Uflex USA Aluminum Inboard Cylinder with 1.25-inch Bore and 7-inch Stroke

Aluminum Inboard Cylinder - 1.25" Bore 7" Stroke

A hydraulic steering system consists of a steering pump, a cylinder tied to the rudder or the outboard or sterndrive engine, and the connecting hoses. Under normal operating conditions, a steering wheel turn will pump the oil, which flows in through the hoses to the cylinder, according to the turn direction.

With the consequent cylinder movement, the oil will flow to the pump through the hoses and, at the same time, move the engine or the helm, which are connected to the cylinder. The pumps, equipped with a valve that prevents outgoing fluid from returning along the same hose, allow the operation of the steering systems with two or more steering stations. The cylinders are double-acting and may be balanced or unbalanced. This particular cylinder is a balanced cylinder with the same number of steering wheel turns to move the helm from the center to the end stroke in two opposite directions. A well-balanced steering system needs the correct choice of pump for the cylinder.

This hydraulic cylinder for the inboard engine UC 116-I has been designed and manufactured to be used as a component in the hydraulic steering systems. The cylinder with a mobile rod is installed directly to the arm of the helm through the proper ball joint on the end part of the cylinder. On the opposite side, it is fixed directly to the boat through a support with the plate.

Features:

• Balanced (the number of turns lock-to-lock is equal to port to starboard or vice versa)

Specifications:

• Volume: 116 cc - 7 cu.in


• Torque: 58 kg (5043 lbs.)


• Output Force: 464 kg (1023 lbs)

The Uflex USA UC116-I aluminum inboard cylinder is designed for use in hydraulic steering systems on boats, offering reliable performance with a balanced design. Constructed from durable aluminum, this cylinder features a 1.25-inch bore and a 7-inch stroke, providing precise control for inboard engine steering applications. Its robust construction ensures longevity and resistance to marine environments, making it a dependable choice for boat owners seeking smooth and responsive steering.

The hydraulic system components include a steering pump, hoses, and the cylinder itself, which is directly mounted to the helm arm via a ball joint, and to the boat's structure with a support plate. When the steering wheel is turned, the pump pushes hydraulic oil through the hoses to the cylinder, causing it to extend or retract accordingly. This movement translates into steering wheel turns that adjust the boat’s direction efficiently. The UC116-I is a double-acting, balanced cylinder that maintains equal turns lock-to-lock, ensuring consistent steering response on both port and starboard directions. It is compatible with multi-station steering systems thanks to its integrated valve, which prevents fluid return along the hoses.

Designed to meet the demands of inboard steering systems, this cylinder offers an output force of approximately 1023 pounds and a torque capacity of 58 kg (around 127 lbs-ft). Its balanced design facilitates smooth operation with minimal effort, making steering more predictable and less tiring during extended use. Whether used in new installations or as replacement hardware, the UC116-I provides the performance and durability essential for safe and effective boat maneuvering. For detailed installation instructions, refer to the owner's manual available online.
