K Factor for Ball Bearing from Stribeck's Equation Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
Ball Diameter of a Bearing - (Measured in Meter) - Ball diameter of a bearing refers to the diameter of the ball of a ball bearing.
Number of Balls in Bearing - Number of Balls in Bearing refers to the number of balls that are present in the ball bearing.

STEP 1: Convert Input(s) to Base Unit

Static Load on Bearing: 45000 Newton --> 45000 Newton No Conversion Required
Ball Diameter of a Bearing: 4.2 Millimeter --> 0.0042 Meter (Check conversion here)
Number of Balls in Bearing: 15 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

k = 5*C_o/(d_b^2*z) --> 5*45000/(0.0042^2*15)

Evaluating ... ...

k = 850340136.054422

STEP 3: Convert Result to Output's Unit

850340136.054422 Pascal -->850.340136054422 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

850.340136054422 ≈ 850.3401 Newton per Square Millimeter <-- K Factor
