The IsoFlex IFC-1619 3/4" T-Bushing is a precision-machined mounting insert designed for IsoFlex flexible shaft coupling systems. This bushing ensures proper alignment and secure mounting between gearbox output flanges and propeller shaft couplings, allowing smooth power transfer while reducing vibration and drivetrain stress.
T-bushings are essential in flexible coupling assemblies, helping maintain correct bolt alignment while absorbing shock loads and minimizing wear on connected components. This improves the longevity of couplings, shafts, and transmission systems.
The IFC-1619 is specifically designed for 3/4" (19 mm) bolt applications, commonly used in marine driveline systems and IsoFlex coupling conversions.
