Rolling contact bearings with a greatly increased service life.

摘要

Roller bearings (300) for receiving of radial and / or axial loads with a first and a second bearing ring (302, 304), between which the rolling elements (301) at least one row are received, characterized in that axially in the region of the center of mass (311) of the rolling bodies (301) on the roller elements and on two bearing rings (302, 304) cooperating holding means (306, 307, 308) are made or arranged, by means of which roller body related axial forces of a bearing ring via the roller bodies (301) on the other bearing ring are also able to be transmitted, in the rolling surface (310) of the rolling bodies (301) in each case an all-round wälzkörpernut (313) is formed that, in two bearing rings (302, 304) in each case have a radially circumferential and to the rolling elements (301) pointing bearing annular groove (307, 308) is formed, and in that, in order to at least one-sided axial guidance of the rolling bodies (301) in the rolling bodies grooves (313) and in the two bearing ring grooves (307, 308) a ring body (306) is arranged.
