Press Fit Pressure Calculator

Formula

To calculate the press fit pressure:

\[ Pfit = \frac{Fp}{CA} \]

Where:

\(Pfit\) is the Press Fit Pressure (psi)
\(Fp\) is the Press Fit Force (lbf)
\(CA\) is the Total Contact Area (in²)

What is Press Fit Pressure?

Press fit pressure is the pressure exerted when two parts are pressed together. It is calculated by dividing the press fit force by the total contact area. This measurement is important in engineering and manufacturing to ensure that parts fit together with the correct amount of force, ensuring proper functionality and durability.

Example Calculation 1

Let's assume the following values:

Press Fit Force (\(Fp\)) = 500 lbf
Total Contact Area (\(CA\)) = 2 in²

Using the formula:

\[ Pfit = \frac{500}{2} = 250 \, \text{psi} \]

The Press Fit Pressure is 250 psi.

Example Calculation 2

Let's assume the following values:

Press Fit Force (\(Fp\)) = 1000 lbf
Total Contact Area (\(CA\)) = 4 in²

Using the formula:

\[ Pfit = \frac{1000}{4} = 250 \, \text{psi} \]

The Press Fit Pressure is 250 psi.
