Abstract
A sealed bearing system for rotatably journaling a shaft relative to a surrounding housing by means of bearing assemblies each comprising a pocket secured to the housing and a bearing support secured to the shaft, the bearing support extending into the pocket with bearings interposed between the bearing support and the walls of the pocket; a lubricant is sealed in the pocket by sealing rings extending between the bearing support and the walls of the pocket; the bearing assemblies are provided in opposing pairs with flow restrictor means lying between the bearing assemblies, thereby forming a system which permits fluid flow between the shaft and the housing but which seals the bearings from infiltration of the fluid irrespective of pressure variation in the flowing fluid.
