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.
