Bearing L10 Life Calculator

Calculate bearing L10 fatigue life based on ISO 281:2007. Input basic load ratings, speeds, and application factors — get estimated service hours instantly.

Basic dynamic load rating from bearing catalog
Actual load applied to bearing
Rotational speed of the bearing shaft

Formula: L10 = (C/P)p × 106 / (60 × n)

Parameters: C = Basic dynamic load rating (kN) | P = Equivalent dynamic load (kN) | n = Speed (RPM)

Exponent: p = 3 for ball bearings | p = 10/3 (≈3.33) for roller bearings

Standard: ISO 281:2007
