Bearing with improved resistance to micropitting

A bearing comprising:

• a plurality of rolling elements arranged between an inner raceway and an outer raceway of the bearing;
• and
• a rolling contact interface being defined between a first rolling contact surface on at least one rolling element and a second rolling contact surface formed by one of the inner and outer raceways,
• wherein the first rolling contact surface has a first RMS roughness Rq1 and a first roughness pattern γ1, expressed in terms of the Peklenik number;
• and
• wherein the second rolling contact surface has a second RMS roughness Rq2 and a second roughness pattern γ2, expressed in terms of the Peklenik number,
• wherein the rolling contact interface has a surface topography in which:
• (a) the first roughness pattern γ1 of the first rolling contact surface and the second roughness pattern γ2 of the second rolling contact surface are oriented in the direction of rolling (x), whereby γ1≧3.0 and γ2≧10.0;
• and
• (b) the first rolling contact surface and the second rolling contact surface have a substantially equal RMS roughness, whereby 0.8≦Rq1/Rq2≦1.25.
