FIELD: machine building.
SUBSTANCE: radial roller bearing contains flat-bed outer race (1) with its inner surface making a cylindrical raceway, double-flange inner race (2), between boards of which is formed by cylindrical roller path, and made in the form of cylindrical rollers (3). On part of the external surface of the sides of inner race (2) there are two annular grooves to form additional race (4), where between adjacent rollers (3) is installed on separating roller (5).
EFFECT: reduced sliding friction, hence, heat release in the bearing.
