Vetus Flexible Couplings – Type Bullflex 4

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.Features:Very high flexibilitySecured against shearing off (axially and radially) ensuring safe transmission under all circumstancesMisalignment of up to 2 permissibleExcellent centring of the shaft, allowing high shaft revolutionsShaft remains centred even in reverse gearPossibility to remove the centring ring, in case two or more bearings are appliedBuilt-in thrust damper reducing axial vibrationsNon-tapered clamping hub for perfect centring and easy dismantling of the shaft assemblySpecifications:Models 1, 2 and 4 have a 4 gearbox connectionModels 8, 12 and 16 feature a 4 and 5 gearbox connectionModel 32 is provided with 6 threaded M16 holes on a pitch circle diameter of120,65 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.
