Comprehensive Guide to Linear Actuators

In modern automation and smart devices, linear actuators play a vital role. They convert energy into precise linear motion, driving a wide range of applications from industrial machinery to smart home devices. Whether electric, pneumatic, or hydraulic, choosing the right actuator not only affects equipment performance but also determines system reliability and efficiency. This guide will give you a comprehensive understanding of the types of linear actuators, key technical parameters, application scenarios, and selection tips, helping you make informed decisions and achieve optimal application results.

1. What is a Linear Actuator?

Simply put, a Linear Actuator is an electromechanical device that converts energy into linear mechanical motion. Its core function is to transform input energy—whether Electric Power, Hydraulic Pressure, or Pneumatic Pressure—into controllable linear pushing, pulling, or positioning actions (Linear Motion / Positioning), thereby driving mechanical systems to perform tasks as intended.

Unlike Rotary Motion, linear motion occurs along a straight path, making it easier to achieve High Precision Control (Precision Control) and Accurate Positioning. Therefore, in Industrial Automation, Precision Machinery, and Smart Systems, linear actuators are widely used. For example, robotic arms (Robotic Arm) on production lines can use linear actuators to perform gripping, handling, or assembly operations; in pipeline systems, actuators can control Electric Valves to regulate fluid flow; in Home Automation, they are applied in Automatic Doors, Height-Adjustable Desks, or Motorized Curtains, enabling convenient automated control.

In addition, linear actuators can not only perform single push-pull actions but also achieve Continuous Precision Positioning. Combined with Position Sensors / Feedback Sensors and a Control System, actuators can adjust movements based on real-time feedback to achieve Closed-Loop Control, ensuring smooth, reliable, and repeatable mechanical actions.

In summary, a linear actuator is a key electromechanical device that efficiently converts energy into Controllable, Accurate, Repeatable Linear Motion, making it an indispensable core component in modern industrial automation, robotic systems, and smart devices.

2. Working Principle of Linear Actuators

In industrial automation and mechanical equipment, the principle of linear actuators is fundamental knowledge. A linear actuator is a device that converts energy into controllable mechanical motion, allowing equipment to push, pull, or precisely position. Different types of actuators have different input methods and operating characteristics.

There are three main types of linear actuators:

Electric Linear Actuators: 

Take current or voltage as input, use a motor to drive a screw, gear, or other transmission mechanism to achieve linear motion. They are suitable for scenarios requiring precise displacement control, such as automated production lines or precision machinery.

Hydraulic Actuators: 

Use incompressible liquid pressure to convert fluid energy into mechanical force, providing high thrust. They are commonly used in industrial machinery, heavy-duty equipment, and construction machinery. Their advantages include smooth, powerful motion and high load capacity.

Pneumatic Actuators: 

Feature fast response. They achieve motion by using compressed air to push pistons or rods, suitable for lightweight, high-speed operations such as automated assembly, sorting machines, or packaging equipment.

After understanding the basic types and operating characteristics of electric, hydraulic, and pneumatic linear actuators, we need to look deeper into how they work. Regardless of type, actuators always consist of several core components: Power Supply, Actuator Body, Mechanical Load, and Controller. These components work together to convert input energy effectively and precisely into mechanical action.

Power Supply:

The power supply provides energy to drive the actuator. In electric actuators, the motor is the core for achieving mechanical motion. The power supply delivers electricity to the motor, whose rotation drives the screw, gear, or transmission mechanism, precisely converting electrical energy into linear motion. This process determines the actuator’s thrust, speed, and positioning accuracy, and is key to smooth system operation. Inverters or controllers further regulate motor input, making movement more stable and reliable. Although hydraulic actuators rely on hydraulic pumps and pneumatic actuators rely on compressed air, the motor’s role in electric actuators is the most prominent. A stable and reliable power supply and a high-efficiency motor are fundamental to ensuring fast response and precise motion, directly affecting performance and lifespan.

Actuator Body:

The actuator body is the core part where energy is converted into linear motion. It usually contains pistons, screws, gears, or other transmission mechanisms, which determine output accuracy, speed, and load capacity. The design of the actuator body directly affects motion stability and efficiency.

Mechanical Load:
The mechanical load is the target device driven by the actuator, such as doors, valves, slides, or robotic arms. The weight and resistance of the load determine the required thrust and speed of the actuator, as well as the overall stability and service life of the system.

Controller:
The controller regulates input signals so the actuator operates at preset speed, position, and force. In closed-loop systems, the controller also adjusts actions based on sensor feedback in real time, ensuring precise and stable linear motion while preventing overload or impact.

