Bullflex couplings, shaft size inch

Vetus Bullflex couplings. They are designed to ensure optimum damping of vibrations. Torsinal vibrations which are due to cycle irregularities (especially at low revs) are smoothed out extremely efficiently, owing to its very flexible rubber element. This ensures a vibration-free transmission between the engine and the propeller shaft. Bullflex coupling has an excellent alignment of centering between engine and propeller shaft. A misalignment of up to 2° between shaft and gearbox would not be a case with Bullflex. 

Bullflex couplings no 1, 2 and no. 4 have 4˝ connection for the gearbox, Models no. 8 and 16 feature both a 4˝ and a 5˝ connection. Bullflex model 32 is provided with 6 threaded M16 holes on pitch circle diameter of Ø 120.65 (4.75 inch). This enable mounting of the Bullflex couplings to most model of gearboxes, made by Hurth, Velvet, SOM, ZF, PRM.
