Nominal Life of Roller Contact Bearing Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Nominal Life in Millions of Kilometers - Nominal Life in Millions of Kilometers is defined as the distance traveled by the wheel in million km.
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.

STEP 1: Convert Input(s) to Base Unit

Rated Bearing Life: 144 --> No Conversion Required
Train Wheel Diameter: 880 Millimeter --> 0.88 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_10s = L₁₀/(1000/(pi*D)) --> 144/(1000/(pi*0.88))

Evaluating ... ...

L_10s = 0.398102621062899

STEP 3: Convert Result to Output's Unit

0.398102621062899 --> No Conversion Required

FINAL ANSWER

0.398102621062899 ≈ 0.398103 <-- Nominal Life in Millions of Kilometers

What is a rolling contact bearing?

The term rolling contact bearings refers to the wide variety of bearings that use spherical balls or some other type of roller between the stationary and the moving elements. The most common type of bearing supports a rotating shaft, resisting purely radial loads or a combination of radial and axial (thrust) loads.

How to Calculate Nominal Life of Roller Contact Bearing?

Nominal Life of Roller Contact Bearing calculator uses Nominal Life in Millions of Kilometers = Rated Bearing Life/(1000/(pi*Train Wheel Diameter)) to calculate the Nominal Life in Millions of Kilometers, Nominal Life of Roller Contact Bearing is essentially the length of time a bearing can be expected to perform as required in predefined operating conditions. It is based primarily on the probable number of rotations a bearing can complete before it starts showing symptoms of fatigue, such as spalling or cracking due to stress. Nominal Life in Millions of Kilometers is denoted by L_10s symbol.

How to calculate Nominal Life of Roller Contact Bearing using this online calculator? To use this online calculator for Nominal Life of Roller Contact Bearing, enter Rated Bearing Life (L₁₀) & Train Wheel Diameter (D) and hit the calculate button. Here is how the Nominal Life of Roller Contact Bearing calculation can be explained with given input values -> 0.398103 = 144/(1000/(pi*0.88)).

FAQ

What is Nominal Life of Roller Contact Bearing?

Nominal Life of Roller Contact Bearing is essentially the length of time a bearing can be expected to perform as required in predefined operating conditions. It is based primarily on the probable number of rotations a bearing can complete before it starts showing symptoms of fatigue, such as spalling or cracking due to stress and is represented as L_10s = L₁₀/(1000/(pi*D)) or Nominal Life in Millions of Kilometers = Rated Bearing Life/(1000/(pi*Train Wheel Diameter)). Rated Bearing Life is defined as the total number of million revolutions the bearing rotates before failure & Train Wheel Diameter is the distance measured across the face of the wheel, from bead seat to bead seat.

How to calculate Nominal Life of Roller Contact Bearing?
