摘要

The clamping device (1) has a clamping element, particularly a tensioning roller. The clamping element is arranged at an oscillating arm. The oscillating arm is pre-stressed against a base part (2) by a helical spring. A damper (11) is provided, which has an axial active roller bearing (12) with oblong roller bearings (14). The active roller bearing rotates around a lever arm swiveling axis (S). The roller bearings rotate around a rotating axis. The rotating axes of a part of the active roller bearing stays below a specific angle to a radial at an axial rotating axis of the roller bearing.
