7085 Steering Cylinder
The 7085 steering cylinder is a durable, solid cylinder that offers strength and flexibility in sizing and rudder movement for marine vessels, available in balanced and unbalanced versions. The 7085 is also available in a Full Power Follow-Up version, the 7085-S.
For balanced, the 7085 has the following torque, stroke and displacement ranges, assuming a single cylinder at 1,000 PSI (69 bar) at a 35 degree rudder angle / 45 degree rudder angle.
Torque: 4,580 to 7,400 lbs. ft. (633 to 1,023 kg/m) / 3,270 to 5,230 lbs. ft. (452 to 723 kg/m)
Stroke: 10″ to 16″ (254 mm to 406 mm)
Displacement: 79 in3 to 126 in3 (1,295 cm3 to 2,065 cm3)
For unbalanced, the 7085 has the following torque, stroke and displacement ranges, assuming two cylinders at 1,000 PSI (69 bar) at a 35 degree rudder angle / 45 degree rudder angle.
Torque: 10,800 to 16,430 lbs. ft. (1,493 to 2,272 kg/m) / 7,260 to 11,640 lbs. ft. (1,004 to 1,609 kg/m)
Stroke: 10″ to 16″ (254 mm to 406 mm)
Displacement: 174 in3 to 279 in3 (2,851 cm3 to 4,572 cm3)
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.
