BALL CAGELESS BEARING Russian patent published in 2015 - IPC F16C19/18 F16C33/58 

FIELD: machine building.

SUBSTANCE: bearing contains rolling bodies in form of balls (3), an outer race (1) with a raceway, and an internal race (2) with two toroidal raceways conjugate with ball (3) surfaces. The distance between the raceways is selected such that balls (3) of one raceway be in contact only with balls (3) of adjacent raceways creating clearance between balls (3) on the same raceway. The raceway of the outer race (1) is designed as spherical and conjugate with the surfaces of balls (3).

EFFECT: providing a mutual distortion of internal and outer races of the bearing that significantly improves its operational characteristics.
