Calculation Results

Calculation Formula

Pressure (P) = (D_h - D_s) / (2 * μ * D_s)

Where:
P = Pressure (N/mm²)
D_h = Hole Diameter (mm)
D_s = Shaft Diameter (mm)
μ = Coefficient of Friction

Result

Pressure: N/A N/mm²

Press Fit Pressure Calculator Calculator Usage Guide

Learn how to use the Press Fit Pressure Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the shaft diameter in millimeters (mm).
  2. Enter the hole diameter in millimeters (mm).
  3. Enter the coefficient of friction (a dimensionless value).
  4. Click the "Calculate" button to compute the press fit pressure.
  5. The result will be displayed in Newtons per square millimeter (N/mm²).

Working Principle

The press fit pressure is calculated based on the difference between the hole and shaft diameters, divided by the product of twice the coefficient of friction and the shaft diameter. This formula helps in determining the pressure exerted during the press fit operation, which is crucial for ensuring proper alignment and fit between the shaft and the hole.
