Naval propeller balancing is essential to ensure proper vessel operation, improve propulsion system efficiency, and reduce harmful vibrations. An unbalanced propeller can lead to structural issues, increased fuel consumption, and reduced lifespan of mechanical components. Therefore, relying on specialists for propeller balancing is crucial to achieving optimal performance and safety at sea.

A balanced propeller provides numerous advantages, including:

• Reduced vibrations: Decreases wear on bearings, supports, and other critical transmission components.
• Improved efficiency: A balanced propeller enhances propulsion efficiency, reducing fuel consumption.
• Lower impact on naval structures: Reduces stress and potential damage to the hull and structural elements.
• Extended component lifespan: Minimizes wear, prolonging the operational life of shafts, supports, and reducers.

To achieve precision balancing, Se.r.navi utilizes state-of-the-art instruments, including:

• Horizontal-axis electronic balancing machines: Suitable for propellers up to 3000 mm in diameter, with a maximum length of 8000 mm and a weight of up to 6000 kg.
• Vertical-axis electronic balancing machines: Ideal for smaller propellers, with a maximum diameter of 1200 mm and a weight of up to 200 kg.
• Portable vibration analyzers and systems: Enable onboard balancing without disassembly.

Professional naval propeller balancing services ensure precision and quality in compliance with international standards such as ISO 21940 and ISO 484/2. Se.r.navi employs specialized technicians capable of analyzing and correcting imbalances to maximize vessel performance.
