FIELD: machine building.

SUBSTANCE: turbomachine rotor support contains casing, at least one its section is made symmetrically relatively to the support axis, and bearing installed on shaft, its external cage is rigidly connected with casing. At casing section or sections as least two rows of radial slots are made, creating beams between them, they are inclined relatively to longitudinal axis of the support.
