Investing in horsepower might not yield returns unless the propeller's pitch is optimal, ensuring maximum thrust with each turn. Bale Defence's advanced computerized propeller measuring tools allow for precise repitching, repair, and maintenance previously unachievable.
An ideally pitched propeller will:
- Significantly increase vessel speed
- Enhance fuel efficiency substantially
- Minimize vibration and related noise
- Reduce or prevent cavitation
- Prolong the lifespan of drive train and skeg bearings
- Regulate maximum R.P.M. by adjusting the pitch
Our facilities can accommodate all propellers up to 3 meters in diameter, and we can precisely determine the correct propeller dimensions for your ship's peak performance.
Additionally, our Long bed lathe can machine propeller shafts up to 7.5 meters between centers. With a swing of 1100 Diameter, we can achieve shaft trueness to .005' run-out.
