Abstract
A rolling element bearing comprises an inner ring, an outer ring and a series of rolling elements the rolling surface of which is in contact with the raceway surfaces of both rings, and possibly at least one flange the surface of which is in slidable contact with the end surface of a roller element, at least one of these surfaces (8) being provided with a topography comprising recesses (13) which are generally isolated from each other by lands (14) and which may contain a lubricant. The recesses have a maximum size of 100 micrometer in a direction parallel to the surface in question.
