Stern shaft shaft seal

The stern shaft seal is a critical component in marine propulsion systems, preventing seawater from entering the vessel while allowing the propeller shaft to rotate smoothly. Modern seals use advanced materials like silicon carbide and durable elastomers to withstand high pressures, abrasion, and corrosion. Lip seals, mechanical face seals, and air-based sealing systems are common designs, ensuring minimal leakage and extended service life. Proper maintenance is essential to avoid shaft wear, water ingress, and potential engine damage.
