Description

Flexible Vetus Bullflex 8 shaft coupling flange Ø 35 mm for propeller shaft.

Power consumption max 8,5 hp/100 rpm and kW power respectively 6,3 kW/100 rpm (DIN6270B, shaft revolutions).

Esim. Max. engine speed 3200 rpm and gear ratio 2:1 -> shaft speeds with 2:1 gear ratio is 1600 rpm and the calculated max. power rating in hp of the flex clutch: 8.5 x 1600/100 = 136 hp.

Max torque 600 Nm
Max rpm min. 2° deflection 2500 rpm
Mounting on 4" or 5" gearbox (see dimension drawing)

Mounting the drive 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
- Highly flexible
- Withstands axial and radial forces, ensuring safe transmission in all conditions
- Allows up to 2º angular deflection
- Excellent propeller shaft centering, allowing high shaft rotations
- Propeller shaft remains concentrated even in reverse
- Built-in support damper reduces axial vibration
- Wedge-free mounting centre concentrates the shaft and facilitates disassembly during maintenance
