An electric hydraulic cylinder, also known as an electro-hydraulic cylinder or electrically actuated hydraulic cylinder, is a type of cylinder that combines hydraulic power with an electric actuator to provide linear motion. It utilizes an electric motor to drive a hydraulic pump, which in turn generates hydraulic pressure to actuate the cylinder.

Here are some key features and characteristics of electric hydraulic cylinders:

Electric Actuation: Unlike traditional hydraulic cylinders that rely on fluid pressure, electric hydraulic cylinders use an electric motor to drive a hydraulic pump. The electric motor converts electrical energy into mechanical energy, which powers the hydraulic system.

Hydraulic Power: Electric hydraulic cylinders utilize hydraulic power to provide the force required for linear motion. The hydraulic pump generates hydraulic pressure, which acts on the piston inside the cylinder to produce the desired movement.

Control and Precision: Electric hydraulic cylinders offer precise control over the linear motion. They can be controlled using electrical signals, allowing for accurate positioning and speed control. This makes them suitable for applications that require precise and repeatable motion control.

Compact Design: Electric hydraulic cylinders are often designed to be compact, allowing for easy integration into various systems and equipment. They offer a combination of the compactness of electric actuators with the high force capabilities of hydraulic systems.

Force Output: The force output of an electric hydraulic cylinder is determined by the hydraulic pressure generated by the hydraulic pump and the effective piston area. They can provide high forces suitable for various applications, ranging from light-duty to heavy-duty requirements.

Energy Efficiency: Electric hydraulic cylinders can be more energy-efficient compared to purely hydraulic systems. By using an electric motor, they can optimize energy consumption, especially during idle or holding phases, by reducing or eliminating the need for continuous hydraulic fluid circulation.

Application Range: Electric hydraulic cylinders find applications in a wide range of industries and systems, including industrial automation, robotics, material handling equipment, machine tools, and more. They are used in applications that require precise and controlled linear motion, such as lifting, pressing, clamping, and positioning.

When selecting an electric hydraulic cylinder, it is important to consider factors such as the required force output, stroke length, control options, mounting options, and compatibility with the electrical and hydraulic systems. Consulting with a hydraulic system engineer or cylinder manufacturer can help in choosing the appropriate electric hydraulic cylinder for your specific application needs.
