Steady performance starts with controlled vibration

A viscous torsional vibration damper uses a free-rotating inertia ring and high-viscosity silicone fluid to absorb crankshaft vibration. The energy is dissipated as heat, which reduces stress on the crankshaft and supports consistent engine performance across operating conditions.

Rolled Type Viscous Damper

Rolled Type Viscous Dampers use a mechanical crimping process to seal the housing edges, creating a leak-proof assembly suited for standard engine applications. The design delivers consistent torsional vibration damping and maintains structural integrity across operating conditions. Available configurations include sheet metal fins, cast fins with bolted tone wheels, V-groove outer diameters, and integrated pulley designs. These options allow the damper to adapt to different application requirements.

Electron Beam Welded Type Viscous Damper

Electron Beam Welded Type Viscous Damper

Electron Beam Welded (EBW) dampers use high-precision welding to join the housing and cover. The process minimizes the heat-affected zone, which reduces distortion and preserves material properties. This method is suitable for joining dissimilar materials and supports consistent damping performance in high-performance applications. The compact weld bead and sealed construction contribute to durability and long-term operational stability.
