A turbo machine (1, 101), in particular turbine or compressor, includes a rotor (2, 102) which has at least one moving blade row (4, 104) with a plurality of moving blades (5, 105), and a stator (3) which has at least one guide vane row (6, 106) with a plurality of guide vanes (7, 107), at least one moving blade row (4, 104) having a shroud (8, 108). The shroud (8, 108) is designed to be self-supporting in such a way that it can at least partially absorb the centrifugal forces arising during operation and discharge them in the circumferential direction.
