The elastic distortion of journal bearing housings can have a significant influence on the lubricant film thickness and, consequently, upon the oil pressure distribution. The present investigation is aimed at putting orders of magnitude on the housing distortion by finite element methods. The influences of a number of factors on these distortions are illustrated and discussed.
