The rolling bearing has an inner rolling track (2) of the inner ring (1) having a profile selected between a logarithmic profile and a mixed logarithmic profile, a sliding track (18) between the inner ring and the head of the rolling elements having a straight or slightly bulged geometry, a rolling track (5) of the rolling element (4) having a standard bulged profile or a mixed logarithmic profile, an outer rolling track (7) of the outer ring (6) having a special bulged profile and a cage (3) between the inner (1) and outer (6) rings. The contacts are optimised and the friction is reduced on these contact surfaces of the rolling tracks with the rolling elements.
The present invention relates to the application of texture to promote elastohydrodynamic lubrication, hydrodynamic lubrication and boundary lubrication on surfaces subjected to friction in a roller bearing, i.e. the rolling track of the inner race, the rolling track of the outer race and the outer face of the rollers. The texture is defined by dimples or holes with a regular or irregular geometric shape, evenly distributed in all directions across the surface in a particular pattern.
The present invention relates to a pre-assembled unit having two tapered roller bearings, for a driven shaft designed to be replaced efficiently and to maintain optimal tightness as if it were factory assembled. The bearing comprises a rubber seal attached to the lateral face of the inner race of one of the tapered rollers, said face being opposite the smooth face of the other tapered roller. The necessary widening of the inner races requires a second invention, namely, a roller cage that allows the rollers to rock slightly in order to be assembled without causing or becoming damaged.
The invention relates to a system for monitoring bearings, preferably for roller bearings having a first bearing ring and a second bearing ring mounted such as to rotate relative to one another, said system comprising at least one sensor element including one or more sensors for the contactless detection of the state of the bearings, at least one transmitter for transmitting a signal, and a power unit for supplying power to the sensor element and the transmitter, in which a sensor element is connected to the transmitter and mounted in a supporting element that is fitted to the bearing using an adapter. The resulting bearing-monitoring system is a system which can be installed in a simple and cost-effective manner and which can be retrofitted to almost any type of bearing.
The invention relates to a sensorized wheel hub suitable for heavy goods vehicles, comprising an electronic device that can measure various critical parameters, such as temperature, mileage, speed, vibrations, moisture, load, etc.,while withstanding the conditions of the environment and without altering the data collected, so as to supply the data required, in order to monitor the condition of the bearing coupled to the sensorized wheel hub from its installation to the end of its service life.
The invention relates to a bearing for a drive pinion (6), which comprises a casing (2) and two single-row tapered roller bearings (1) joined together by the inner bearing races (4, 5) thereof by means of a ring (3), the ring (3) being positioned between the ends of the inner races (4, 5) and the peripheral surface of the shaft of the drive pinion (6). This arrangement of the joining ring (3) makes it simpler to operate and check the assembly of the unit and facilitates occasional dismantling, since the arrangement prevents the ring from breaking when the shaft the drive pinion (6) is removed.
The invention relates to a bearing assembly, with safety bushing and axial fastening of the outer race, formed by two pre-assembled units (1, 1.1), each one of the pre-assembled units (1, 1.1) additionally comprising a safety bushing (8) for axial fastening of the outer race (2, 2.1) using clips (9).

The invention relates to a sealing gasket (1) providing the seal between cones in wheel bearings (7), having a cylindrical shape, made of rubber or a synthetic material, including in the median portion thereof a projection (2) intended for sealing the joint between the inner rings (6, 6.1) of an axial and radial bearing (7), preventing the entry of contaminating elements into the bearing (7), and positioned in housing recesses (9) made in the inner rings (6, 6.1) of the bearings (7), which enable effective compression of the sealing gasket (1), being vulcanised in the inner diameter of a metal core (3), configured on one side with a pushing tab (4) and on the opposite side with an anchoring tab (5).

BEARING ASSEMBLY WITH SAFETY BUSHING, AND INSERTION METHOD
The invention relates to a bearing assembly with safety bushing and to a method for inserting same into the wheel hub (not depicted) of a commercial vehicle. The assembly is formed by two pre‑assembled conical‑roller bearing units (1, 1.1), each comprising: an inner ring (2), an outer ring (3), a plurality of conical rollers (4) in a cage and a box (6) that axially retains the outer ring (2), as well as a safety bushing (8) pre-mounted on the inner ring (3) for transmitting the insertion force to the outer ring (2). In addition, one of the units (1) also includes a hermetic closure (7). After the units (1) are inserted into the wheel hub, the bushings (8) are extracted and are used as tools for inserting the respective seals (5) between the inner rings (3) and the wheel hub.
