We have customers from a wide range of industries. And we love the variety of solutions we’re able to provide. It’s just one of the reasons we love what we do so much. While they all serve their customers in different ways with different products, one thing is consistent across all operations; the requirement to automate repetitive processes. Today, we’re taking a look at how one particular component plays a role in almost every manufacturing workflow, prompting the question for you: What else can we automate to increase throughput, reduce manual fatigue or even minimise error?
Enter stage right... Linear Actuators
Linear actuators are essential components in modern manufacturing due to their ability to provide controlled linear motion in automated systems.
There are three main types of linear actuators: pneumatic, hydraulic, and electric. Pneumatic actuators use compressed air to move a piston inside a cylinder (usually controlled by a MAC Valve), creating linear motion. They’re commonly used in industrial automation because they’re quick to respond, relatively simple in design, and well-suited to repetitive tasks. Hydraulic actuators operate similarly but use pressurised fluid, making them better suited to heavy loads where high force is required. Electric actuators rely on a motor and lead screw to convert rotary motion into linear movement and are often chosen for applications that need precise control. The choice between types usually depends on factors like speed, force, environment, and level of control required.
Here are ten key applications of linear actuators in a manufacturing setting:

1. Automated Assembly Lines
Linear actuators play a crucial role in automating repetitive tasks on assembly lines. They move parts between stations, align components, or operate tools like presses and screwdrivers. This not only boosts production speed but also improves accuracy and consistency.
2. Material Handling
In material handling systems, actuators are used to lift, position, and transfer products between conveyors or storage units. Their ability to manage loads with precision reduces product damage and enhances workflow efficiency.
3. Packaging Systems
Linear actuators are commonly used in packaging machinery for tasks such as carton folding, sealing, labelling, and sorting. Their repeatable motion ensures packaging is uniform and securely completed, meeting quality control standards.
4. Welding Operations
In robotic welding setups, actuators position the welding tool or the workpiece itself. Their high degree of accuracy is vital to producing clean, strong welds, especially in automated TIG or MIG welding applications.
5. Inspection Systems
Vision or sensor-based inspection systems often rely on actuators to precisely move products into view. This movement allows for detailed quality checks without interrupting the production flow, helping identify defects in real time.
6. Adjustable Workstations
Actuators can be used to create ergonomic, height-adjustable workbenches or tool holders. These customizable stations enhance worker comfort and safety, reducing the risk of injury and fatigue in repetitive tasks.
7. Machining and Tool Positioning
Precision machining requires tools and parts to be positioned with micron-level accuracy. Linear actuators help control cutting depth, tool engagement, and part alignment to meet exacting manufacturing tolerances.
8. Clamping and Holding
Actuators can be integrated into clamping systems to securely hold materials during processes like drilling, milling, or laser cutting. This ensures stability and improves overall machining accuracy.
9. 3D Printing and Additive Manufacturing
In 3D printing setups, actuators are used to move the print head or platform in the X, Y, and Z axes. Their smooth motion is essential for accurate layer deposition, which affects the quality and integrity of printed parts.
10. Robotic Systems Integration
Linear actuators are often embedded within robotic arms and platforms. They assist in extending reach, adjusting gripper positions, or changing tool orientations. This versatility makes robots more adaptable to various manufacturing tasks.
The Role of Linear Actuators in Smarter Manufacturing
Linear actuators offer immense value in manufacturing by enhancing automation, accuracy, and efficiency. Their wide range of applications—from assembly and welding to inspection and robotics—makes them indispensable in modern production environments. As manufacturing continues to evolve toward greater automation and smart factory systems, the demand for precise, reliable linear motion will only grow, cementing the actuator’s role as a foundational element in industrial engineering.
