Rotary Vibration Damper
Detroit Diesel

The rotary vibration damper is a crucial component designed to mitigate torsional vibrations within the engine’s crankshaft assembly. Its cast iron case provides a sturdy, resilient enclosure that absorbs and dampens the oscillations generated during engine operation, thereby reducing stress on connected components. With an outer diameter of 360 mm and a width of 88 mm, it fits precisely into the engine’s harmonic balancing system, ensuring smooth engine running and longevity. The six bolt holes, each threaded M8 mm, facilitate secure attachment, maintaining alignment under high torque conditions. By controlling torsional vibrations, this damper helps prevent premature wear, fatigue, and potential failure of the crankshaft and other drivetrain parts. This enhances engine reliability, reduces maintenance costs, and contributes to quieter operation.
