About the Airtac SC80 Standard Cylinder SC80X125CA
The SC80X125CA is an 80 mm bore, 125 mm stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series. It delivers 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, driven by a 25 mm diameter piston rod with an M20x1.5 male thread. The adjustable air cushion at each end (28 mm cushion length) decelerates the piston smoothly, reducing end-of-stroke impact.
This model is configured with a rear single clevis mount (CA type), using the F-SC80CA accessory for pivoting attachment. The standard PT1/8 port thread and TPU seals suit general industrial air service from -20 to +70 °C. With a body length of 182 mm, the total extended length is approximately 307 mm, making it a compact choice for medium-stroke clamping and pressing tasks.

Where the Airtac SC80 Standard Cylinder SC80X125CA Is Used
Part Diverter Gate
The 125 mm stroke and rear clevis mount allow the cylinder to pivot, actuating a diverter gate on a conveyor line. The 2513 N force at 0.5 MPa reliably shifts packages or components between lanes.
Clamping Fixture
Delivers up to 4523 N of clamping force at 0.9 MPa for workholding in CNC machining or welding fixtures. The adjustable cushion prevents hammering at full extension, protecting the fixture.
Hopper Door Actuator
The rear clevis pivot and 80 mm bore provide the robust force needed to open and close a heavy hopper discharge door, handling the high cycle counts common in agricultural processing.
Is the Airtac SC80 Standard Cylinder SC80X125CA the Right Cylinder?
Choose the SC80 when your application needs between 2513 N and 4523 N of pneumatic force. If your load is lighter, the 63 mm bore (1559 N at 0.5 MPa) may reduce air consumption; for heavier work, the 100 mm bore (3927 N at 0.5 MPa) offers a significant step up. The 125 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
For replacement, match five key points: 80 mm bore, 125 mm stroke, PT port thread, rear single clevis (CA) mounting, and no magnet. This is a tie-rod cylinder, shorter than an ISO 15552 profile, so it is not a drop-in replacement for ISO 15552 cylinders. Always verify the clevis pin diameter and the overall extended length against your existing setup.
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 SC80X125CA FAQ
At 0.7 MPa operating pressure, the SC80 cylinder produces 3518 N of push force and 2268 N of pull force on the retract stroke. The maximum push force at 0.9 MPa is 4523 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 profile cylinder. The SC80 has a body length A of 182 mm. It is not dimensionally interchangeable with ISO 15552 cylinders. It is a direct replacement only for another AirTAC SC80 tie-rod cylinder with matching stroke, port, and mounting.
