Absorber-type vibration damper, for example for a drivetrain of a motor vehicle, for damping a vibration component of a rotational movement, having the following features: at least one absorber mass which is designed to, in a manner dependent on the rotational movement, perform a vibration in order to dampen the vibration component of said rotational movement; a first guide component and a second guide component extending substantially parallel to the first guide component, between which guide components the absorber mass is movably arranged; and at least one rolling body which is designed to roll on the first and on the second guide component about an axis of rotation in order to guide the absorber mass between these; wherein the rolling body has in each case one collar to both sides of a plane which runs perpendicular to the axis of rotation and which intersects the rolling body, which collars are designed to make contact with the first and with the second guide component in order to guide the rolling body along an axis of rotation of the rotational movement; wherein a diameter of the rolling body does not increase from a value at the plane to a smaller value at its two ends along the axis of rotation; wherein the first guide component and the second guide component each comprise at least one guide raceway, and wherein the rolling body has in each case one raceway to both sides of the plane, which raceways are designed to roll on the guide raceways of the first and of the second guide component in order to guide the absorber mass between these; wherein the rolling body has in each case at least one further raceway to both sides of the plane, wherein the absorber mass furthermore has at least one guide raceway which is designed such that the further raceways of the rolling body can roll on the guide raceway of the absorber mass; or wherein the rolling body has a further raceway which intersects the plane, wherein the absorber mass furthermore has at least one guide raceway which is designed such that the further raceway of the rolling body can roll on the guide raceway of the absorber mass; and wherein the absorber mass has a recess which extends through the absorber mass along the axis of rotation of the rolling body, characterized in that the rolling body furthermore has at least one further collar to both sides of the plane, wherein the continuous recess in the absorber mass and the further collars are designed so as to guide the absorber mass along the axis of rotation. at least one absorber mass which is designed to, in a manner dependent on the rotational movement, perform a vibration in order to dampen the vibration component of said rotational movement; a first guide component and a second guide component extending substantially parallel to the first guide component, between which guide components the absorber mass is movably arranged; and at least one rolling body which is designed to roll on the first and on the second guide component about an axis of rotation in order to guide the absorber mass between these; wherein the rolling body has in each case one collar to both sides of a plane which runs perpendicular to the axis of rotation and which intersects the rolling body, which collars are designed to make contact with the first and with the second guide component in order to guide the rolling body along an axis of rotation of the rotational movement; wherein a diameter of the rolling body does not increase from a value at the plane to a smaller value at its two ends along the axis of rotation; wherein the first guide component and the second guide component each comprise at least one guide raceway, and wherein the rolling body has in each case one raceway to both sides of the plane, which raceways are designed to roll on the guide raceways of the first and of the second guide component in order to guide the absorber mass between these; wherein the rolling body has in each case at least one further raceway to both sides of the plane, wherein the absorber mass furthermore has at least one guide raceway which is designed such that the further raceways of the rolling body can roll on the guide raceway of the absorber mass; or wherein the rolling body has a further raceway which intersects the plane, wherein the absorber mass furthermore has at least one guide raceway which is designed such that the further raceway of the rolling body can roll on the guide raceway of the absorber mass; and wherein the absorber mass has a recess which extends through the absorber mass along the axis of rotation of the rolling body, characterized in that the rolling body furthermore has at least one further collar to both sides of the plane, wherein the continuous recess in the absorber mass and the further collars are designed so as to guide the absorber mass along the axis of rotation.
