About the Airtac SC80 Standard Cylinder SC80X120SH
The AirTAC SC80X120SH is a double-acting tie-rod cylinder delivering 2513 N push force at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa. Its 25 mm diameter piston rod and 28 mm adjustable air cushion provide smooth deceleration for the 120 mm stroke, making it a robust choice for medium-duty linear tasks.
This model is factory-equipped with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The -H suffix specifies Viton (FKM) seals, shifting the operating temperature range to 0 to +150 °C for reliable performance in hot environments.

Where the Airtac SC80 Standard Cylinder SC80X120SH Is Used
High-Temperature Actuation
Viton seals allow this cylinder to operate in ambient temperatures up to 150°C, making it suitable for pressing, drying, or autoclave equipment where standard seals would fail.
Sorting & Diverting Gates
With 2513 N of push force at 0.5 MPa, it reliably actuates heavy-duty diverters on conveyor lines. The built-in magnet allows easy addition of sensors to confirm gate position.
Hot-Mold Clamping
Delivers consistent clamping force for injection or compression molds. The adjustable cushion protects tooling by decelerating the 25 mm rod smoothly at the end of the 120 mm stroke.
Is the Airtac SC80 Standard Cylinder SC80X120SH the Right Cylinder?
Choose the SC80 bore when your application requires a push force of around 2513 N at standard plant pressure. If the load is lighter, stepping down to an SC63 (1559 N at 0.5 MPa) can reduce air consumption and physical size. For heavier demands, the SC100 bore provides 3927 N at the same pressure.
To ensure a successful replacement, match five key points: 80 mm bore, 120 mm stroke, PT port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. This cylinder is a direct fit for another AirTAC SC80X120SH unit.

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 SC80X120SH FAQ
At 0.7 MPa operating pressure, the SC80 bore generates a theoretical push force of 3518 N. The pull force on the retract stroke is 2268 N at 0.5 MPa, due to the area reduction from the 25 mm piston rod.
Yes. The -S suffix in the model code indicates a built-in magnet is integrated into the piston. This allows you to mount AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the tie-rod barrel to detect end-of-stroke or intermediate positions.
