Vetus Flexible Coupling Bullflex
€400.35 – €1,739.10
The Vetus Bullflex Coupling has been specially designed to ensure optimum damping of vibration, with excellent ease of installation. Its pre-tensioned rubber element ensures low-noise and vibration-free transmission, without backlash between the engine and the propeller shaft. Another strong point of the Bullflex coupling is the excellent alignment; even with a misalignment of 2°, the shaft will remain perfectly centered.
ADVANTAGES OF THE VETUS BULLFLEX COUPLING:
- Very high flexibility
- Optimum damping of vibrations
- Secured against shearing off (axially and radially)
- Misalignment of up to 2° permissible
- Excellent centering of the shaft, allowing for high shaft revolutions, even at 2° misalignment
- The shaft will remain centered even in reverse gear
- Possibility to remove the centering ring
- Built-in thrust damper
- Non-tapered clamping hub, for perfect centering and easy assembly/dismantling
Which Size Bullflex Coupling do I need?
The calculation is fairly simple – to determine the HP/100 r.p.m ratio figure the equation is:
(Engine HP x 100) / The maximum speed of the propeller shaft.
