Abstract: An outer ring for a roller bearing includes a raceway produced from a bearing steel. The outer ring is made of a metal strip wound to form a raceway tube and a cladding tube which is connected thereto and which surrounds the raceway tube on the outer side.

Abstract: A running ring (1) for a sleeve bearing, the running ring substantially including a cylindrical outer casing (3) or inner casing, the inner circumferential surface (5) or outer circumferential surface of which is formed as a raceway for bearing rollers, and two rims, which are formed on the axial end faces of the outer casing (3) or the inner casing and are oriented radially inward (7, 8) or outward, said rims being provided as an axial guide for the bearing rollers.

Abstract: A needle sleeve, in particular for pivotably mounting the throttle valve shaft of a control device for recirculating exhaust gas in internal combustion engines. The needle sleeve provides a thin-walled outer ring formed without cutting. A needle roller and cage assembly is inserted in the outer ring. The needle cage carries the bearing needles at uniform spacings in the circumferential direction. The needle sleeve has, at its axial sides, two radially inward facing ribs holding the needle roller and cage assembly in the outer ring and has multiple seals that seal the sleeve to prevent exhaust gas condensates from flowing through. The outer ring of the needle sleeve is a rimless, cylindrical sleeve, and the seals are two lip sealing rings having an S-shaped cross-sectional profile. The seals are located at least partially outside the outer ring and are pressed onto its axial edges, and provide the radially inward facing ribs.

According to the invention, the outer ring (16) is made of a metal strip (1, 5) wound to form a raceway tube (4, 12, 14) 5) and a cladding tube (9, 13, 15, 17) which is connected thereto and which surrounds the raceway tube (4, 12, 14) on the outer side.

Abstract: A rolling bearing comprising a rolling bearing cage having a plurality of rolling element pockets arranged in at least one row to receive at least one row of rolling elements, two lateral rings and a plurality of crosspieces connecting the two lateral rings, such that the plurality of rolling element pockets are formed between the plurality of crosspieces, and at least one empty pocket. The rolling bearing cage includes fewer rolling elements in the at least one row than the number of rolling element pockets, such that the at least one empty pocket does not receive a rolling element. A method for producing a rolling bearing cage is also provided.

Abstract: A radial roller bearing comprises a smooth cylindrical outer ring inserted in a housing with a roller race arranged in the outer ring. The roller race is formed by a plurality of roller-shaped rolling elements inserted in a bearing cage, which holds said rolling elements evenly spaced in a circumferential direction. The rolling elements roll off an outer raceway formed by the inner shell surface of the outer ring, and off an inner raceway formed by the outer shell surface of a shaft to be mounted, or formed by a smooth cylindrical inner ring fitted onto the shaft. The axial guidance of the roller race is accomplished by way of two separate flanged rings abutting the axial sides of the outer ring which, together with the outer ring are axially fixed in place by way of safety elements engaging with circumferential grooves in the housing. The safety elements for the flanged rings and the outer ring, and the flanged rings are fixedly connected.

Abstract: A bearing ring for a radial rolling bearing, in particular for a cylindrical roller bearing or needle bearing which has, on one of the radial surface areas thereof, a track for a set of cylindrical rolling bodies which are cageless or are guided by a cage and one or two guide flanges axially bounding the track of the rolling bodies is/are fastened to the axial end surfaces of said bearing by adhesive bonding. Each guide flange has a rectangular profile cross section with a horizontal fastening limb and a vertical flange limb and, by way of the horizontal fastening limb thereof, is adhesively bonded in an encircling axial groove in an axial end surface of the bearing ring.

Abstract: The invention concerns a rolling element cage (32) made of a metal strip material that is profiled, stamped, cut to length, and bent into a round shape, wherein the ends of the cut-to-length strip sections are joined together by welding. In order to make it possible to influence the lubricant distribution in the bearing and the vibration characteristics of the cage and thus of the overall bearing system, according to the invention the strip section ends (34, 36) are joined together with a predetermined axial offset (a) and/or radial offset (b).

Abstract: When an ignition system is installed, the spatial position of an ignition device (5a to 5g) in relation to the surrounding, its geographical position, is as yet not determined. The user is required to exercise extreme caution in order to ensure that the ignition devices (5a to 5g) connect to the ignition system (1) in accordance with a predetermined blasting plan. A specially trained person must therefore systematically carry out the sequential connection (compulsory sequence) of each ignition device (5a to 5g) to the bus line (3) of the ignition system. i.e. logging. The person connecting the ignition devices must execute the ignition of device programming operation in all kinds of conditions, in open country, with utmost caution. This represents a considerable time delay for a blast. If one ignition device is overlooked during logging, the already entered data have to be reprogrammed, which costs time.

Abstract: Errors may occur in a detonating system that consists of several detonating circuits when the connection—the logging-on—of detonators is effected to the buses of a logger which in turn is connected to a blaster. Connecting is effected, particularly in opencast-mining operations, under conditions that may lead to damage, not visible at first, in particular to the insulation of the detonators and also of the detonating lines. Errors may occur in the transmission of data, for example as a result of loss or falsification of the signals to be transmitted or as a result of intrusion of signals from an extraneous detonator. In accordance with the invention it is therefore proposed that a log-on manager is installed which is in bidirectional contact with the loggers, with the blaster and with the log-data communicators of the loggers which signal the data pertaining to the detonators to the logger.
