Isoflex Gearbox Coupling IFC-81710-HT (8-bolt)
Isoflex IFC-81710-HT flexible coupling for 8-bolt gearbox flanges: 184.15 mm bolt circle, 241 mm OD.
Description
The Isoflex IFC-81710-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.
