Rudder bearing seals in marine propulsion prevent water ingress and lubricant leakage, ensuring smooth rudder movement. They are critical for maintaining operational efficiency and protecting bearing components from corrosion. These seals are designed to withstand harsh marine environments and high loads.

Size: Typically ranges from 50 mm to 1000 mm in diameter.

Grade: Marine-grade seals compliant with ISO 9001 and ASTM standards.

Viscosity: Lubricants used have viscosities between ISO VG 68 and ISO VG 220.

Buoyancy: Neutral buoyancy to minimize drag and ensure stability.

Material: Nitrile rubber (NBR), polyurethane (PU), or fluorocarbon (FKM) for corrosion resistance.

Operating Temperature: -20°C to +80°C (-4°F to +176°F).

Pressure Rating: Up to 10 bar (145 psi) depending on design.

Watertight Integrity: IP68 or equivalent for submerged applications.

Load Capacity: Supports radial and axial loads up to 50 kN.

Compatibility: Resistant to saltwater, oils, and marine biofouling.

Rudder Bearing Seals and Marine Propulsion products typically comply with maritime standards such as ISO, ABS, DNV, and other classification society requirements.
