confirm

Special surface parameters must be reviewed against the released drawing; the profile name alone is not a complete geometry definition.

EVIDENCE COVERAGE

✓Manufacturer curve / stress12✓Polysplendid calculations2✓Resolved standards3✓Inspection dossier1—Approved product FEMNot public

A missing FEM record is not evidence of failed validation. It means no approved product-level study is public on this page.

COMBINATION BOUNDARY

Check single disc before stack

Parallel stacks primarily multiply load; series stacks primarily multiply travel. Friction, contact, guidance, preload and manufacturing scatter must be checked separately.
