Furuno RSB134-112 6Kw Gearbox For DRS6AX Open Array System

The Furuno RSB134-112 6Kw Gearbox for DRS6AX Open Array System is a critical power-transmission component designed for commercial and professional marine radar installations. This pedestal-mounted gearbox serves as the mechanical interface between the antenna drive motor and the rotating antenna assembly, enabling smooth 360-degree scanning at controlled rotational speeds. Built to Furuno's exacting standards, it's engineered for continuous maritime duty where reliability and performance directly impact vessel safety and target detection capability.

The RSB134-112 gearbox is rated for 6-kilowatt input power and provides the mechanical gear reduction necessary to deliver optimal torque and rotational velocity to the DRS6AX antenna array. The unit weighs 35 pounds and is engineered with heavy-duty gearing and sealed bearings to withstand salt-spray corrosion, vibration from vessel motion, and the thermal cycling common in open-ocean environments. Its pedestal mounting design allows for secure, vibration-damped installation while maintaining precise antenna alignment critical to radar imaging quality and bearing accuracy.

Maritime operators running Furuno DRS6AX open-array radar systems—including fishing vessels, cargo ships, tankers, and coast guard platforms—rely on this gearbox to maintain continuous, uninterrupted antenna rotation during watch cycles. Installation integrates directly into the DRS6AX pedestal assembly and pairs with Furuno's antenna drive motor; replacement or upgrade typically requires professional marine electronics technicians to ensure proper motor coupling, alignment, and electrical integration with the radar control unit.
