Abstract

A rolling-element bearing unit includes at least one outer ring and at least one inner ring, and a plurality of rolling elements between the at least one outer ring and the at least one inner ring. The inner ring has a surface, which may be cylindrical, at an axial end region of the rolling-element bearing unit which surface is configured to contact a seal element. A projection extends radially outwardly from the surface at an angle and forms a guide surface facing the plurality of rolling elements.
