TOW-ROW ROLLER BEARING Russian patent published in 2017 - IPC F16C19/28 F16C33/34 F16C33/58 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly to roller bearings. Two-row roller rolling bearing comprises inner split race (4), outer race (1) and rolling bodies in form of rollers (7). Inner split race (4) has cylindrical bearing races (5) on its halves and equipped with collars (8) located along bearing races (5) outer edges. Race (4) bearing races (5) are aligned by bearing assembling conditions with formation of common surface. External race (4) has two cylindrical bearing races (2), separated in race central part by common collar (3). At bearing races (2) edges on opposite sides relative to common collar (3) introduced into device collars (8) are arranged. Rollers (7) ends have spherical shape of sphere with sphere radius equal to roller (7) radius. Races (2, 5) have shape mating to rollers (7) profile.

EFFECT: increasing of permissible load in axial direction which bearing reacts to.
