A roller bearing according to  claim 2 , wherein the rocking motion of the plane of the track base is characterized, when laterally viewing the rotational axis, by two end positions having maximal inclination relative to the rotational axis, and the track element is formed such that the end positions of the planes of the shoulders or rims are reached in an advanced or lagging manner by a predetermined angle as compared to the end positions of the plane of the track base. 
     
     
         4 . A roller bearing according to  claim 3 , wherein the end positions of the planes of the two shoulders or the rims are different from each other. 
     
     
         5 . A roller bearing according to  claim 4 , wherein the center points of the circumferential lines of both shoulders or rims are disposed in a point symmetric manner relative to a center point of the circumferential line of the track base. 
     
     
         6 . A roller bearing according to  claim 5 , wherein the roller bearing comprises at least two track elements, between which the roller bodies are disposed, and the track elements are formed in a manner corresponding to each other. 
     
     
         7 . A roller bearing according to  claim 6 , wherein at least one circumferential portion of one of the track elements is provided to transfer a force onto at least one additional structural element. 
     
     
         8 . A roller bearing according to  claim 7 , wherein the track element comprises an extension in said circumferential portion. 
     
     
         9 . A roller bearing according to  claim 8 , wherein the extension is attached by friction welding. 
     
     
         10 . A roller bearing according to  claim 9 , wherein the center points of the circumferential lines of both shoulders or rims lie offset relative to a straight line that extends through the center point of said circumferential portion and the center point of the circumferential line of the track base. 
     
     
         11 . A roller bearing according to  claim 10 , wherein the roller bodies are formed as balls. 
     
     
         12 . A roller bearing comprising:
 at least one track element including a track having a track base and first and second shoulders disposed on opposite sides of the track base as viewed in an axial direction of the roller bearing, the circumferences of the track base, first shoulder and second shoulder each being circular, the three respective circles defining three respective planes, and   at least one set of roller bodies disposed in an annular manner around the track base,   wherein the track base, first shoulder and second shoulder are configured such that, as viewed perpendicular to the planes defined by the respective circles, the center points of the three circles do not overlap.   
     
     
         13 . A roller bearing according to  claim 12 , wherein the track element is configured to rotate about a rotational axis that is oblique relative to the planes so that the plane of the track base performs a rocking motion relative to the rotational axis during each revolution of the track element. 
     
     
         14 . A roller bearing according to  claim 13 , wherein the rocking motion of the plane of the track base is bounded, when viewed laterally to the rotational axis, by two end positions having maximal inclination relative to the rotational axis, and the track element is formed such that the end positions of the planes of the shoulders are reached in an advanced or lagging manner by a predetermined angle as compared to the end positions of the plane of the track base. 
     
     
         15 . A roller bearing according to  claim 14 , wherein the respective end positions of the planes of the first and second shoulders are different from each other. 
     
     
         16 . A roller bearing according to  claim 12 , wherein the center points of the circles defined by the circumferences of the first and second shoulders are disposed in a point symmetric manner relative to the center point of the circle defined by circumference of the track base. 
     
     
         17 . A roller bearing according to  claim 12 , wherein the roller bearing comprises at least two track elements, between which the roller bodies are disposed, and the track elements are formed in a manner complementary to each other. 
     
     
         18 . A roller bearing according to  claim 17 , further comprising an extension projecting from a circumferential portion of one of the track elements, the extension being configured to transfer a reciprocating force to at least one additional structural element. 
     
     
         19 . A roller bearing according to  claim 18 , wherein the circles defined by the circumferences of the first and second shoulders lie offset relative to a straight line that extends through the center point of said circumferential portion and the center point of the circle defined by the circumference of the track base. 
     
     
         20 . A roller bearing according to  claim 19 , wherein the center points of the circles defined by the circumferences of the first and second shoulders are disposed in a point symmetric manner relative to the center point of the circle defined by circumference of the track base.
