Gearbox Coupling IFC-8400-HT
Isoflex IFC-8400-HT flexible coupling for 8-bolt gearbox flanges: 200 mm bolt circle, 275 mm OD, rated 8500 Nm heavy duty / 12750 Nm medium duty.
Description
The Isoflex IFC-8400-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.
