MG5050

The Twin Disc MG5050 is a marine propulsion gearbox delivering up to 5,050 kW with a single‑stage 2.5:1 reduction, converting a 1800 rpm engine output to roughly 720 rpm propeller speed. As a Reduction Gear, it is normally installed between a propulsion engine or motor and the shaft line, reducing or adapting rotational speed and transmitting torque to the propeller. In that role, its primary purpose is to match prime-mover speed and torque to the propulsion shaft while providing the required clutching or reduction arrangement. Single-stage, multi-stage and epicyclic marine gearboxes differ in gear geometry and layout, but all depend on alignment, tooth contact, bearings and clean pressurized lubrication. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
