ENGINEERING OVERVIEW

Data version 3GEOMETRY CONTRACTSpherical profile

- 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 / stressNot public—Polysplendid calculationsNot public—Resolved standardsNot public—Inspection dossierNot public—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 BOUNDARYCheck 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.
