Rated Bearing Life in Million Revolutions given Nominal Life Solution

STEP 0: Pre-Calculation Summary

Formula Used

Rated Bearing Life = (1000/(pi*Train Wheel Diameter))*Nominal Life in Millions of Kilometers
L₁₀ = (1000/(pi*D))*L_10s
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Rated Bearing Life - Rated Bearing Life is defined as the total number of million revolutions the bearing rotates before failure.
Train Wheel Diameter - (Measured in Meter) - Train Wheel Diameter is the distance measured across the face of the wheel, from bead seat to bead seat.
Nominal Life in Millions of Kilometers - Nominal Life in Millions of Kilometers is defined as the distance traveled by the wheel in million km.

STEP 1: Convert Input(s) to Base Unit

Train Wheel Diameter: 880 Millimeter --> 0.88 Meter (Check conversion here)
Nominal Life in Millions of Kilometers: 0.4 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L₁₀ = (1000/(pi*D))*L_10s --> (1000/(pi*0.88))*0.4

Evaluating ... ...

L₁₀ = 144.686311901723

STEP 3: Convert Result to Output's Unit

144.686311901723 --> No Conversion Required

FINAL ANSWER

144.686311901723 ≈ 144.6863 <-- Rated Bearing Life

(Calculation completed in 00.004 seconds)
