Aug 04, 2017 · Pressure Dam bearings are essentially a plain journal bearing with a pocket cut in one half that has an abrupt stop at some point in the shell. Viscous and inertia effects result in a buildup of pressure at the dam, this localized high pressure area creates an artificial load on the shaft that helps stabilize the rotor.
