The present invention relates to a vibration absorber (10), in particular for a drive train of a motor vehicle, comprising an internal carrier (12) which can be rotated around a rotation axis (M), a mass ring (14) which is coaxial to the internal carrier (12) and which is arranged at a radial distance from the internal carrier (12), and a plurality of spring elements (16) which connect the internal carrier (12) and the mass ring (14) to each other. The mass ring (14) has at least one radial profile formation (18) on the inner circumferential surface (15) thereof to provide sliding support in the circumferential direction and is provided with an elastomeric dampening layer (26) arranged between the internal carrier (12) and the mass ring (14), said layer being designed such that the mass ring (14) slides at least in the region of the at least one radial profile formation (18) thereof in the circumferential direction on the internal carrier (12) during a relative rotation.
