A heavy-duty design for larger vessels. The actuators usually work in pairs. The torque figures detailed in the table below are at the standard working pressure. The pressures can be
increased to achieve a higher torque capability.
The standard AM series models are listed below. However each can be modified to suit customer requirements. If it is restricted space where the actuator needs to fit or if it is a larger actuator that is required to meet a specific rudder torque –
Wills Ridley can design the perfect cylinder to suit the customer
