Pneumatic & Electric Actuators

Precision Motion Control & Mechanical Force Generation

Actuators function as the "muscles" of machinery, converting energy into precise motion. From simple adjustments to complex robotic systems, selecting the right energy source—pneumatic, electric, or hydraulic—is critical for operational efficiency.

Pneumatic Actuators

Utilize compressed air to exert force. These are the industry standard for clean, reliable, and cost-effective automation tasks.

Electric Actuators

Convert electrical energy into motion. Favored for high-precision linear movement and sophisticated control capabilities.

Hydraulic & Specialty

Hydraulic units handle heavy-duty tasks with high force output, while piezoelectric types offer finely tuned micro-movements.

Choosing the Right Actuator

1. Motion Requirements

Identify if your application requires Linear (straight line) or Rotary (turning) motion. This fundamental choice dictates the core mechanics of your machinery.

2. Environmental & Load

Assess external factors like dust, moisture, and temperature. Ensure the actuator's load capacity exceeds your operational demands to prevent faltering.

3. Precision & Speed

For high-speed automation, select units with high repeatability. Precise control systems ensure consistent cycles and reliable product quality.

Technical FAQ

Which is best for washdown environments?

Pneumatic actuators are preferred for washdown areas as they can be manufactured with stainless steel (SUS304/316) components and lack sensitive electronics.

How do I achieve the highest precision?

Electric linear actuators with servo or stepper motor control offer the highest level of positioning accuracy and multi-point repeatability.

Linear Actuators

Linear actuators are fundamental for applications requiring linear motion. Linear electric actuator vary widely to suit different operational demands, including single acting models (spring extend or return) which are useful where space or power is limited, and double acting cylinders which offer more control and power in both directions of movement. You might choose a single rod for typical applications or a double rod for balanced pushing and pulling actions. Non-rotating and precision non-rotating models provide stability, ensuring that the actuator applies force without twisting, crucial in tasks where alignment is key.

Guided Actuators

For applications demanding enhanced side-load stability, guided actuators are indispensable. These units are built with guide rods that help maintain alignment and resist bending and twisting forces. Options like SMC’s dual rod and heavy-duty guided actuators are perfect for restricted spaces, providing robust performance where traditional linear actuators might falter. The added stability makes them suitable for precision assembly operations and other high-stability requirements.

Grippers

  Pneumatic Grippers: Precision Handling In the realm of pick-and-place operations, pneumatic grippers are versatile tools. These devices come in various designs, such as two, three, and four-finger configurations, to handle a diverse range of materials and shapes using compressed air.

Rotary Actuators

Rotary actuators, which include rack and pinion and vane types, are tailored for tasks requiring rotational movement over fixed angles—typically 90°, 180°, and 270°. These actuators are perfect for applications where precision rotary motion is crucial, such as in automated material handling systems, assembly lines, and valve operations. Choosing the right rotary actuator involves understanding the specific degree of rotation and torque required.

Rodless Actuators

When space is at a premium, rodless actuators offer a compact solution without compromising on the travel distance of the load. These actuators use an internal piston linked to an external carriage, either magnetically or mechanically. This design not only saves space but also provides a smooth, clean operation suitable for environments where minimizing mechanical exposure is necessary.

Clamps

In manufacturing environments, pneumatic clamp cylinders are frequently employed to secure workpieces during machining or assembly processes. These clamps are valued for their durability and resistance to harsh conditions, such as weld spatter. The right clamp cylinder can significantly enhance operational reliability and production speed.

Specialty Actuators

Specialty actuators cater to unique application needs that standard actuators cannot meet. For instance, sine wave actuators are used for applications requiring exceptionally smooth acceleration and deceleration. Load-stopping and clamping models offer high precision and control, ideal for handling delicate items where traditional actuating methods might pose a risk.

Hydraulic Equipment

For the most demanding tasks, hydraulic cylinders provide the necessary force and durability. SMC offers a variety of hydraulic actuators that can handle high pressures and are available in different configurations to suit your application. These are particularly useful in industries where robustness and high force are prerequisites

Actuator Accessories

To maximize the functionality and lifespan of your actuators, a range of actuator accessories is available. Mounting brackets ensure secure installation, while piston rod clevises and alignment couplers aid in connecting and aligning actuators properly. Speed control is crucial in many applications; devices such as shock absorbers and flow controls are integral to regulating and fine-tuning the movement speed and damping, enhancing both safety and precision.
