Abstract
The rotor of a thrust bearing for the horizontal shaft of a centrifugal pump is installed in a housing which is mounted in an oil-containing vessel and has an inlet below and an outlet above the oil level. The peripheral surface of the rotor has a groove which receives a portion of an annular stator to form a suction channel which draws oil from the vessel through the inlet when the shaft is driven. The oil fills the housing and is returned into the supply of oil in the vessel by way of the outlet, a cooling unit and a filtering cartridge.
