PURPOSE: A brush seal is provided to prevent the separation of oil mist outside a bearing cavity by combining with a rotatable shaft. CONSTITUTION: A rotatable shaft is mounted in an oil bearing and generates oil mist. One or more brush seals(24) are carried by the bearing housing(22) for substantially sealing the oil mist in the bearing cavity from migration outwardly. The bristles(30) have a diameter in the range of .5 to 1.0 mils, preferably about .56 mils. The bristles have a stiffness less than 1 psi/mil and preferably about .2 psi/mil. The brush seal may be mounted on a sheet metal mounting plate, enabling an inexpensive securement of brush seals to the housing. Thereby, the brush seal seals the bearing cavity to prevent the outflow of the oil mist with low costs.
