FIELD: machine building.SUBSTANCE: invention relates to machine building, particularly to rolling bearings. Two-row roller bearing contains inner ring (5) with two cylindrical raceways (6), divided by common bead (7) in the central part of the ring, external split ring (1) with two cylindrical raceways (2) at its halves and beads (3) on their outer sides, and rolling bodies in the form of rollers (8). There are inserted device beads (4) on inner sides of cylindrical raceways (2) of external ring (1). Cylindrical raceways (6) of internal ring (5) are limited by outer frontal surfaces of bearing. Ends of rollers (8) have a spherical shape with radius equal to radius of roller (8) and raceways (2, 6) have a shape mating with the profile of rollers (8).EFFECT: increasing of permissible load in axial direction which bearing reacts to.1 cl, 1 dwg |
