The damper consists of a primary side (blue) that is bolted to the flywheel and a secondary side (red) that is connected with the transmission input shaft. The parts can rotate against one another in bearings and are supported on two long arc springs. This results in very gentle characteristics with an extremely long wind-up angle. The springs are located in an encapsulated channel that is filled with grease and rest on hardened guide shells.'
Version with bearings for a drive shaft with universal joint is possible.
