About the Airtac SC80 Standard Cylinder SC80X25SH
The SC80X25SH is an 80 mm bore double-acting tie-rod cylinder with a compact 25 mm stroke, delivering a push force of 2513 N at 0.5 MPa. Its 25 mm diameter rod and PT3/8 port thread suit short, high-force clamping, pressing, or ejection tasks where space is tight.
This model is factory-equipped with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H) that shift the operating temperature range to 0 to +150 °C. The adjustable air cushion (28 mm length) decelerates the piston smoothly at end-of-stroke, protecting the end caps during rapid cycling.

Where the Airtac SC80 Standard Cylinder SC80X25SH Is Used
Hot Press Clamping
Viton seals allow this cylinder to operate reliably in heated press fixtures up to 150 °C, applying 2513 N of clamping force at 0.5 MPa.
Sensor-Controlled Ejection
The built-in magnet works with barrel-mounted reed sensors to confirm full extension and retraction during high-speed part ejection in automated assembly cells.
Autoclave Door Actuation
Withstands repeated high-temperature washdown cycles in autoclave or sterilisation equipment, providing reliable short-stroke door opening and closing.
Is the Airtac SC80 Standard Cylinder SC80X25SH the Right Cylinder?
For higher force at the same pressure, step up to the 100 mm bore (3927 N at 0.5 MPa); for a lighter, faster actuator, the 63 mm bore offers 1559 N. The 25 mm stroke is well within the 1500 mm maximum standard stroke for this bore. When replacing, match bore (80 mm), stroke (25 mm), PT port thread, the built-in magnet sensor option, and the Viton seal material to ensure identical performance and temperature tolerance.
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 SC80X25SH FAQ
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC80X25SH is a double-acting cylinder that requires continuous air pressure to maintain position. If pressure is exhausted or the directional valve is centered, the piston will drift. Use an external rod lock or pilot-operated check valve for static load holding.
