Eccentricity ratio in bearing
http://www.epi-eng.com/piston_engine_technology/engine_bearings.htm WebMay 31, 2024 · Radial eccentricity ratio is ɛ = e r / h ro. Axial film thickness is X ¯ = h a / h ao so that axial displacement ratio is 1 - X ¯. Minimum film thickness is h min = ( 1 - ɛ) X ¯. h o. The shaft is assumed to be displaced to a fixed eccentric position.
