Abstract

A rolling-element bearing with line contact includes bearing inner and outer parts having running surfaces, and at least one rolling element is disposed between and makes line contact with the bearing inner and outer parts. A width of the outer running surface and/or a width of the inner running surface is narrower at least in a first circumferential partial region than a length of the rolling-element, and in the first partial region the bearing outer part running surface and/or the bearing inner part running surface extends obliquely to a rolling direction of the at least one rolling element.
