Title: Radial roller bearing, in particular a single-groove grooved ball bearing

Abstract: A radial roller bearing, which is a single-grooved ball bearing. The bearing bodies are spherical disks with two symmetrical, parallel lateral surfaces from a spherical base shape. The bearing has a larger contact surface of the spherical disk in relation to the bearing body tracks thereof, as well as, an increased number of bearing bodies. One part of the width of the disks, between the lateral surfaces thereof, is larger than the distance between the inner side of the external bearing ring and the external side of the inner bearing ring, but equal to or smaller than the width of the bearing body tracks. Also, the use of the disks in the bearing takes place according to an eccentric mounting method where the disks are arranged in a transversal manner in the bearing body tracks and are arranged on top of each other in relation to the lateral surfaces thereof.
