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 (pollici).
2. Enter the Nominal Bushing Outer Diameter (ti invieremo l'ordine richiesto):
   • 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 (per esempio., 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.
