ABSTRACT:
A system for lubricating a bearing adapted for high rotational speed comprising a stationary and a rotatable race ring and a plurality of rolling elements guided by a cage in the annular space between the rings. The lubricating system for supplying lubricant to the races of the bearing comprises a ring made of a porous material fixed adjacent at least one axial end of the stationary race, an annular lubricant source located adjacent the porous ring which extends into the region of the running surface of the rotating race whereby the lubricant under the influence of negative pressure generated by high rotation is drawn from the lubricant reservoir through the porous ring, circulated through the bearing raceways and rolling elements and returned to the porous ring along the running surface of the stationary race ring.
