Description
Flexible Vetus Bullflex shaft coupling flange Ø 25 mm for propeller shaft.
Power consumption max 2,1 hp/100 rpm and kW power respectively 1,6 kW/100 rpm (DIN6270B, shaft revolutions).
Esim. Max. engine speed 3600 rpm and 2:1 gear ratio -> shaft speeds with 2.1:1 gear ratio is 1800 rpm and the calculated max. power rating in hp of the flexible clutch: 2.1 x 1800/100 = 38 hp.
- Max torque 150 Nm
- Max rpm min. 2° deflection 3250 rpm
Mounting the propeller shaft to the gearbox with a flexible coupling is an excellent vibration absorber.
Bullflex is the answer when the level of demand increases and more comfort is required for boating. It is designed to dampen vibration and hull noise. The excellent flexibility of the rubber element gives it great damping performance and ensures a quiet and vibration-free transmission between the engine and the axle box.
Bullflex Advantages
