FIELD: mechanical engineering. SUBSTANCE: bearing has inner and outer races with ways and rolling bodies, which is interposed between them and set in a separator. The bearing has two additional thrust races with ways. One of the races is coupled with the outer race and the other with the inner race. The separator is interposed between the first thrust race and the outer race and the second thrust race and the inner race. Each thrust race is made in block of the radial race and made as triangle with ways arranged from the side of the hypotenuse. There are at least one groove in the races from the side of balls. A member of the separator is received in the groove. The bearing has also fastening races. Passages, which are filled with lubricant, are made in the members of the separator. The bearing can be provided with a spring interposed between the face of the separator member and groove bottom. EFFECT: enhanced reliability. 3 cl, 1 dwg
