The 7097D steering cylinder is a durable, solid cylinder that offers strength and flexibility in sizing and rudder movement for marine vessels. Made for larger rudder sizes and twin tiller arms, the 7097D is only available in an unbalanced version.
For unbalanced, the 7097D has the following torque, stroke and displacement ranges, assuming two cylinders at 2,000 PSI (138 bar) at a 35 degree rudder angle / 45 degree rudder angle.
Torque: 192,365 to 384,729 lbs. ft. (26,596 to 53,192 kg/m) / 134,695 to 269,391 lbs. ft. (18,623 to 37,246 kg/m)
Stroke: 24″ to 48″ (610 mm to 1,219 mm) / 24″ to 48″ (610 mm to 1,219 mm)
Displacement: 1,616 in3 to 3,232 in3 (26,481cm3 to 52,962cm3) / 1,616 in3 to 3,232 in3 (26,481cm3 to 52,962cm3)
Kobelt requires a steering gear torque or rudder calculation be done before sizing or ordering any steering system, to ensure the correct mix of pressure, displacement, stroke, parts and torque. Contact Kobelt or your local Kobelt partner to review this information. Photo shown is the 7094, similar to the 7097D.
