Furuno 25kW 24RPM Radar Gearbox f/FR8255

The Furuno 25kW 24RPM Radar Gearbox for FR8255 is a precision transmission component engineered for maritime radar antenna drive systems operating in demanding naval and coast guard applications. This gearbox forms the mechanical backbone of Furuno's FR8255 radar platform, translating motor input into the precise rotational speed required for continuous 360-degree antenna scanning. Built for professionals who depend on reliable surface and air search capabilities in open-ocean and coastal environments, this component ensures the radar antenna maintains optimal scan rates under extended operational cycles.

Rated at 25 kilowatts output capacity with a 24 revolutions-per-minute reduction drive, the Furuno gearbox delivers the low-speed, high-torque output necessary to rotate heavy radar antennas smoothly and consistently. The RSB0070-087A gearbox incorporates sealed bearing assemblies and corrosion-resistant metallurgy to withstand salt spray, thermal cycling, and continuous duty cycles inherent to marine radar systems. At 55 pounds with compact dimensions (18 x 18 x 22 inches), the unit integrates directly into FR8255 radar pedestals without requiring structural reinforcement, though its substantial torque output demands proper motor coupling and mounting verification during installation.

Maintenance personnel and radar system technicians managing Furuno FR8255 installations—whether aboard naval vessels, commercial shipping platforms, or shore-based operations—depend on this gearbox to restore antenna rotation when original components degrade. Replacement is warranted when antenna speed drops below rated RPM, scan patterns become erratic, or bearing play develops. Direct compatibility with the FR8255 platform eliminates fitment guesswork; however, verify motor coupling alignment and bearing preload per Furuno service documentation before commissioning to ensure maximum operational life and consistent radar performance.
