Bearing Engineering Tool
Bearing Interference Fit Clearance Calculator
Estimate bearing internal clearance reduction caused by interference fit between the bearing outer ring and housing bore.
Clearance Reduction--mm
About This Calculator
This tool helps estimate clearance reduction caused by radial interference between the bearing outside diameter and housing bore.
How to Use the Calculator
Enter radial interference, bearing outside diameter, outer raceway diameter, housing bore diameter, Poisson ratios, and elastic modulus values for the bearing and housing material.
Important Note
Use this result as a preliminary engineering reference. Final fit selection should consider temperature, housing material, wall thickness, load direction, bearing clearance class, and assembly process.
