FIELD: machine building.

SUBSTANCE: three-row rolling bearing comprises an inner race (1), first intermediate race (2), second intermediate race (3), outer race (4) and rolling elements (5) arranged there between. The inner (1) and the intermediate (2, 3) races are made as eccentric ones while the outer race (4) is a concentric one.
