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*Co/(db^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
