JASTRAM Compact SG-500 compact steering gear for smaller vessels. As a Steering Gear, it is normally installed in the steering-gear compartment at the aft end of the vessel, mechanically connected to the rudder stock or steering actuator. In that role, its primary purpose is to move and hold the rudder in response to bridge steering commands. Steering-gear designs differ in actuator arrangement, but all depend on hydraulic power, mechanical linkage, feedback and emergency changeover functions. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
