Radial Clearance in Terms of Eccentricity Ratio and Minimum Film Thickness of Bearing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radial clearance for bearing = Minimum Film Thickness/(1-Eccentricity Ratio of Journal Bearing)
c = h_°/(1-ε)
This formula uses 3 Variables

Variables Used

Radial clearance for bearing - (Measured in Meter) - Radial clearance for bearing is a measured value of the total movement of one ring relative to the other in a plane perpendicular to the bearing axis.
Minimum Film Thickness - (Measured in Meter) - Minimum film thickness is the lowest amount of the thickness of the oil film formed inside the sliding bearing.
Eccentricity Ratio of Journal Bearing - Eccentricity Ratio of Journal Bearing is the ratio of the eccentricity of the journal bearing's inner race to the radial clearance.

STEP 1: Convert Input(s) to Base Unit

Minimum Film Thickness: 0.013 Millimeter --> 1.3E-05 Meter (Check conversion here)
Eccentricity Ratio of Journal Bearing: 0.49 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

c = h_°/(1-ε) --> 1.3E-05/(1-0.49)

Evaluating ... ...

c = 2.54901960784314E-05

STEP 3: Convert Result to Output's Unit

2.54901960784314E-05 Meter -->0.0254901960784314 Millimeter (Check conversion here)

FINAL ANSWER

0.0254901960784314 ≈ 0.02549 Millimeter <-- Radial clearance for bearing
