Bushing Size Calculator

How to Use the “Press Fit Bushing – Hole Size Calculator”

1. Select Units:
   • Choose the measurement unit from the “Units” dropdown:
     • Metric (mm): For metric measurements (millimeters).
     • Inch: For imperial measurements (inches).
2. Enter the Nominal Bushing Outer Diameter (OD):
   • In the “Nominal Bushing OD” input field, enter the outer diameter of the bushing.
   • Make sure to use the same units you selected in the previous step (e.g., if you selected “Metric,” enter the OD in millimeters).
3. Click the “Calculate Hole Size” Button:
   • Press the “Calculate Hole Size” button to perform the calculations.
4. View the Results:
   • The calculator will display the calculated values in a results section below the button. The results will include:
     • Actual Bushing OD – MIN and MAX (s6): These are the minimum and maximum calculated values for the actual bushing outer diameter, based on the s6 fit class tolerances.
     • Installation Hole – MIN and MAX (H7): These are the recommended minimum and maximum installation hole sizes for the H7 fit class.

These results indicate the range of dimensions to ensure a proper press fit for the bushing.

When to Use the Calculator:

• Use this tool when you need to determine the appropriate installation hole size for standard press fit bushings.
• Ideal for mechanical engineers, machinists, or hobbyists working with press fits in metalworking, reloading, or similar applications.
