About the Airtac SC80 Standard Cylinder SC80X20
The AirTAC SC80X20 is a compact-stroke double-acting cylinder built on the 80 mm bore SC tie-rod platform, delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at the maximum operating pressure of 0.9 MPa. With a 20 mm stroke and a 25 mm diameter piston rod, it is well-suited for short-throw clamping, ejecting, or positioning tasks where space is tight but high force is required.
The body length A is 182 mm, giving a total extended length of approximately 202 mm. An adjustable pneumatic cushion (28 mm length) decelerates the piston at each end of travel, reducing impact and noise. The standard PT1/4 ports and M20x1.5 rod thread keep connections straightforward for industrial pneumatic circuits.

Where the Airtac SC80 Standard Cylinder SC80X20 Is Used
Short-Stroke Clamping
The 20 mm stroke and 2513 N force at 0.5 MPa make this cylinder ideal for pneumatic clamping fixtures where the jaw travel is minimal but the holding force must be high.
Part Ejection
Use the SC80X20 to eject parts from a die or mould. The short, powerful stroke reliably pushes components clear without taking up excessive machine depth.
Diverter Gate Actuation
Actuate a small diverter gate on a conveyor line. The cylinder provides the necessary force to redirect packages with a fast, repeatable 20 mm linear movement.
Is the Airtac SC80 Standard Cylinder SC80X20 the Right Cylinder?
This 80 mm bore model is a step up from the SC63 (1559 N at 0.5 MPa) for applications needing higher clamping or pressing force. If your load requires less force, stepping down to the 63 mm bore can reduce air consumption. For strokes of 300 mm or longer, evaluate side loads carefully—the rod bearing supports the 25 mm rod, but an external guide or guided cylinder is recommended for off-axis forces.
For a direct replacement, match five points: 80 mm bore, 20 mm stroke, PT1/4 port thread, basic mounting (no bracket), and the absence of a magnet. This is a tie-rod cylinder; it is not dimensionally interchangeable with ISO 15552 profile cylinders.
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 SC80X20 FAQ
At the standard operating pressure of 0.5 MPa, the push force is 2513 N. At 0.7 MPa it is 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N. The theoretical maximum force at 1.0 MPa is 513 kgf.
No. The AirTAC SC series is a tie-rod cylinder that is shorter in overall length than a comparable ISO 15552 cylinder. It is not dimensionally interchangeable. Replace it only with another AirTAC SC80 tie-rod cylinder matching the 20 mm stroke, PT ports, and basic mounting.
