Definitions

• the present invention is concerned with rolling bearings, and in particular with a new cage concept or with a concept that makes it possible, the plurality of rolling elements in a To hold bearings relative to each other in a defined minimum distance.
• a spacer 8 is arranged in each case to prevent the adjacent rolling elements 6 touch directly.
• the minimum distance, which is ensured by the use of the spacer elements 8, is dependent on the geometry of the spacer elements 8 and in particular can be kept extremely small.
• the minimum distance between adjacent rolling elements 6 occurs here approximately at a bearing pitch circle, which is defined by an idealized circle, which passes through the centers of the individual balls 6 and whose center is located on the axis of rotation of the bearing.
• the selected spacing element 9 can be guided during operation of the bearing both on the shoulder, that is to say on an outer annular shoulder 16 or an inner annular shoulder 18, and also on the raceway, that is to say through the recess 14.
• the selected spacing element 9 or a spacing element 8 can be used in alternative embodiments Also extend to more than one in Fig. 3 shown extension length 20 in the recess, so that the tread of the selected spacer element 9 touched and can be used for leadership.
• the selected 9 can also be used vice versa, so that it does not extend into the raceway of the bearing inner ring 2 but into the raceway of the bearing outer ring 4.
• a radial distance 22 between the selected spacer 9 and the surface of the raceway is greater than 0 in order to avoid raceway guidance.
