Isoflex Gearbox Coupling IFC-4900-95 (4-bolt)
Isoflex IFC-4900-95 flexible coupling for 4-bolt gearbox flanges: 120.65 mm bolt circle, 175 mm OD, rated 1200 Nm heavy duty / 1800 Nm medium duty.
Description
The Isoflex IFC-4900-95 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.
