Isoflex Gearbox Coupling IFC-81610-HT (8-bolt)
Isoflex IFC-81610-HT flexible coupling for 8-bolt gearbox flanges: 155.6 mm bolt circle, 220 mm OD, rated 3700 Nm heavy duty / 5500 Nm medium duty.
Description
The Isoflex IFC-81610-HT is a flexible gearbox coupling for 8-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.
