What is a Pneumatic Linear Actuator？
Linear pneumatic actuators are actuators that use compressed air to generate linear motion, providing efficient, reliable and safe solutions for different application scenarios.
How it works:
- Compressed air enters the cylinder: it pushes the piston to move, driving the telescopic rod to extend or retract, thereby achieving linear motion.
- Compressed air leaves the cylinder: the piston moves back and the telescopic rod retracts.
In simple terms, it is like a "push-pull rod" driven by compressed air.
What are the 4 Types of Linear Actuators?
1. Pneumatic Linear Actuators
Pneumatic linear actuators use compressed air to move a piston within a cylinder, creating linear motion.
Pneumatic actuator valve commonly found in industrial applications, they provide reliable, fast actuation for machinery and equipment.Pneumatic actuators are easy to install and maintain, making them an affordable choice for many automation tasks.
2. Hydraulic Actuators
Hydraulic actuators use pressurized fluid (usually oil) to produce linear motion.
Commonly used in applications requiring high forces, such as construction, agricultural equipment, and heavy machinery.
Withstands harsh environmental conditions but has more complex maintenance requirements.
3. Mechanical or Electromechanical Linear Actuators
Mechanical linear actuators use a rotating screw mechanism, which is converted into linear motion.
Mechanical linear actuators are precise and have high positional accuracy, making them suitable for applications requiring fine control and adjustability.
Common uses include in automotive and robotics industries.
4. Electric Linear Actuators
They use an electric motor to drive either a leadscrew or rack and pinion system, converting rotational motion into linear motion.
Electric linear actuators, widely used in medical, home, and HVAC applications, offer quiet and efficient actuation, flexibility, and easy control in a compact design.
