About the Airtac SC80 Standard Cylinder SC80X18
The AirTAC SC80X18 is a compact-stroke double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, ideal for short, high-force clamping or ejecting tasks. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth end-of-stroke deceleration even in rapid cycling.
With a body length of just 182 mm plus the 18 mm stroke, this tie-rod cylinder fits into tight machine envelopes where a full ISO 15552 profile would be too long. The PT3/8 ports and M20x1.5 rod thread ensure straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X18 Is Used
Short-Stroke Clamping
The 18 mm stroke and 2513 N force at 0.5 MPa make this cylinder perfect for fixture clamps and press jigs where travel is minimal but holding force must be high.
Part Ejection
Use the SC80X18 to eject parts from moulds or stamping dies. The adjustable cushion protects the tooling by softening the impact at the end of the short, rapid stroke.
Diverter Gates
Ideal for actuating small diverter gates on conveyor lines. The compact 200 mm total extended length fits easily beside narrow belt sections.
Is the Airtac SC80 Standard Cylinder SC80X18 the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore provides 3927 N at 0.5 MPa. If a shorter body is required, the SC63 bore offers 1559 N. Ensure the 18 mm stroke matches your exact travel requirement—non-standard strokes are available on request.
When replacing an existing cylinder, match five points: 80 mm bore, 18 mm stroke, PT3/8 port thread, basic mounting (no bracket), and the absence of a magnet. This ensures a direct dimensional and performance swap for another AirTAC SC80 tie-rod unit.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC80 Standard Cylinder SC80X18 FAQ
At 0.7 MPa operating pressure, the SC80X18 produces 3518 N of push force. The maximum push force at 0.9 MPa is 4523 N. Always size the cylinder based on the available plant air pressure.
No. The SC80X18 is a double-acting cylinder and will not hold its position if air pressure is exhausted or the directional valve is centred. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
