Gearbox Coupling IFC-6700-HT
Isoflex IFC-6700-HT flexible coupling for 6-bolt gearbox flanges: 146 mm bolt circle, 195 mm OD, rated 4800 Nm heavy duty / 7000 Nm medium duty.
Description
The Isoflex IFC-6700-HT 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.
