ABSTRACT:
A rotating shaft motor or cartridge incorporates an o-ring which surrounds the rotating shaft and is borne on a carrier. As supported on the carrier, the o-ring does not normally block the bearing passages which would prevent the smooth distribution of oil throughout the motor. However, the carrier and o-ring combination are designed to allow the o-ring to be forced into an opening between the shaft and sleeve for completely sealing the remaining portion of the bearing during filling. The rotating shaft includes a central reservoir, having one or more grooves or passages communicating with the hydrodynamic bearing surfaces and ending in a septum or rubber plug which is inserted in an opening in the shaft.
