About the Airtac SC80 Standard Cylinder SC80X12
The SC80X12 is a compact-stroke variant in the AirTAC SC tie-rod family, 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 an 80 mm bore and a 25 mm diameter piston rod, this double-acting cylinder is built for short, precise linear movements where space is limited.
Its 12 mm stroke is well within the standard range for the 80 mm bore, which supports strokes up to 1500 mm. The body length A is 182 mm, giving a total extended length of approximately 194 mm. The adjustable pneumatic cushion (28 mm length) decelerates the piston at end-of-stroke to reduce impact, while the PT3/8 port threads ensure straightforward pneumatic connections.

Where the Airtac SC80 Standard Cylinder SC80X12 Is Used
Short-Stroke Clamping
The 12 mm stroke and 2513 N force at 0.5 MPa make this cylinder perfect for pneumatic clamping fixtures in woodworking or metal fabrication, where a quick, powerful, and short linear motion is needed.
Part Ejection
Ideal for ejecting parts from a die or mold. The rapid 30-800 mm/s speed range and compact extended length allow it to fit into tight tooling spaces on stamping or injection molding machines.
Diverter Gate Actuator
Use the SC80X12 to actuate a small diverter gate on a conveyor line. Its robust 25 mm rod and tie-rod construction handle the repetitive impact of sorting packages or components.
Is the Airtac SC80 Standard Cylinder SC80X12 the Right Cylinder?
For applications needing slightly less force in a smaller envelope, the 63 mm bore SC63 series provides 1559 N push at 0.5 MPa. If your load demands higher force, stepping up to the 100 mm bore SC100 series yields 3927 N at the same pressure. This short 12 mm stroke model is ideal for clamping, ejecting, or stopping functions.
When replacing an existing cylinder, match five key points: 80 mm bore, 12 mm stroke, PT3/8 port thread, basic (no bracket) mounting, and the absence of a magnet. The SC is a tie-rod cylinder 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 SC80X12 FAQ
At 0.5 MPa the push force is 2513 N. At the standard 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 with a shorter overall body length than an ISO 15552 cylinder of the same bore and stroke. It is only dimensionally interchangeable with another AirTAC SC tie-rod cylinder matching the 80 mm bore, 12 mm stroke, and PT3/8 port thread.
