Abstract

Permanent electro-conductive connection is achieved between a bearing component and a baseplate/flange by providing at least one solid-state contact element between the baseplate/flange and the bearing component. The contact element establishes an electric contact between these parts by exercising mechanical force on the baseplate/flange and/or the bearing component. Alternatively, at least one welding seam may be formed between the baseplate/flange and the bearing component to establish the electro-conductive connection.