3. Types of Linear Actuators

Linear actuators can be divided into three main categories based on driving energy and working principles: Electric Linear Actuator, Hydraulic Linear Actuator, and Pneumatic Linear Actuator. Each has unique features, applications, and internal structures.

1.Electric Linear Actuator

An electric actuator uses a Motor to drive screws, gears, or belts, precisely converting electrical energy into linear motion. It offers high precision, easy control, and simple maintenance.

Electric linear actuators can be further divided into:

Lead Screw / Ball Screw Actuator: 

Moves linearly through a screw and nut, suitable for medium-small loads and high-precision applications.

Rack and Pinion Actuator: 

Converts motion through gear-rack engagement, suitable for long-stroke, heavy-load applications.

Belt-Driven Actuator:

Uses synchronous belt transmission for fast, long-stroke linear movement, often applied in lightweight automation equipment.

2.Hydraulic Linear Actuator

A hydraulic actuator uses a Hydraulic Pump and liquid pressure to drive a piston, achieving high-thrust linear motion. It is suitable for heavy loads and continuous operation.

Hydraulic actuators can be further classified as:

Tie-Rod Cylinder / Welded Cylinder: 

Sturdy structure, suitable for high-pressure, heavy-load industrial applications.

Piston Rod Cylinder:

The most common type, transferring thrust through a piston rod, customizable in stroke and diameter.

Adjustable Stroke Cylinder:

Allows adjustment of maximum stroke as required, adapting flexibly to different working environments.

Locking Cylinder: 

With mechanical locking, used for load holding or safety protection.

3.Pneumatic Linear Actuator

A pneumatic actuator uses Compressed Air to push pistons or rods, enabling fast, reciprocating linear motion. To highlight application characteristics, pneumatic actuators can be classified by structure and motion:

Rodless Cylinder:

The piston drives the load directly through magnetic force or a slider, suitable for long-stroke, space-constrained scenarios.

Guided Cylinder / Guided Rod Cylinder: 

With guide rods or sliders to ensure smooth motion, suitable for applications with large lateral forces.

Compact Cylinder / Mini Cylinder: 

Small and lightweight, suitable for light-load, space-limited automation equipment.

4.Advantages of Electric Linear Actuators

In modern Industrial Automation, Robotics Systems, and Smart Devices, Electric Linear Actuators are gradually replacing traditional Hydraulic Actuators and Pneumatic Actuators due to their multiple advantages.

High Precision and Repeatability

Electric actuators, driven by servo motors or stepper motors, utilize lead screws / ball screws or rack-and-pinion mechanisms. Combined with position sensors and closed-loop control, they can achieve micron-level positioning accuracy and repeatability, making them ideal for precision assembly, semiconductor manufacturing, and high-accuracy measurement equipment. In contrast, hydraulic and pneumatic systems are limited in positioning accuracy and repeatability due to the compressibility of fluids or gases and pipeline delays.

Programmable and Intelligent Control

Electric actuators are easy to integrate with PLCs, DCS, or Industrial Ethernet, enabling software-based control of stroke, velocity, acceleration, and torque. Users can quickly adjust motion parameters to achieve complex motion profiles and intelligent operation. By comparison, hydraulic or pneumatic actuators typically rely on mechanical valve adjustments or proportional valves, which offer limited flexibility and response precision.

High Energy Efficiency and Low Maintenance

Electric actuators directly convert electrical energy into mechanical energy with efficiencies of over 80%. They require neither hydraulic oil nor compressed air, resulting in lower energy consumption and simpler maintenance. Hydraulic systems depend on pumps, pipelines, and hydraulic fluids, which introduce energy losses and leakage risks. Pneumatic systems are limited by the low efficiency of compressed air and lead to higher long-term operating costs. In contrast, electric systems are not only energy-saving but also reduce maintenance frequency and downtime costs.

Environmental Adaptability

Electric actuators eliminate the risks of hydraulic oil leakage or gas leakage, making them suitable for environments with strict cleanliness requirements such as cleanrooms, medical devices, and food processing. Furthermore, with proper IP-rated protection, actuators can withstand humid, dusty, or corrosive environments, ensuring long-term stable operation.

Dynamic Response and Controllable Force

With the support of high-performance motors and motor drivers/servo drives, electric actuators deliver high dynamic response, precise force/thrust control, and customizable velocity profiles. This makes them well-suited for high-frequency reciprocation, precision positioning, and complex trajectory movements. In contrast, hydraulic and pneumatic systems are constrained by inertia and fluid compressibility, which limit their response speed and force control capabilities.

