1. Wälzlagerteil, insbesondere Wälzlageraußenring (1), Wälzlagerinnenring (2) oder Wälzkörper (3), das an einer über seinen Umfang (U) verlaufenden Kontaktfläche (4) mit einem anderen Wälzlagerteil (1, 2, 3) in Berührungskontakt steht, dadurch gekennzeichnet, daß das Wälzlagerteil (1, 2, 3) an der Kontaktfläche (4) Mikronuten (5) aufweist, die sich im wesentlichen über den gesamten Umfang (U) der Kontaktfläche (4) erstrecken, wobei eine Vielzahl von Mikronuten (5) im wesentlichen parallel zueinander angeordnet sind.1. Rolling bearing part, in particular rolling bearing outer ring ( 1 ), rolling bearing inner ring ( 2 ) or rolling element ( 3 ) which is in contact with another rolling bearing part ( 1 , 2 , 3 ) on a contact surface ( 4 ) extending over its circumference (U), thereby characterized in that the roller bearing part ( 1 , 2 , 3 ) on the contact surface ( 4 ) has micro grooves ( 5 ) which extend essentially over the entire circumference (U) of the contact surface ( 4 ), a large number of micro grooves ( 5 ) are arranged substantially parallel to each other. 2. Wälzlagerteil nach Anspruch 1, dadurch gekennzeichnet, daß die Mikronuten (5) eine Tiefe (t) von 0,1 µm bis 30 µm aufweisen.2. Rolling bearing part according to claim 1, characterized in that the micro grooves ( 5 ) have a depth (t) of 0.1 µm to 30 µm. 3.

Rolling bearing part according to one of claims 1 to 4, characterized in that a plurality of micro-grooves ( 5 ) arranged next to one another are substantially geometrically identical. 6. Wälzlagerteil nach einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß neben den im wesentlichen parallel zueinander verlaufenden Mikronuten (5) weitere Mikronuten (6, 7) auf der Kontaktfläche (4) vorhanden sind, die kreuzförmig zueinander angeordnet sind.6. Rolling bearing part according to one of claims 1 to 5, characterized in that in addition to the substantially parallel micro grooves ( 5 ) there are further micro grooves ( 6 , 7 ) on the contact surface ( 4 ) which are arranged in a cross shape to one another. 7. Wälzlagerteil nach Anspruch 6, dadurch gekennzeichnet, daß die Tiefe (t) der kreuzförmig zueinander verlaufenden Mikronuten (6, 7) kleiner als diejenige der im wesentlichen parallel zueinander verlaufenden Mikronuten (5), vorzugsweise höchstens 50% hiervon, ist.7. Rolling bearing part according to claim 6, characterized in that the depth (t) of the cross-shaped micro grooves ( 6 , 7 ) is smaller than that of the substantially parallel micro grooves ( 5 ), preferably at most 50% thereof. 8. Wälzlagerteil nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, daß die Mikronuten (5) durch einen Honvorgang eingebracht sind, bei dem das Wälzlagerteil (1, 2, 3) im wesentlichen nur mit einer Rotationsbewegung und im wesentlichen ohne Axialbewegung das Honwerkzeug kontaktiert.8. Rolling bearing part according to one of claims 1 to 7, characterized in that the micro grooves ( 5 ) are introduced by a honing process in which the rolling bearing part ( 1 , 2 , 3 ) essentially only with a rotational movement and essentially without axial movement of the honing tool contacted.
