MARINE PROPELLOR DRIVE SHAFT COUPLINGS

HEXAFLEX BLUELINE VIBRATION DAMPING COUPLINGS

Hexaflex BlueLine shaft couplings connect from the diesel engine gearbox to the propellor shaft in work boats, yachts, canal boats,other leisure craft and small ships.  They accept the misalignment from flexible engine mounts and reduce noise, vibration and resonance from the diesel engine.  Six sizes are available with torque ratings from 100 to 2000Nm and couplings are corrosion protected for long life.


The Hexaflex BlueLine is easy to fit with premachined dimensions to suit the gearbox output flange.  The propellor shaft hub is split for easy radial assembly and it clamps without tapers or keyways.


Long life, vibration damping and smooth running comes from the synthetic rubber flexible disc.  This is constructed to be very tough by internal loops of cord which allow flexing but achieve a long life, often ten years or more.


Typical diesel engines - Isuzu, Yanmar, Volvo Penta, Steyr Puch

Typical gearboxes - Yammar, ZF-Hurth, Technodrive, Newage PRM, Volvo
