Gearbox Coupling IFC-8900-95
Isoflex IFC-8900-95 flexible coupling for 8-bolt gearbox flanges: 300 mm bolt circle, 400 mm OD, rated 18300 Nm heavy duty / 27500 Nm medium duty.
Description
The Isoflex IFC-8900-95 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.
