Abstract (en)
[origin: WO2006116976A2] The invention relates to a roller bearing (1), with an inner running ring, an outer running ring, several roller bodies (6) arranged between the running rings and guided in a bearing cage (3), whereby the bearing cage (3) has axially aligned cage pins (5) evenly distributed around the circumference, each fixed at one end to a cage ring (4) on each of which a roller body (6) is arranged to rotate on a central bearing drilling (8). According to the invention, the operating properties of the roller bearing (1) may be improved, whereby the roller cage (3) is provided at each cage pin (5) with at least one passive positioning element (10), by means of which the offset of the corresponding roller body (6) may be altered by means of a temperature-dependent change of shape of the positioning element (10).
