FIELD: rolling-contact bearings. SUBSTANCE: bearing has inner, outer and intermediate races with thrust and radial solids of revolution. Outer and inner races have form of channel in section. Webs of channel are directed towards each other. Solids of revolution are located between webs of channels and intermediate races. Outer and inner races are sectional. During assembly of bearing, first row of thrust solids of revolution is fitted on first halves of sectional races. Intermediate races with radial solids of revolution mounted beforehand are fitted on them. Second row of thrust solids of revolution is mounted on intermediate races. Second halves of inner and outer races are mounted on thrust solids of revolution and they are secured to first halves by means of fastenings. EFFECT: high speed of rotation and enhanced reliability in axial direction. 4 cl, 1 dwg
