Minimum Film Thickness given Radius of Bearing Solution

STEP 0: Pre-Calculation Summary

Formula Used

Minimum Film Thickness = Radius of Bearing-(Eccentricity in bearing+Radius of Journal)
h_° = R-(e+r)
This formula uses 4 Variables

Variables Used

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.
Radius of Bearing - (Measured in Meter) - The Radius of Bearing is the sum of the radius of the journal and radial clearance of a bearing.
Eccentricity in bearing - (Measured in Meter) - Eccentricity in bearing is the displacement of the journal from the bearing.
Radius of Journal - (Measured in Meter) - The Radius of Journal is the radius of the journal (which rotates freely in a supporting metal sleeve or shell).

STEP 1: Convert Input(s) to Base Unit

Radius of Bearing: 26 Millimeter --> 0.026 Meter (Check conversion here)
Eccentricity in bearing: 0.011 Millimeter --> 1.1E-05 Meter (Check conversion here)
Radius of Journal: 25.5 Millimeter --> 0.0255 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_° = R-(e+r) --> 0.026-(1.1E-05+0.0255)

Evaluating ... ...

h_° = 0.000489

STEP 3: Convert Result to Output's Unit

0.000489 Meter -->0.489 Millimeter (Check conversion here)

FINAL ANSWER

0.489 Millimeter <-- Minimum Film Thickness

(Calculation completed in 00.020 seconds)
