About the Airtac SC80 Standard Cylinder SC80X280SH
The SC80X280SH is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa. With an 80 mm bore and a 280 mm stroke, it features a 25 mm diameter piston rod and a 28 mm adjustable air cushion at each end to decelerate the load smoothly.
This model is equipped with a built-in magnet (-S suffix) for direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel, enabling non-contact position sensing. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C for hot or chemically aggressive environments. Ports are standard PT1/8.

Where the Airtac SC80 Standard Cylinder SC80X280SH Is Used
High-Temperature Actuation
Viton seals enable reliable operation in autoclaves, drying ovens, and foundry equipment where ambient temperatures reach up to 150°C.
Sensor-Monitored Clamping
The built-in magnet allows CMSG/DMSG sensors to confirm clamp position on automated welding and assembly fixtures, ensuring cycle safety.
Material Sorting Gate
With 2513 N of push force at 0.5 MPa, this cylinder easily diverts heavy packages on high-speed conveyor lines, with sensor feedback confirming gate status.
Is the Airtac SC80 Standard Cylinder SC80X280SH the Right Cylinder?
For applications requiring less force, consider stepping down to the 63 mm bore SC63 series, which provides 1559 N at 0.5 MPa. If a higher force is needed, the 100 mm bore SC100 series offers 3927 N at the same pressure. At a 280 mm stroke, the 25 mm rod is robust, but any significant side load requires an external linear guide or rod support to prevent bending and premature bearing wear.
To replace an existing unit, match five key points: 80 mm bore, 280 mm stroke, PT1/8 port thread, the built-in magnet for sensors, and the Viton seal material for high-temperature compatibility. This 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 SC80X280SH FAQ
At the standard operating pressure of 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 increases to 4523 N.
No. The SC80X280SH is a double-acting cylinder and will not hold its position if air pressure is exhausted or lost. The piston can drift or drop. For load holding without live pressure, you must add an external rod brake, a mechanical lock, or a pilot-operated check valve.
