About the Airtac SC80 Standard Cylinder SC80X25N
The SC80X25N is a compact-stroke double-acting pneumatic cylinder from the AirTAC SC tie-rod series, featuring an 80 mm bore and a 25 mm stroke. At 0.5 MPa operating pressure, it generates a push force of 2513 N, making it suitable for short-throw clamping, ejecting, and pressing tasks where space is limited.
This model is fitted with NBR (nitrile) seals as standard, offering reliable performance within the standard temperature range of -20 to +70 °C. The 25 mm diameter piston rod with M20x1.5 male thread provides robust guidance, while the 28 mm adjustable air cushion at each end decelerates the piston smoothly to reduce end-of-stroke impact noise.

Where the Airtac SC80 Standard Cylinder SC80X25N Is Used
Short-Stroke Clamping
The 25 mm stroke and 2513 N force at 0.5 MPa make this cylinder ideal for compact pneumatic clamping fixtures in machining and assembly cells.
Part Ejection
Delivers a quick, powerful push to eject parts from injection molds or stamping dies where tooling clearance is minimal.
Diverter Gates
Actuates small diverter gates or stops on conveyor lines, providing a decisive 25 mm linear movement for product sorting.
Is the Airtac SC80 Standard Cylinder SC80X25N the Right Cylinder?
For applications requiring more force, stepping up to the SC100 bore provides 3927 N of push force at the same 0.5 MPa pressure. If a longer stroke is needed, the SC80 bore supports standard strokes up to 1500 mm. The SC80X25N uses PT1/4 ports and a basic mount configuration with no built-in magnet.
When replacing this cylinder, match five key points: 80 mm bore, 25 mm stroke, PT port thread, NBR seal material, and the basic (no bracket) mounting style. For short-stroke applications, ensure the load is aligned axially to prevent uneven rod bearing wear.
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 SC80X25N FAQ
At 0.7 MPa operating pressure, the SC80X25N double-acting cylinder produces a theoretical push force of 3518 N. The pull force at the same pressure is 2268 N, accounting for the 25 mm rod diameter.
No, the SC80X25N is sealed with NBR (nitrile) and is rated for -20 to +70 °C. For high-temperature applications up to 150 °C, select the 'H' suffix variant (SC80X25H) which uses Viton (FKM) seals.
