Gearbox Coupling IFC-8690-95
Isoflex IFC-8690-95 flexible coupling for 8-bolt gearbox flanges: 228.6 mm bolt circle, 300 mm OD, rated 8650 Nm heavy duty / 12975 Nm medium duty.
Description
The Isoflex IFC-8690-95 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.
