Hydraulic cylinder for boat steering
Jastram Engineering
Jastram B Model Actuators are double-acting equal displacement
cylinders, which are directly connected to a tiller. When the B Model is
actuated it moves the tiller, which in turn moves the rudder.
The actuator sizing is primarily dependent on the maximum rudder
torque required. Once the required rudder torque is known the appropriate
actuator size can be selected.
Calculating the rudder torque is complex. An incorrect calculation can
result in failure of the steering system. Torque calculations should be
confirmed by a naval architect or designer. For more information on
actuator sizing please contact your local Jastram distributor.
Type Approved Product; see details on back page
