VETUS Bullflex 8 Transmission Shaft Centering Ring

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. Features: - 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.
