50ST20 — Pre-assembled hydraulic ram and pump assembly

The FURUNO 50ST20 assembly (reference LE-2203068) is a pre-assembled linear hydraulic ram with pump, designed for autopilot systems on sailboats. This Lecomble & Schmitt unit is a ready-to-install device, simplifying onboard installation. It is specifically suited for sailboats over 44 feet, with capacity extending up to 70 feet depending on configurations.

Performance and technical specifications

Operating on a 12V DC power supply, the FURUNO 50ST20 delivers a thrust of 700 kg and a maximum torque of 200 mkg. Its ram stroke is 300 mm, providing an amplitude of movement suitable for large sailboats. This hydraulic ram is characterized by a fixed flow rate, ensuring a consistent response from the steering system. The unit is delivered assembled and bled, including 1.20 meters of hose, with options for custom lengths.

Design and onboard integration

The design of the FURUNO 50ST20 allows for direct installation on the rudder stock or tiller quadrant, thanks to its compact format. It offers mounting flexibility, able to be fixed to the ceiling, floor, or a bulkhead. Connections are made in stainless steel for durability in a marine environment. The hydraulic ram rod is adjustable, facilitating adaptation to various boat configurations. The reversible power unit is separate, optimizing its positioning onboard and contributing to controlled energy consumption.
