Abstract: A roller bearing includes a plurality of conical roller bodies arranged between inner and outer rings, and a cage having an annular sectional body mounted between the inner and outer rings. The annular sectional body further having an annular oil thrower located on each transverse side, each oil thrower having internal and external radial projections, wherein the free end of each projection is positioned opposite and away from a corresponding one of the inner and outer rings. The bearing has functional axial and radial clearances between the internal and external radial projections and the internal and outer rings. The clearances facilitate the passage of a bearing lubrication fluid there through and form an obstacle to the passage of solid particles.

Abstract: An assembly forming a bearing housing is equipped with an information sensing system comprising a coder generating magnetic pulses and a sensor provided with at least two sensitive elements able to detect these pulses. The bearing has a rotating internal member, a fixed external member and rolling bodies disposed in a bearing space. The bearing housing also has a cover secured to the fixed member in order to obstruct the bearing space laterally. The coder is secured to the rotating member behind the cover and the sensitive elements being disposed opposite the coder, in front of the cover, so that the pulses are detected through the cover. The sensor has a device for processing the signals detected by the sensitive elements. The device comprises a triggering device and a device for applying the XOR function to the signals triggered, so as to increase the resolution of the output signal with respect to that of the signals detected.

Abstract: The invention relates to a roller bearing with conical roller bodies (4), arranged between inner (1) and outer rings (2) and a cage with an annular sectional body (5) and an annular deflector body (10) for the body (5) to each transverse side, each deflector (10) comprising internal (11) and external (12) radial projections, the free end of each projection (11, 12) bering arranged opposing and at a separation from the corresponding ring (1, 2) such that the bearing has functional axial and radial play (13) between the projections (11, 12) and the rings (1, 2), Said play is such as to permit the passage of a bearing librication fluid and to form an obstacle to the passage of solid particules. The invention further relates to a cage for assembly in such a roller bearing.
