Over 30 years ago, Schaeffler engineers under the LuK product brand developed a revolutionary technology for damping torsional vibrations in the drivetrain : the dual mass flywheel (DMF). Unlike a conventional flywheel, the DMF consists of two masses which are mounted to rotate against each other. A damping system in the form of arc springs is integrated into the DMF. Thus, it absorbs the torsional vibrations of the engine almost completely.

• A Luk DMF absorbs engine vibrations and torque spikes, preventing damage to the gearbox.
• A Luk dual mass flywheel (DMF) leads to less Bending Stress on the engines crankshaft.
• A Luk dual mass flywheel (DMF) leads to less vibration going to the Clutch Pedal.
• A Luk dual mass flywheel (DMF) reliably dampens torsional vibrations in the powertrain and increases driver and passenger comfort.
• A Luk dual mass flywheel dampens torsional vibrations in the powertrain and ensures driving comfort in all speed ranges. Matched to the each vehicle, the DMF enables low-speed driving and ensures lower fuel consumption and emissions.
