Custom Pneumatic Rotary Actuator for Precision Industrial Automation Applications

Pneumatic rotary actuators convert compressed air into precise rotary motion for industrial automation systems. They are commonly used in robotic systems, automated production, packaging processes, materials handling and valve automation systems due to their reliability, repeatability and low maintenance. The choice of actuator is based on requirements such as, torque, rotation angle needed, operating pressure, mounting and environmental conditions of the application.

When combined with an electric valve actuator or an electric robot gripper, a pneumatic rotary actuator will not only provide efficiency for the machine, it will decrease downtime and increase accuracy.

Common Industrial Challenges Solved by Pneumatic Rotary Actuators

Pneumatic rotary actuators are employed by manufacturers in order to address common motion control problems that decrease production efficiencies and increase costs associated with operation.
Properly selected pneumatic rotary actuators help address such common problems as:

• Unreliable rotary positioning of parts that leads to low quality of produced items

• Slow rotary indexing and long machine cycle times

• Excessive manual part rotation during assembly

• Maintenance issues caused by malfunctioning motion components

• Downtime caused by inaccurate rotary motion

How Custom Pneumatic Rotary Actuators Improve Automation Performance

The standard actuators may fail to satisfy all the demands of the modern automation systems. Custom pneumatic rotary actuators are developed with regard to such particular factors as torque, angle of rotation, installation type, and operating environment.

With the use of custom-designed actuators, manufacturers will be able to:

• Obtain higher positioning accuracy

• Ensure consistency of cycles

• Limit equipment downtime

• Guarantee equipment reliability

• Make the integration process easier

• Optimize space usage

How to Choose the Right Pneumatic Rotary Actuator: A Step-by-Step Buyer's Guide

Step 1: Determine Your Required Torque

The torque should be determined to ensure that the load will rotate safely and efficiently. The factors that need to be taken into consideration are weight of the component, rotational speed, friction, and the presence of any additional force in the system.

Step 2: Determine the Required Rotation Angle

It is necessary to determine the angle of rotation of the component during the process. Some processes in the industry require rotation by 90° or 180°; some automation equipment is customized and requires a unique angle of rotation. Proper choice of the angle will improve the accuracy and reliability of the process.

Step 3: Ensure Compatibility of Operating Pressure and Cycle Time

You should make sure that the actuator is compatible with your compressed air and production cycle time.

Step 4: Evaluate Mounting Configuration and Available Space

Take into consideration the amount of space that is available for installing the actuator before deciding on which one to buy. Actuators can be easily installed in robotic cells, packaging equipment, and automated assembly lines.

Step 5: Assess the Operating Environment

Actuators suitable for applications involving dust, moisture, chemicals, or high-duty cycles should have been selected due to the harsh environment. This will ensure that proper sealing and durability have been provided, making the actuator maintenance-free and thus ensuring long-lasting service.

Step 6: Prepare for Future Automation Expansions

When you are considering future expansions in your manufacturing line, then go for a pneumatic rotary actuator capable of integrating well with robots and automation systems such as an electric robot gripper or electric valve actuator.

Key Features to Evaluate Before Selecting a Pneumatic Rotary Actuator

The following performance characteristics should be analyzed prior to purchasing a pneumatic rotary actuator:

• High torque output

• Accurate rotary positioning

• Adjustable rotation angles

• Compact, lightweight design

• Durable, wear-resistant construction 

• Long service life

• Ability to be integrated into industrial automation systems.

Pneumatic vs Electric Valve Actuator: Which Is Right for Your System?

Both pneumatic and electric valve actuator systems have been extensively used in the industry, but there are some differences between them which make either one more suitable to certain applications than others.

A pneumatic rotary actuator may be chosen when fast response time, simplicity of operation and robustness in a demanding production environment are important. This type of actuator is also recommended in applications where compressed air is readily available.

The electric actuator is recommended if precise positioning control is required. An electric actuator can be easily integrated into a control system and it is commonly used for automation processes that require precise valve positioning.
