Abstract
A non-contact sealing system for shaft bearings lubricated with lubricating fluid employs a centrifugal pressurizing seal having a stator ring and a rotor ring with a centrifugal pressure chamber to pressurize the fluid and deliver the fluid to remote portions of a bearing through channels in the bearing housing. The system enables bearings to be lubricated at stations remote from the system as well as bearings supporting shafts oriented in the vertical direction.
