Maximum working torque 36 to 448 kNm

Rolls-Royce Actuator type of steering gear provides the reliability and redundancy required for many naval applications by using two actuator systems to provide single rudder operation. With one actuator bypassed, 50 per cent of the torque is still available.

A design feature provides fewer interface surfaces with the ship, as the anchor brackets can be welded directly onto the hull cartridge, making installation less tolerance critical.

A seven-model range is available for torques from 3.5 to 50 tonne/metres.
