Dimensions, standards and downloadable engineering files are generated from published product data.
Open full drawing previewSpecial surface parameters must be reviewed against the released drawing; the profile name alone is not a complete geometry definition.
A missing FEM record is not evidence of failed validation. It means no approved product-level study is public on this page.
Parallel stacks primarily multiply load; series stacks primarily multiply travel. Friction, contact, guidance, preload and manufacturing scatter must be checked separately.
Each material and supplied-surface identity has its own database-driven workbook and PNG preview. A review or blocked status is not a production release.

Download Excel · 20.9 kBLoads, stresses, thousand-piece weights and curves retain their manufacturer, source version, page/worksheet, material and temperature condition. A catalog value is an engineering reference unless the inspection dossier separately identifies an approved acceptance tolerance.
This source table publishes a summary (weight and/or σOM) but no displacement-load points; no curve has been invented.

| Hardness— | material_condition_requiredFinished hardness for material 1.4923 shall be tied to its cold-work, ageing, or quench-and-temper condition and to a vendor/order source. The ordinary 50CrV4/51CrV4 range of 42–52 HRC is not reused. Structured vendor-condition values are stored as contextual inspection requirements. | material_condition_required | DIN EN 16983:2017-09— |
Where cone-height limits are shown, they are derived references only. Flatness and parallelism become acceptance criteria only after an approved drawing, process card or supply agreement supplies numeric values.
