Installation Steps and Maintenance
Select the appropriate bore size and stroke length based on required force and travel distance.
Choose the mounting style compatible with your setup (e.g., foot mount, flange mount, or rod end).
Connect pneumatic lines with clean, dry air supply to prevent contamination.
Ensure magnetic sensor wiring is correctly installed and tested within the control system.
Adjust cushioning settings to optimize performance and minimize wear.
Regularly inspect seals, sensor connections, and piston rod for wear or damage.
Lubricate where recommended, based on operating frequency and environmental conditions.
Keep the actuator clean and free from dust or corrosive substances to extend service life.
How to Choose the Right MI Series Pneumatic Actuator
Determine required bore size and stroke length based on application load and movement range.
Verify if magnetic sensor feedback is needed for automation and control precision.
Consider environment – stainless steel models are preferred for corrosive, cleanroom, or humid applications.
Decide on mounting style according to machine integration and space constraints.
Choose between standard and adjustable cushioning based on noise and shock requirements.
Ensure compatibility with existing pneumatic and sensor control systems.
