A mass damper system has a damper mass carrier and a damper mass movably received at the damper mass carrier a lubricant supply, a lubricant collector, and a lubricant distributor radially offset to one another with the damper mass carrier, the lubricant supply arranged at a shorter radial distance from a central axis than the lubricant collector, and the lubricant distributor arranged at a greater radial distance from the central axis than the lubricant collector to collect lubricant supplied by the lubricant supply and to guide the lubricant through the lubricant distributor to the damper mass. A stop arrangement limits a deflection path of the damper mass relative to the damper mass carrier, and the lubricant distributor has a lubricant feed that leads from the lubricant collector to a constructional unit requiring intensive lubrication.
