The 7065 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 7065 is also available in a Full Power Follow-Up version, the 7065-S.
For balanced, the 7065 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: 2,454 to 3,926 lbs. ft. (340 to 543 kg/m) / 1,718 to 2,749 lbs. ft. (238 to 380 kg/m)
Stroke: 10" to 16" (254mm to 406mm) / 10" to 16" (254mm to 406mm)
Displacement: 41 in3 to 66 in3 (672 cm3 to 1,082 cm3) / 41 in3 to 66 in3 (672 cm3 to 1,082 cm3)
For unbalanced, the 7065 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: 5,375 to 8,599 lbs. ft. (744 to 1,190 kg/m) / 3,763 to 6,021 lbs. ft. (521 to 833 kg/m)
Stroke: 10" to 16" (254mm to 406mm) / 10" to 16" (254mm to 406mm)
Displacement: 90 in3 to 144 in3 (1,475cm3 to 2,360cm3) / 90 in3 to 144 in3 (1,475cm3 to 2,360cm3)
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. Image shown is a 7085, very similar to the 7065.
