4. Safety Information
Always observe the following safety precautions to prevent accidents and ensure safe operation:
- Ensure all pneumatic connections are secure and leak-free before applying air pressure.
- Never exceed the maximum operating pressure specified for the cylinder.
- Wear appropriate personal protective equipment (PPE), such as safety glasses, when working with pneumatic systems.
- Depressurize the system completely before performing any maintenance or adjustments.
- Mount the cylinder securely to a stable surface to prevent movement during operation.
- Keep hands and other body parts clear of moving parts during operation.
5. Installation
Follow these steps for proper installation of your pneumatic air cylinder:
- Mounting: Securely mount the cylinder to a rigid and stable structure using appropriate fasteners. Ensure the mounting surface can withstand the forces generated by the cylinder.
- Piston Rod Connection: Attach the M16x1.5 threaded piston rod to your application's load or mechanism. Ensure the connection is aligned to prevent side loading on the rod, which can cause premature wear.
- Pneumatic Connections: Connect the air supply lines to the PT 3/8 ports. The included 8mm push-in fittings allow for quick and secure connection of 8mm outer diameter tubing. Ensure tubing is cut cleanly and inserted fully into the fittings.

6. Operation
The SC 63-200 is a double-acting cylinder, meaning air pressure is used to extend and retract the piston rod. This provides controlled movement in both directions.
- Air Supply: Connect a regulated air supply to the system. Ensure the air pressure is within the cylinder's operating range.
- Extension: To extend the piston rod, apply air pressure to the rear port (typically the port furthest from the piston rod end).
- Retraction: To retract the piston rod, apply air pressure to the front port (typically the port closest to the piston rod end) while exhausting air from the rear port.
- Speed Control: The speed of the piston rod can be adjusted using flow control valves (not included) installed in the air lines.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your air cylinder.
- Air Quality: Ensure the air supply is clean, dry, and lubricated (if required by your system design). Contaminants can damage internal seals.
- Leak Checks: Periodically check all pneumatic connections for leaks. Leaks can reduce efficiency and cause premature wear.
- Mounting Security: Verify that the cylinder remains securely mounted and that all fasteners are tight.
- Piston Rod Inspection: Inspect the piston rod for any signs of damage, scratches, or corrosion. A damaged rod can compromise seal integrity.
- Lubrication: The integrated self-lubricating bearing on the piston rod minimizes maintenance. However, if your pneumatic system uses an in-line lubricator, ensure it is properly maintained.
8. Troubleshooting
Refer to the table below for common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Cylinder not moving or slow movement | Low air pressure; Restricted airflow; Leaking connections; Damaged seals. | Check air supply and regulator; Inspect air lines and fittings for blockages or leaks; Replace seals if damaged. |
| Erratic movement | Inconsistent air pressure; Air contamination; Excessive friction. | Ensure stable air supply; Check air filter and lubricator; Inspect piston rod for damage or misalignment. |
| Air leakage from ports or seals | Loose fittings; Damaged seals; Scratched piston rod. | Tighten fittings; Replace seals; Inspect and replace piston rod if severely damaged. |
| Excessive noise | Lack of lubrication; Misalignment; Worn bearings. | Check lubrication system; Verify proper alignment of cylinder and load; Inspect bearings for wear. |
