Abstract: A linear ball bearing for a carriage in a machine tool has a support with a pair of raceways which oppose a corresponding pair of raceways formed in the carriage. Two endless rows of balls are arranged to circulate in adjacent planes, with the loaded balls rolling between the opposing raceways. One or two rails are fastened to the support for guiding the loaded balls outwardly of the support. The loaded balls of one row mesh in the interstices of the loaded balls of the other row. Each rail has a guiding web for laterally guiding the loaded balls and at least one retaining web for partly encompassing the loaded balls. The longitudinal gaps between the rail and the support have widths less than the ball diameter, thereby blocking the balls from falling out of the support when the bearing is disassembled.

Abstract: Means for determining the state of lubrication in surfaces lubricated by a lubricant and rolling or sliding with respect to one another, provided with a unit for generating a signal dependent upon the capacitance between the lubricated surfaces, characterized by an operating circuit connected to the unit which, in response to the signal dependent upon the capacitance, emits a second signal which is dependent in accordance with a non-linear, for example, exponential, function upon the capacitance between the lubricated surfaces such as that one and the same relative variation in the thickness of the lubricant between the lubricated surfaces results in a fairly great signal variation in the event of decreasing thickness, the second signal being supplied to an integrator which integrates the second signal over an integration period displaced in time and the output signal of which indicates the state of lubrication.

Abstract: In a conveyor incorporating a flexible track (4) being guiding and supported on at least two beams (2, 3), which are angularly adjustable relative to each other, the two beams (2, 3) are arranged in a row after each other with an interspace between them and interconnected to each other by means of a joint.

Abstract: A ball bearing for lengthwise movement has a cage sleeve between a shaft and a housing. The cage sleeve has a plurality of circumferentially distributed channels in which a corresponding row of circulating balls is arranged. The balls loaded by the shaft travel in one linear raceway and return unloaded in another linear raceway, the ends of the linear raceways being connected by a pair of reversing raceways. A load-transmitting raceway rail is seated in each of a plurality of openings in the cage sleeve. Each raceway rail has a raceway groove formed by an inner shoulder and an outer shoulder which overlies the linear raceway for loaded balls, a surface portion which overlies the linear raceway for unloaded balls, and a pair of end surfaces which overlie the respective reversing raceways.

Abstract: A rolling bearing arrangement for supporting a journal of a work roll has two cylindrical rolling bearings for carrying radial loads and an inclined rolling bearing for carrying axial loads arranged between the cylindrical rolling bearings. The rows of rolling bodies of the inclined rolling bearing have radially inwardly directed lines of load transmission and are displaceable on at least one of the respective raceways in both directions transverse to the rolling direction. The end surfaces of the inner ring of the inclined rolling bearing are slidably displaceable in a substantially radial direction on the opposing end surfaces of the inner rings of the cylindrical rolling bearings. The radial play between the inner ring of the inclined rolling bearing and the journal is greater than the radial play between the inner rings of the cylindrical rolling bearings and the journal.
