Moisture-tight ball-bearing e.g. for electric motor of automatic braking system in motor vehicle

摘要

A ball-nearing (1-6) axially or radially, moisture-tight mounted in a bearing housing, is sealed against axial ingress of moisture by a sealing washer (5) fixed tight against an outer bearing ring (1) and positioned tight-against its inner bearing ting (2) or by a sealing ring fixed tight against the inner bearing ring (1), axially on the outside in the region between its outer bearing ring (1) on one side, and its inner ring (1), on the other side. The outer bearing ring (1) is sealed against radial ingress of moisture relative to its bearing housing, by at least one sealing lip (5.1,5.2), on the axial outer end-face of the sealing washer (5) and pressing against the bearing housing.
