Press Fit Force Calculator
Calculate the required force for press fitting operations with precision
Frequently Asked Questions
A press fit force is the amount of force required to assemble two parts by pressing them together where the shaft is slightly larger than the hole. This creates an interference fit that holds the parts together without additional fasteners.
The friction coefficient depends on the materials in contact. Common values are: Steel on Steel (0.10-0.20), Steel on Brass (0.15-0.25), Steel on Aluminum (0.30-0.40). You can select common material combinations in our calculator or enter a custom value.
Interference is the difference between the shaft diameter and the hole diameter before assembly. Positive interference means the shaft is larger than the hole, creating the press fit. Our calculator automatically calculates this from your input values.
This calculator provides theoretical values based on engineering formulas. Actual results may vary due to surface finish, lubrication, temperature, and other factors. Always consult with an engineer for critical applications.
