Number of Balls of Ball Bearing from Stribeck's Equation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Balls in Bearing = 5*Static Load on Bearing/(K Factor*Ball Diameter of a Bearing^2)
z = 5*C_o/(k*d_b^2)
This formula uses 4 Variables

Variables Used

Number of Balls in Bearing - Number of Balls in Bearing refers to the number of balls that are present in the ball bearing.
Static Load on Bearing - (Measured in Newton) - Static Load on Bearing is the load acting onto the bearing when the bearing is not rotating or the bearing is in static condition.
K Factor - (Measured in Pascal) - K Factor is the constant that depends upon the radii of curvature at the point of contact and on the moduli of elasticity of materials.
Ball Diameter of a Bearing - (Measured in Meter) - Ball diameter of a bearing refers to the diameter of the ball of a ball bearing.

STEP 1: Convert Input(s) to Base Unit

Static Load on Bearing: 45000 Newton --> 45000 Newton No Conversion Required
K Factor: 850 Newton per Square Millimeter --> 850000000 Pascal (Check conversion here)
Ball Diameter of a Bearing: 4.2 Millimeter --> 0.0042 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

z = 5*C_o/(k*d_b^2) --> 5*45000/(850000000*0.0042^2)

Evaluating ... ...

z = 15.0060024009604

STEP 3: Convert Result to Output's Unit

15.0060024009604 --> No Conversion Required

FINAL ANSWER

15.0060024009604 ≈ 15.006 <-- Number of Balls in Bearing
