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) 

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)
