Abstract

A shaft (1a-d) is provided that is rotatably mounted by a journal (2) in a housing (4) in which lubricant mist is provided. One or several outward-extending ribs (6) extend between the journal and shaft sections (5a, 5b) adjacent to the journal. The shaft is mounted by the journal in the housing using a rolling bearing (3) that is lubricated exclusively by the lubricant mist. At least one of the ribs associated with the journal extends at a certain angle of attack (11, 12) to the axis of rotation of the shaft and is used as a blade for conveying the lubricant mist into the rolling bearing.
