Compute the force required to press an inner ring onto a shaft (or an outer ring into a housing) for a cylindrical interference fit, using the maximum interference.
| Coefficient Ca | — |
| Coefficient Ci | — |
| Max interface pressure pfmax | — N/mm² |
| Press force F | — N |
| Press force (ton) | — t |
| Final press force (3.3×) | — N |
| Final press force (ton) | — t |
Requirements: guide chamfer ≤ 15% of fit length, lubrication on the fit surface, vent hole for blind bores.
Select a press with 3–3.5× the computed force. Final force shown uses 3.3×.
