Additional Description
Perfect alignment of engine and propeller shaft often tends to be a rather time consuming affair, but the Bullflex comes to the aid of the installation engineer. Even with a misalignment of 2°, the shaft will remain perfectly centered onto the flange of the reverse gearbox. On account of a special centering ring, high shaft revolutions are entirely possible and even in reverse gear, the shaft will remain perfectly centered.
