Pressure bearings differ from circular bearings in that a shrouded step is introduced on the top half, with the intention of improving stability through its antiwhirl properties by increasing the journal eccentricity ratio.
For a well- aligned journal, the film thickness for eccentricity ratio e/c is defined by
Except for certain combinations of high E and eccentricity ratio , the friction factor is mostly lower in isothermal bearings.
Thus, for a bearing with an ellipticity d and eccentricity ratios
Hence the remarks pertaining to the eccentricity ratio, attitude angle, and other operating parameters are applicable to this bearing style also.
