FIELD: mechanical engineering. SUBSTANCE: bearing has one-skirting race, balls set in ways, and cage that separates them. The one-skirting race is provided with a race member that is mounted from the side opposite to the skirt, radially projects, and is fixed to the race. A distance between the parallel planes tangentially arranged with respect to the bottom of the way on the race, which receives the race member, at the point at the axis of symmetry of the bearing and projecting portion of the inner side of the race member is 0.15-0.4 of the diameter of a ball. A distance between the plane that passes perpendicular to the longitudinal axis of the bearing and the axis of symmetry of the way bottom and the plane parallel to it that passes tangentially to the projecting portion from the side of the balls of the side of the race member is 0.3-0.7 of the diameter of a ball. EFFECT: improved design. 6 dwg
