B&G Hydraulic Ram T2 24V Drive Unit – Marine Hydraulic Linear Actuator for Vessel Steering

The B&G Hydraulic Ram T2 24V Drive Unit is a robust and reliable hydraulic linear actuator designed specifically for marine vessel steering systems. This pre-filled, sealed unit integrates a cylinder, pump, motor, clutch, and reservoir, providing a compact solution for vessels with mechanical primary steering that can be back-driven. When the clutch is disengaged, the unit’s cylinder freely moves with the primary steering, allowing seamless operation in both manual and autopilot modes. To activate autopilot functions, the course computer energizes the clutch solenoid coil and operates the bi-directional motor to extend or retract the ram, ensuring precise control of the vessel's rudder. Internal relief valves safeguard the unit from rudder strikes and grounding incidents, enhancing durability and safety in demanding marine environments. The RAM-T2-24V is engineered to withstand a maximum thrust of 675 kg during intermittent operation, with a hard-over time of approximately 9 seconds, making it suitable for a variety of vessel sizes and steering requirements. The hydraulic ram is rated for operation within a temperature range from -20°C to +65°C, ensuring reliable performance across diverse climate conditions. The relief valve is set at 62 bar to prevent overpressure, and the unit offers back-drive capability at 7 kg during a 12-second hard-over scenario, providing responsive rudder control. Compatibility with control systems like H5000 and NAC3 makes integration straightforward for modern yacht and vessel automation systems. The motor operates at 24V DC with a power draw of 100 watts and a maximum current of 11.2 amps at 12V, with reversing rotation for flexible control. The unit features IP44 protection, suitable for marine environments, and includes a 1-meter, 2-core flying lead connection for easy wiring. Constructed with durable materials such as aluminum body, chrome-plated stainless steel piston rod, and nitrile and PTFE seals, the B&G Hydraulic Ram T2 24V ensures longevity and resistance to corrosion and wear. This hydraulic drive unit is critical for maintaining precise steering control, especially in applications requiring reliable autopilot functionality and robust mechanical protection.
