About the Airtac SC80 Standard Cylinder SC80X270SH
The SC80X270SH is a double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa and 4523 N at the 0.9 MPa maximum operating pressure. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration for the 270 mm stroke, making it suitable for medium-duty linear tasks in hot environments.
This model is configured with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, and Viton (FKM) seals (-H suffix) that shift the operating temperature range to 0–150°C. The body length A is 182 mm, with PT1/8 ports, and the total extended length is approximately 452 mm.

Where the Airtac SC80 Standard Cylinder SC80X270SH Is Used
High-Temperature Actuation
Viton seals enable reliable operation in ovens, autoclaves, and foundry equipment where ambient temperatures reach up to 150°C, with 2513 N of force at standard line pressure.
Hot-Material Sorting Gate
The 270 mm stroke and built-in magnet for end-of-stroke sensing make it ideal for diverting hot glass, metal, or plastic parts on a conveyor line.
Press and Clamping Fixtures
Delivers a strong 4523 N clamping force at 0.9 MPa for holding workpieces during welding or heat-assisted forming processes, with adjustable cushioning to reduce cycle shock.
Is the Airtac SC80 Standard Cylinder SC80X270SH the Right Cylinder?
For applications needing more force, stepping up to the 100 mm bore provides 3927 N at 0.5 MPa. If a shorter, more compact cylinder is acceptable, the 63 mm bore offers 1559 N. The 270 mm stroke is well within the 1500 mm maximum standard stroke for this bore, but always ensure the rod is guided externally if any side load is present, as the 25 mm rod can bend under unsupported lateral forces.
To replace an existing cylinder, match five points: 80 mm bore, 270 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. The SC 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 SC80X270SH FAQ
At 0.7 MPa operating pressure, the push force is 3518 N, and the pull force on the return stroke is 3168 N. The maximum push force at 0.9 MPa is 4523 N.
No. The AirTAC SC series is a tie-rod cylinder with a shorter overall body length than an ISO 15552 cylinder. It is a direct replacement only for another SC80 tie-rod cylinder with matching bore, stroke, PT ports, magnet, and Viton seals.
