ada, bA shaft (-) is provided that is rotatably mounted by a journal in a housing in which lubricant mist is provided. One or several outward-extending ribs extend between the journal and shaft sections adjacent to the journal. The shaft is mounted by the journal in the housing using a rolling bearing that is lubricated exclusively by the lubricant mist.