5. How to Choose the Right Linear Actuator

Selecting the right Linear Actuator is essential to ensure the efficient and reliable operation of a mechanical system. Different types of actuators vary significantly in thrust, stroke, speed, accuracy, and control methods, so multiple factors need to be considered during the selection process.

Thrust and Load Capacity

The first step is to define the mechanical load and the required thrust. Electric Linear Actuators, powered by servo motors or stepper motors, can deliver precise thrust, making them suitable for medium-to-light loads and high-precision positioning. Hydraulic Linear Actuators can provide very high thrust, making them ideal for heavy loads and continuous-duty applications. Pneumatic Linear Actuators are best suited for lightweight loads and fast reciprocating motion.

When selecting, the actuator’s maximum thrust should be higher than the required load capacity, with an additional 20–30% safety margin to ensure long-term stability. For applications requiring higher thrust or heavy-load handling—such as medical bed adjustment, heavy industrial equipment, or high-load automation systems—a high-thrust electric actuator like Jiecang JC35B8 is a suitable choice. It can deliver up to 6,000N of powerful thrust while maintaining a compact design and high protection rating, ensuring stable performance even in demanding environments.

Stroke and Velocity

The stroke length of an actuator determines the maximum travel range of the load. Electric actuators are well-suited for precise positioning, though their speed may be limited over longer strokes. Hydraulic and pneumatic actuators, on the other hand, can achieve high-speed, long-stroke movements, making them suitable for production line handling or automated assembly. Speed requirements should be evaluated based on the application: high-frequency reciprocating operations demand fast dynamic response, while precision assembly or positioning tasks emphasize stability and smoothness.

Precision and Repeatability

Applications requiring high accuracy place strict demands on positioning precision. Electric actuators, equipped with closed-loop control and position sensors, can achieve micron-level accuracy and excellent repeatability, making them ideal for robotic arms, semiconductor equipment, or laboratory platforms. In contrast, hydraulic and pneumatic actuators are inherently limited in positioning precision and repeatability due to the compressibility of fluids and gases.

In such high-precision environments, the Jiecang JC35W5 demonstrates significant advantages. It features a built-in electronic limit switch and an optional dual Hall sensor feedback system, ensuring precise positioning and repeatable operation during push rod extension and retraction. These capabilities make the JC35W5 an outstanding choice for applications that demand precise control, such as medical bed adjustment, smart furniture lifting systems, and precision handling in industrial automation.

Control Method

The choice of control method should align with the requirements of the automation system. Electric actuators can be easily integrated with PLCs (Programmable Logic Controllers), DCS (Distributed Control Systems), or Industrial Ethernet, enabling fully programmable control of stroke, speed, acceleration, and torque. By contrast, hydraulic and pneumatic actuators usually rely on proportional valves or mechanical adjustment devices, offering relatively lower flexibility.

Operating Environment and IP Rating

Environmental conditions have a direct impact on actuator lifespan. Electric actuators can be designed with different IP ratings, making them suitable for humid, dusty, or corrosive environments. Hydraulic systems must prevent oil leakage, while pneumatic systems depend on clean, stable air supply. For extreme conditions—such as high temperatures, humidity, or vibration—actuators with enhanced environmental resistance should be prioritized.

Energy Efficiency and Maintenance

Electric actuators convert electrical energy directly into mechanical energy, achieving high efficiency (>80%) with low maintenance requirements. Hydraulic systems require regular oil replacement and pump station monitoring, while pneumatic systems suffer from energy losses due to air leaks, leading to higher overall consumption. Depending on equipment usage frequency and maintenance capacity, selecting an energy-efficient and stable solution is essential.

Cost and ROI

Beyond performance, economic factors must be considered, including initial investment, installation costs, and long-term operating expenses. While electric actuators typically have a higher upfront cost, their high efficiency and low maintenance result in reduced operating costs over time. In contrast, hydraulic and pneumatic systems may offer lower initial costs but entail higher long-term expenses due to energy consumption and maintenance. Calculating return on investment (ROI) helps determine the most cost-effective solution.

Solar Powered

Solar-powered systems often operate with limited voltage and current, so actuators must deliver high energy efficiency and maintain thrust output and precise positioning under low-power conditions. This makes electric linear actuators far more suitable than hydraulic or pneumatic systems, as hydraulics require pump stations and pneumatics depend on compressed air—both impractical for standalone solar systems.

Against this backdrop, the Jiecang JC35SA16 was developed. Specifically designed for solar applications, this high-performance electric linear actuator combines high load capacity with outstanding weather resistance. It is widely used in photovoltaic tracking systems, smart shading devices, and other automation scenarios requiring high IP protection and precise motion control.
