Gearbox Coupling IFC-6300-95

Isoflex IFC-6300-95 flexible coupling for 6-bolt gearbox flanges: 152.4 mm bolt circle, 212 mm OD, rated 3600 Nm heavy duty / 5400 Nm medium duty.

Description

The Isoflex IFC-6300-95 is a flexible gearbox coupling for 6-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.
