Enter the press fit force (lbf) and the total contact area (in^2) into the calculator to determine the Press Fit Pressure. 

Press Fit Pressure Formula

The following formula is used to calculate the Press Fit Pressure. 

Pfit = Fp / CA
  • Where Pfit is the Press Fit Pressure (psi)
  • Fp is the press fit force (lbf) 
  • CA is the total contact area (in^2) 

To calculate the press fit pressure, divide the press fit force by the total contact area.

How to Calculate Press Fit Pressure?

The following two example problems outline how to calculate the Press Fit Pressure.

Example Problem #1:

  1. First, determine the press fit force (lbf). In this example, the press fit force (lbf) is given as 750.
  2. Next, determine the total contact area (in^2). For this problem, the total contact area (in^2) is given as 3.
  3. Finally, calculate the Press Fit Pressure using the equation above: 

Pfit = Fp / CA

Inserting the values from above and solving the equation: 

Pfit =750 / 3 = 250 (psi)

Example Problem #2: 

Using the same process as above, first define the variables required by the formula. In this case, these values are:

press fit force (lbf) = 1000

total contact area (in^2) = 5

Entering these values yields:

Pfit = 1000 / 5 = 200 (psi)
