Abstract: An oil lubrication system for a bearing positioned between two rotatable shafts, especially a pilot bearing (1) for a main shaft (3) in a transmission. The lube oil is fed predominantly radially inwardly on one side (11) of the pilot bearing (1) and is radially drained outwardly on the other side (12) via an annular drainage passage (8) located between the two shafts. An elastic rubber seal (4) is situated in the drainage passage (8) which, during operation, is opened by the centrifugal force or by the pressure of the lube oil pumped through the system and closes the drain passage (8) during downtime of the transmission. The elastic rubber seal (4) can be fastened to the input shaft (2) via a body (44) especially when the sealing lip (41) is to be opened by the centrifugal force. In addition, fastening to the main shaft (3) is also possible when the sealing lip is to be predominantly opened by the oil lube pressure pumped to the pilot bearing (1).
