- Excellent centring of the shaft, allowing high shaft revolutions.
- Shaft remains centred even in reverse gear.
- Possibility to remove the centring ring, in case two or more bearings are applied.
- Built-in thrust damper reducing axial vibrations.
- Non-tapered clamping hub for perfect centring and easy dismantling of the shaft assembly.
- Models 1, 2 and 4 have a 4” gearbox connection.
- Models 8, 12 and 16 feature a 4” and 5” gearbox connection.
- Model 32 is provided with 6 threaded M16 holes on a pitch circle diameter of Ø 120,65 mm / 4,75” enabling mounting of the couplings to most models of gearboxes (Hurth, Velvet, TD, ZF and P.R.M.)
- VETUS can also supply the required fastenings for installation of the Bullflex onto the gearbox. This coupling is not suitable for V-Drives.

The Bullflex is the answer to the increasing demand of greater boating comfort. It is especially designed to ensure optimum damping of vibrations.
Torsional vibrations are smoothed out extremely efficiently by its very flexible rubber element, ensuring low-noise and vibration-free transmission without backlash between the engine and propeller shaft.
Another strong characteristic is the excellent alignment of the propeller shaft.
