Hydraulic rotary actuators convert hydraulic pressure into rotational motion, used for precise control in marine applications. Marine hydraulics involve fluid power systems to operate machinery like steering, winches, and cranes on ships. These systems are robust, efficient, and designed to withstand harsh marine environments.

Size: Typically ranges from 50 mm to 500 mm bore diameter.

Grade: Marine-grade hydraulic fluids (ISO VG 32, 46, or 68).

Viscosity: 15-150 cSt (dependent on operating temperature).

Buoyancy: Neutral or slightly positive buoyancy for submerged applications.

Material: Stainless steel (316L), bronze, or anodized aluminum for corrosion resistance.

Pressure Rating: 150-300 bar (standard), up to 500 bar (high-pressure models).

Rotation Angle: 90°, 180°, or continuous 360° rotation.

Operating Temperature: -20°C to +80°C (standard), -40°C to +120°C (specialized).

Seals: Nitrile (NBR), Viton (FKM), or polyurethane for marine environments.

Mounting: Foot, flange, or clevis mounting options.

IP Rating: IP66/IP67/IP69K for water and dust resistance.

Load Capacity: 500 Nm to 50,000 Nm torque output.

Yes, Hydraulic Rotary Actuators and Marine Hydraulics typically comply with maritime standards such as ISO, ABS, DNV, and Lloyd's Register, depending on the specific product and manufacturer.
