Abstract

The invention concerns a clamping device for fixing a releasable disk-shaped tool on a hand-held machine tool. Said device comprises a first element, in particular a stop nut (1), capable of being screwed on the threaded shaft, whereon is axially supported a second element provided for clamping the disk-shaped tool, in particular a clamping disk (2), an axial bearing (3) being mounted between said stop nut and said clamping disk, with friction elements for braking the second element. In order to facilitate the mounting of said clamping device and reduce production costs thereof, the axial bearing (3) comprises a housing (4) for a bearing element, a friction element (13, 14) integral in rotation with the housing (4) being in sliding contact with at least one of two said elements (1, 2).
