FIELD: mechanical engineering.SUBSTANCE: bearing comprises an outer (1) and an inner (2) ring with two roller paths and bearing ribs on each one, rolling elements in the form of balls (3). A distance between the conjugate points of the adjacent roller paths on each ring (1, 2) comprises 0.731-0.866 from the diameter of the ball (3). The outer ring (1) is of a split type with the roller path on each half. The bearing ribs (4) of a larger height of the outer ring (1) are arranged on the outer ends of its halves, and the bearing ribs of a smaller height (5) of the outer ring (1), designed with bevels, are arranged at the inner adjacent ends of its halves.EFFECT: increase of the operational life of the bearing, perception of an axial load in both directions is provided.1 dwg |
