FIELD: mechanical engineering.

SUBSTANCE: bearing has top and bottom races and top and bottom semi-inserts. The bottom semi-insert has at least two cross passages for batched supply of high-pressure lubricant from internal and external sources with the use of a check valve. The bearing spherical sides are spaced, which provides self-adjusting the insert with respect to the shaft. The top and bottom semi-inserts are provided with passages and spaces for major supply of lubricant in the direction of rotation of the shaft at an angle to the horizontal plane as well as additional discharging of exhaust lubricant provided in the zone close to the horizontal plane.
