Description

The Isoflex IFC-6600-95 is a flexible gearbox coupling for 6-bolt gearbox output flanges. Isoflex couplings provide a sacrificial link designed to fail before gearbox damage occurs, allow controlled engine movement to isolate vibration and help alleviate thrust-induced driveline misalignment. Designed for marine use, they are also used in industrial drivelines.
