Abstract

A bearing for a driving shaft of an electrical machine is lubricated by a lubricant. Located between the bearing and rotating parts arranged on the driving shaft is a seal element for lubricant emerging from the bearing. The seal element is configured in the form of a slinger disk by which lubricant emerging from the bearing is returned to the bearing, thus resulting in a closed lubricant circulation. The slinger disk is produced entirely from an elastic material. Lubricant sent off from the slinger disk is returned directly to the bearing.
