5. Setup and Installation
Proper installation is crucial for the performance and longevity of your pneumatic cylinder. Follow these steps carefully:
- Mounting: Securely mount the cylinder using appropriate brackets or mounting plates (optional accessories may be required, see Figure 9). Ensure the mounting surface is stable and can support the cylinder's weight and operating forces.
- Air Line Connection: Connect pneumatic tubing to the PT 3/8 inch air ports. The cylinder includes two push-in fittings compatible with 8mm outer diameter tubing. Ensure tubing ends are cut cleanly and inserted fully into the fittings for a secure, leak-free connection.
- Piston Rod Connection: Attach the M20X1.5 threaded piston rod to your application's load. Ensure the connection is tight and properly aligned to prevent bending or excessive side loads on the rod.
- Air Supply: Connect the air supply system, including any control valves, to the cylinder's air ports.

6. Operating Instructions
The Baomain SC 80 x 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.
- Extension: Apply pressurized air to the rear port (typically marked 'A' or 'R' on control valves) to extend the piston rod. Air from the front port will exhaust.
- Retraction: Apply pressurized air to the front port (typically marked 'B' or 'P' on control valves) to retract the piston rod. Air from the rear port will exhaust.
- Cushioning Adjustment: The cushioning adjustable screws (located at each end of the cylinder) can be used to control the speed of the piston as it approaches the end of its stroke, reducing impact and noise. Turn the screw clockwise to increase cushioning and counter-clockwise to decrease it. Adjust gradually until desired performance is achieved.
Refer to Video 1 for a visual demonstration of the cylinder's operation.
7. Maintenance
The Baomain SC 80 x 200 Pneumatic Air Cylinder is designed for low maintenance. The integrated self-lubricating bearing minimizes the need for external lubrication.
- Regular Inspection: Periodically inspect the cylinder for any signs of wear, damage, or air leaks. Pay close attention to the piston rod seal and air port connections.
- Cleanliness: Keep the cylinder and surrounding area clean to prevent contaminants from entering the air system.
- Air Quality: Ensure the compressed air supply is clean, dry, and free of particulates. Use appropriate air filters and dryers in your pneumatic system.
- Tightness: Check all mounting bolts and air line connections for tightness.
8. Troubleshooting
If you encounter issues with your pneumatic air cylinder, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Cylinder does not move or moves slowly. | Insufficient air pressure; Air leak; Obstruction in air lines or cylinder; Control valve malfunction. | Check air supply pressure; Inspect for leaks and tighten connections; Clear any obstructions; Verify control valve operation. |
| Air leakage around piston rod. | Worn piston rod seal. | Replace piston rod seal (contact manufacturer for service). |
| Air leakage from ports or end caps. | Loose fittings; Damaged O-rings or seals. | Tighten fittings; Inspect and replace damaged seals. |
| Erratic or jerky movement. | Inconsistent air pressure; Excessive friction; Misalignment. | Ensure stable air supply; Check for proper lubrication; Verify cylinder alignment with load. |
