Bearing Fit Calculator
ISO 286 shaft and housing tolerance analysis — calculate clearance, transition, or interference fit for bearing mounting.
Inputs
ISO Recommendation Quick Ref
Shaft (inner ring)
Rotating load: k5/k6 (light→normal) | m6 (heavy)
Stationary load: h6/js6
Housing (outer ring)
Stationary: H7 (most cases)
Rotating outer: M7/N7
Fit Analysis
Max clearance / min interference
Min clearance / max interference
Enter shaft and housing dimensions, then click Analyze Fit.
Note: Values from ISO 286-1:2010. This covers only the geometric tolerance fit. Thermal expansion, mounting method (press/shrink), and bearing internal clearance class must be considered separately.
