Press Fit Retention
Screen press-fit torque and axial retention from user-entered interface pressure, diameter, engagement length, and friction.

WHAT THIS SCREEN ANSWERS
A press fit uses contact pressure and friction to retain axial load or torque. The screen starts from user-entered interface pressure rather than claiming an interference result from incomplete geometry. Keep the stated condition attached to the number when it is shared.
Surface finish, lubrication, yielding, wall thickness, thermal cycling, and assembly condition can change retention. Confirm interference, materials, hubs, surface condition, assembly force, temperature range, and failure consequences. That is the boundary of this preliminary screen.
A press fit uses contact pressure and friction to retain axial load or torque. Surface finish, lubrication, yielding, wall thickness, thermal cycling, and assembly condition can change retention. The displayed relation is intentionally simpler than a release calculation.
The screen starts from user-entered interface pressure rather than claiming an interference result from incomplete geometry. Confirm interference, materials, hubs, surface condition, assembly force, temperature range, and failure consequences. The decision remains specific to this application because a press fit uses contact pressure and friction to retain axial load or torque. Turn the remaining unknowns into a short verification list.
