FIELD: machine building.
SUBSTANCE: turbomachine roller bearing, in which shaft is installed, being formed with journal of main shaft of turbomachine high pressure stage and rotating relative to fixed foundation connected to turbomachine body. Roller bearing comprises rollers located between external race installed on the side of fixed foundation, and internal race located on the side of high pressure turbine journal. Internal race protrudes in axial direction beyond back end of high pressure turbine journal, to which it is attached with the help of pressing elements, and is equipped with facilities that prevent its slippage relative to high pressure turbine journal.
EFFECT: compactness of roller bearing, minimal weight and simple maintenance.
