Abstract

A VTG cartridge (1, 2) of an exhaust-gas turbocharger (2), with a blade bearing ring (3), and a disk (4), which is spaced apart from the blade bearing ring (3) and together with the latter delimits a hot-gas passage (5). The disk (4) is constructed from at least two layers (6, 7, 6′, 7′), which bear loosely against one another in the assembled state of the disk (4).
