Abstract: A bearing comprising a plurality of rolling elements arranged between an inner raceway (12) and an outer raceway (22) of the bearing, whereby a rolling contact interface is defined between a first rolling contact surface (31) on at least one rolling element and a second rolling contact surface formed by one of the inner and outer raceways (12, 22). The first rolling contact surface has a first RMS roughness R q1 and has a first roughness pattern y i , expressed in terms of the Peklenik number y. The second rolling contact surface has a second RMS roughness R q2 and has a second roughness pattern y 2 . To minimise micropitting in the bearing, the rolling contact interface has a surface topography in which: - the roughness pattern of the first and of the second rolling contact surfaces are oriented in the direction of rolling, whereby γ 1 ≥ 3.0 and Y 2 ≥ 10.0; and - the first and of the second rolling contact surfaces have substantially equal roughness heights, whereby 0.8 q1 /R q2 ≤ 1.25

Abstract: The present invention relates to a roller bearing for use in applications where the bearing experiences sliding at a rolling contact interface in a direction (y) transverse to the direction of rolling (x). The bearing comprises an inner ring, an outer ring and at least one set of rollers, disposed between an inner raceway (113) of the bearing inner ring and an outer raceway of the bearing outer ring, wherein an outer surface of at least one roller is defined as a first rolling surface; at least one of the inner raceway (113) and the outer raceway is defined as a second rolling contact surface; and one of the first and second rolling contact surfaces has a greater surface roughness than the other of the first and second rolling contact surfaces, According to the invention, the rougher of the first and second rolling contact surfaces is provided with a first roughness lay with an orientation angle Θ relative to the direction of rolling of between 0 and 90°.
