A positive displacement lubrication system is disclosed that includes a rotatable shaft, a bearing, and a centrifugal force generating lubrication member that is mounted on the shaft for rotation with the shaft. The centrifugal force generator is spaced from the bearing member. A labyrinthine lubricant flow passage extends from the bearing, through a space between the bearing and the centrifugal force generating member, to the outlet member. Among other things, the system and method provides an efficient method of actively managing bearing lubrication and removal of lubricant, while also acting to seal off bearing areas from leaking. The positive displacement devices can be used for both grease and oil mist lubrication systems. They can also operate under heavy thrust loads when used to support the bearings.
