A lubrication conducting element has first and second side parts, each of which creates a sealing lip. The first side part extends to the intermediate part and the second side part extends to the intermediate part. The first and second side parts and the intermediate part form a first cavity with a first opening. Third and fourth side parts each creates a sealing lip. The third side part extends to the intermediate part and the fourth side part extends to the intermediate part. The third and fourth side parts and the intermediate part form a second cavity with a second opening. A hole in the intermediate part facilitates lubrication flow between the first and second cavities. The side parts, the sealing lips, the intermediate part, the cavities and the openings extend rotationally symmetric around a common symmetric axis. |
