Speed of Rotation of Bearing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Speed of bearing in rpm = Rated Bearing Life*(10^6)/(60*Rated Bearing Life in Hours)
N = L₁₀*(10^6)/(60*L_10h)
This formula uses 3 Variables

Variables Used

Speed of bearing in rpm - Speed of bearing in rpm is the speed or the angular velocity of the bearing in rpm.
Rated Bearing Life - Rated Bearing Life is defined as the total number of million revolutions the bearing rotates before failure.
Rated Bearing Life in Hours - The Rated Bearing Life in Hours is defined as the amount of time in hours the bearing takes to reach its failure.

STEP 1: Convert Input(s) to Base Unit

Rated Bearing Life: 144 --> No Conversion Required
Rated Bearing Life in Hours: 8000 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

N = L₁₀*(10^6)/(60*L_10h) --> 144*(10^6)/(60*8000)

Evaluating ... ...

N = 300

STEP 3: Convert Result to Output's Unit

300 --> No Conversion Required

FINAL ANSWER

300 <-- Speed of bearing in rpm

(Calculation completed in 00.004 seconds)

Radial Factor of Roller Contact Bearing given Race Rotation Factor

Go Radial Factor = (Equivalent dynamic load on bearing-(Thrust Factor for Bearing*Axial or thrust load acting on bearing))/(Race-rotation factor*Radial load acting on bearing)

Radial Load on Bearing given Race Rotation Factor

Go Radial load acting on bearing = (Equivalent dynamic load on bearing-(Thrust Factor for Bearing*Axial or thrust load acting on bearing))/(Radial Factor*Race-rotation factor)

Race Rotation Factor of Roller Contact Bearing

Go Race-rotation factor = (Equivalent dynamic load on bearing-(Thrust Factor for Bearing*Axial or thrust load acting on bearing))/(Radial Factor*Radial load acting on bearing)

Axial Thrust Load on Bearing given Race Rotation Factor

Go Axial or thrust load acting on bearing = (Equivalent dynamic load on bearing-(Radial Factor*Race-rotation factor*Radial load acting on bearing))/Thrust Factor for Bearing

Speed of Rotation of Bearing Formula

Speed of bearing in rpm = Rated Bearing Life*(10^6)/(60*Rated Bearing Life in Hours)
N = L₁₀*(10^6)/(60*L_10h)

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.
