About the Airtac SC80 Standard Cylinder SC80X120
The AirTAC SC80X120 is a double-acting tie-rod cylinder that produces 2513 N of push force at 0.5 MPa (4523 N at the 0.9 MPa maximum operating pressure). Its 80 mm bore and 120 mm stroke suit medium-duty clamping, pressing, and material-transfer tasks where a compact footprint is needed.
This model uses a 25 mm diameter piston rod with M20×1.5 male threads and PT3/8 pneumatic ports. The body length A is 182 mm, giving a total extended length of approximately 302 mm. An adjustable air cushion on both ends decelerates the piston across a 28 mm cushion zone, reducing end-of-stroke shock.

Where the Airtac SC80 Standard Cylinder SC80X120 Is Used
Package Diverting
Pushes cartons off a belt at 0.5-0.7 MPa. The 120 mm stroke provides enough travel to clear the conveyor width without over-extending.
Clamping Fixtures
Delivers up to 4523 N of clamping force at 0.9 MPa. The adjustable cushion protects the fixture from impact during high-cycle operation.
Press-Fit Assembly
Generates controlled linear force for bearing or bushing insertion. The tie-rod construction allows easy maintenance in demanding assembly cells.
Is the Airtac SC80 Standard Cylinder SC80X120 the Right Cylinder?
Choose the SC80X120 when your application needs around 2500 N of force at standard plant air. If you require more force, step up to the SC100 bore (3927 N push at 0.5 MPa); for a lighter, faster-moving load, the SC63 bore delivers 1559 N at the same pressure. For strokes of 300 mm or longer, evaluate side-load conditions and consider an external guide or a guided cylinder to protect the rod bearing from bending moments.
To replace an existing cylinder, match five points: 80 mm bore, 120 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and confirm whether a magnet is needed. The SC series is a tie-rod design and 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 SC80X120 FAQ
At 0.7 MPa supply pressure, the SC80X120 generates 3518 N of push force and 2268 N of pull force on the retract stroke, based on the official AirTAC thrust table.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder, so mounting dimensions and overall length differ. Replace it only with another AirTAC SC80 cylinder of the same stroke, port thread, and mounting style.
