Viscous Torsional Damper Brochure

Viscous torsional dampers are vital components for protection of engine and reciprocating compressor crankshafts against fatigue failures.
Lo-Rez standard or custom dampers (5″ to 50″ diameter) are normally available with thick-walled and bolted aluminum alloy housings to resist denting and provide good heat dissipation, as well as overhaul capability.
They are made in both regular (traditional) untuned as well as mechanically-tuned version.
Finned covers by Lo-Rez provide up to 50% less heat rise than plain covers, thus improving performance as well as useful TBO extension.
