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 · 21.3 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.

| Outside diameterD / De | 200 mm (-0.46/+0 mm); limits 199.54–200 mmThe high-temperature product keeps its material and vendor identity. Dimensional tolerances, coaxiality and guide clearances use the DIN EN 16983 general range rules; hardness is resolved separately from the material condition and vendor/order source. | Resolved | DIN EN 16983:2017-09EN 16983 page 12（PDF 14） |

| Cone heighth0 / h₀ | 4.3 mmFor this supplementary geometry, h0 follows the catalog nominal base thickness t. The finished t-prime tolerance is not reused to invent an independent h0 acceptance limit. | nominal_reference_only | DIN-EN-16983-2017-09Supplementary catalog geometry with DIN EN 16983 general tolerance basis |
| Coaxiality— | ≤ 0.92 mmThe high-temperature product keeps its material and vendor identity.

| Flatness— | Set by approved drawing, process card or supply agreementThe standard does not provide a universal independent numeric tolerance; an approved drawing, process card or supply agreement must provide the acceptance value. | Agreement required | POLYSPLENDID-INSPECTION-POLICY-2026-08Task 121 标准原文核对结论 |

| Test loadFt | Percentage tolerance onlyThe percentage tolerance is resolved, but an approved nominal test load is missing; no absolute N limits are generated. | Percentage tolerance only | DIN EN 16983:2017-09EN 16983 pages 13～14（PDF 15～16） |
| 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.
