About the Airtac SC80 Standard Cylinder SC80X390
The SC80X390 is an 80 mm bore double-acting pneumatic cylinder delivering a push force of 2513 N at 0.5 MPa and up to 4523 N at 0.9 MPa. With a 390 mm stroke, this model is well-suited for medium-duty linear tasks requiring a compact footprint, as the SC series body is shorter than an equivalent ISO 15552 cylinder.
This tie-rod cylinder features a 25 mm diameter piston rod with M20x1.5 threads and a 28 mm adjustable air cushion at each end. The total extended body length is approximately 572 mm (body length A of 182 mm plus the 390 mm stroke), providing a solid working envelope for pressing, clamping, and material handling stations.

Where the Airtac SC80 Standard Cylinder SC80X390 Is Used
Conveyor Diverting
The 390 mm stroke pushes packages off a main belt onto a spur line, handling the 2513 N force needed to move heavy totes reliably at 0.5 MPa line pressure.
Waste Compaction
Generates up to 4523 N at 0.9 MPa to compress cardboard or plastic waste in a small baler, with the 28 mm cushion absorbing impact at the end of the compacting stroke.
Automated Fixture Clamping
Applies consistent clamping force on a welding or assembly fixture. The 25 mm rod resists deflection under the 390 mm extension when guided tooling is used.
Is the Airtac SC80 Standard Cylinder SC80X390 the Right Cylinder?
Choose the SC80 when the SC63's 1559 N push force at 0.5 MPa is marginal for your load. If you need more force, stepping up to the SC100 provides 3927 N at the same pressure. For this 390 mm stroke, ensure the rod is not subjected to significant side loading; an external guide or a guided cylinder is recommended to protect the rod bearing and seals from bending stress.
To replace an existing cylinder, match five points exactly: 80 mm bore, 390 mm stroke, PT3/8 port thread, basic mounting (no bracket), and no magnet. This model uses the default TPU seals and PT threads, so confirm your current unit has the same configuration.
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 SC80X390 FAQ
At 0.5 MPa (approx. 73 psi) the cylinder pushes with 2513 N. At the standard industrial pressure of 0.7 MPa it delivers 3518 N, and at the maximum operating pressure of 0.9 MPa it reaches 4523 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. Only replace another AirTAC SC80 tie-rod cylinder with the same bore, stroke, and port thread.
