1. A rotor bearing assembly for an underwater generator of a fluid flow power plant, the bearing assembly comprising:
a hollow cylindrical bearing carrier configured to be inserted into an interior of a rotor and releasably connected to the rotor such that they rotate together, and
an axle journal extending into an interior of the bearing carrier and rotatably supporting the bearing carrier,
wherein the axle journal and the bearing carrier are configured as a watertight installation unit configured to be at least partially inserted into the rotor interior and removable from the rotor interior while attached to the axle journal.
