Abstract: A method for marking multiple components, each of which has at least one transponder and a storage device. A first marked component comes in contact with second components disposed in the range thereof and transmits information to them. The components mark themselves while taking the information transmitted by the first component into consideration. At least one second component after the marking thereof comes in contact with further components in the range thereof that are not marked yet in order to bring about the marking thereof. A group of components marked in this way, a corresponding container for carrying out the method, and a rolling bearing, which is a possible component to be marked in this way, are also disclosed. As a result, the self-organization and marking of a group of components is achieved with the help of an interconnected network.

Abstract: A rolling bearing which has at least one heated rolling bearing ring. An electrical heating element is applied with good thermally-conductive contact to a surface section of the heated rolling bearing ring. The heat quantity which can be generated by the heating element is dimensioned such that the heated rolling bearing ring undergoes thermal expansion when heated, which permits the rolling bearing to be mounted on a frame element with the formation of a shrink fit during subsequent cooling.

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

Abstract: The invention relates to a measuring device, comprising an optical sensory array for determining changes in the position of a drum which is mounted in a washing machine at least so as to be pivotable about a swiveling axis. The sensory array is provided with at least one light sensor, at least one modifiable light passage, and at least one light source. The light sensor is directed to portions of light which are emitted by the light source, are dependent upon changes in the light passage, and impinge the light sensor.

Abstract: The invention relates to a radial roller bearing, having an outer bearing ring and an inner bearing ring, and rolling bodies located between the rings. Some of the rollers are formed by individual hollow rollers of a shape memory alloy. The cross-section of the shape memory alloy rollers is deformed during the assembly of the radial roller bearing to fit the dimensions of the free space between the rims of the rings. The rollers are introduced into the radial roller bearing through the free space between the rims of the bearing rings. After introduction into the radial roller bearing and once they have reached a specific temperature, the rollers independently regain their original shape.

A partial quantity of the rolling bodies is made of a shape memory alloy, the cross-section of the bodies being deformed to fit the dimensions of the free space between the rims. After introduction into the bearing and once they have reached a specific temperature, the bodies regain their original shape.
