BALL SPHERICAL DOUBLE-ROW ROLLING BEARING Russian patent published in 2017 - IPC F16C19/18 F16C33/58 

FIELD: machine engineering.

SUBSTANCE: ball spherical double-row rolling bearing contains an outer ring (1) with two toroidal surfaces of the raceways, an inner ring (2) with a spherical surface of the raceway, a rolling element in the form of balls (3) having a profile interfaced with the toroidal surface of the raceways of the outer rings (1). Distance between the raceways of the outer ring (1) is selected in such a way that balls (3) of one raceway be in contact with balls (3) of adjacent raceways only creating clearance between balls, located on the same raceway. At least one of the ends of the inner ring (2) is equipped with a retaining ring (4), which limits the mutual skewing of the rings (1, 2).

EFFECT: elimination of the probability of the self-assembly of the bearing during its transportation or installation.
