Gearbox Coupling IFC-4600-95
Isoflex IFC-4600-95 flexible coupling for 4-bolt gearbox flanges: 80 mm bolt circle, 125 mm OD, rated 375 Nm heavy duty / 560 Nm medium duty.
Description
The Isoflex IFC-4600-95 is a flexible gearbox coupling for 4-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.
