⚙️ Fan Vibration & Bearing Life Predictor

Calculate L10 fatigue life (Hours) and characteristic fault frequencies (Hz) for fan bearings.

1. General Fan & Load Parameters

Fan Speed (n)

RPM

Dynamic Load Rating (C)

Equivalent Dynamic Load (P)

Life Exponent (a)

Operating Temperature

°C

2. Bearing Geometry Factors (For Vibration Frequency)

Input dimensionless factors derived from bearing design. Consult bearing catalog for precise values.

Outer Race Factor (BPFO)

Inner Race Factor (BPFI)

Ball Spin Factor (BSF)

Cage Factor (FTF)

Note on Inputs: The Vibration Factors are geometry-dependent constants derived from the bearing type, Pitch Diameter, Ball Diameter, and Contact Angle. For accurate results, **do not use the default values** but obtain the precise factors from the manufacturer's bearing specification sheet or vibration analysis software documentation.
