Abstract: An annular element for a rolling bearing comprises a cylindrical surface around the circumference of which a groove, the radial and axial depth of which are variable around the circumference, is formed. The cylindrical surface is suitable for being over-moulded with a plastics material to form a body which is fixed firmly for rotation with the annular element and has a plastics projection complementary with the groove. The projection can cooperate with the groove to prevent relative rotation between the annular element and the body.

Abstract: A method and a device for monitoring a bearing arrangement, having at least one bearing, in a mounting element of a roller journal bearing of a roller in a stand of a rolling mill train are designed to initiate upkeep or repair work on the bearing arrangement at the correct time.

Data is transferred between the vibration coupling stud and a vibration monitor. Data stored in the stud may include asset identification code, measuring point identification, prior measurement data, machine or bearing part numbers, and alarm limits.

Abstract: Sealing device (1) for a rolling contact bearing (2) presenting an annular sealing lining (5), a protective shield (6) for the lining (5) which is mounted on the outside of the lining (5) itself, and an encoder (15) which is integral to the shield (6) and which is protected by a covering element (16) arranged opposite the shield (6) in relation to the encoder (15).

Abstract: A method and device for monitoring a bearing arrangement, having at least one bearing, in a housing of a roller journal bearing of a roller in a continuous casting installation are designed to initiate upkeep or repair work on the bearing arrangement at the correct time. The method involves measuring a value of a process quantity at the bearing or in an area adjoining the bearing, providing an evaluation device with the measured value of the process quantity, comparing the measured value with a stored preset value, and triggering a signal as soon as the measured value exceeds or falls below the stored preset value.

Abstract: A method for fixing at least one bearing in a depression of a bearing retainer involves deforming a portion of the bearing retainer to cause a portion of the bearing retainer to form an overlapping connection of the bearing which axially retains the bearing in the depression. In the first stage of the two-stage deformation process, a first partial area of the bearing retainer is deformed compress the material forming the bearing retainer. In the second stage of the deformation process, a second partial area of the bearing retainer is deformed to form the overlapping connection, in the axial direction, between the bearing and the bearing retainer.

Abstract: Sealing device for a flanged bearing for a wheel hub in which the flanged ends (13) of the outer race (11) have the metallic rings (14) of a sealing device (15) pressed on to their internal surfaces; each metallic ring (14) incorporates a rubber element (16) which is suitable for forming a static seal on the outer race of the bearing; the rubber element (16) extends towards the inner race (10) of the bearing (12) to then bend back towards the outside of the bearing itself with an appendix (17), which forms two seals (18 and 19) on the internal surface of a second metallic ring (20); the latter is pressed on to the external surface of the inner race (10) of the bearing; a rubber element (21) is applied to the ring (20) in correspondence with its free end (22) which is axially turned towards the inside of the device; the rubber element (22) presents at least two lips (24 and 25), one of which creates a dynamic seal between the two races (10 and 11) of the bearing together with the above-mentioned lips (24 and 2

Abstract: A tapered roller bearing comprising an outer race, a pair of axially adjacent inner races, and two cages interposed between the inner and outer races to retain two sets of rollers. The radially outer surface of each inner race has, close to the end facing the center of the bearing, a groove able to receive a respective plurality of radially inwardly projecting portions of the parts of the cages disposed close to the center of the bearing so that the cages retain the rollers on the respective inner races during the handling and assembly steps which precede mounting of the sub-units comprising the inner race, cage and rollers into the outer race. A pair of seal devices is fixed to the outer race and interposed between the outer race and each inner race close to the outer sides of the bearing.

Abstract: A railway vehicle wheel always improve damping characteristics when a thin visco-elastic layer is placed between the tire and the connecting disc or ring. The visco-elastic layer improves damping through shearing action and has a thickness that is lower than that of the tire by an order of magnitude.

Abstract: A method for producing a rolling bearing component, in which, before ustenizing, the steel is subjected to cold deformation and quenching is such that the bainitic structure is obtained; and a rolling bearing component produced by the method, such as a rolling bearing ring from 1C to 1,5Cr type series steel, in which at least the surface of the rolling bearing component has a bainitic structure and the service life of the bainitic structure is considerably increased over a component not subjected to cold rolling.
