Bearing Life Calculator (L10)
Bearing Life Calculator (L10): a planned Super Calculator tool. Covers dynamic load rating c. Stub page while the tool and its worked example are prepared.
Bearing Life Calculator (L10) is a planned calculator in the engineering section of Super Calculator, covering mechanical engineering.
What this calculator will compute
Inputs: dynamic load rating C, radial and axial loads, speed (rpm), bearing type, reliability target (%), lubrication and contamination condition and temperature.
Outputs: L10 life in revolutions and hours, modified rating life, equivalent dynamic load, required C for a target life and reliability adjustment factor.
Formula, recorded as scope and not yet verified against a primary source: ISO 281 basic rating life L10 = (C/P)^p million revolutions, with p = 3 for ball bearings and 10/3 for roller bearings. Equivalent dynamic load P = X Fr + Y Fa combines radial and axial components. The modified rating life applies factors for reliability, material and lubrication.
