About the Airtac SC80 Standard Cylinder SC80X800SH
The SC80X800SH is a double-acting pneumatic cylinder delivering 2513 N of push force at 0.5 MPa, scaling to 4523 N at the 0.9 MPa maximum operating pressure. With an 80 mm bore and 800 mm stroke, this tie-rod actuator uses a 25 mm diameter piston rod and PT3/8 ports, providing a robust linear motion solution for medium-to-heavy automation tasks.
This variant includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise end-of-stroke or mid-stroke position feedback without external brackets. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making it suitable for hot environments where standard TPU seals would degrade. The 28 mm adjustable air cushion at each end decelerates the piston smoothly, protecting the end caps during high-speed cycling.

Where the Airtac SC80 Standard Cylinder SC80X800SH Is Used
High-Temperature Process Automation
Viton seals allow this cylinder to operate reliably in ovens, autoclaves, and foundry equipment up to 150°C, where standard seals would fail.
Long-Stroke Material Transfer
The 800 mm stroke and 2513 N push force efficiently transfer heavy components between conveyor lines or into machining centres.
Sensor-Monitored Pressing
The built-in magnet enables CMSG/DMSG sensors to confirm clamp or press position, ensuring consistent force application in assembly fixtures.
Is the Airtac SC80 Standard Cylinder SC80X800SH the Right Cylinder?
For applications requiring slightly less force, the 63 mm bore SC63 series provides 1559 N at 0.5 MPa, while stepping up to the 100 mm bore SC100 delivers 3927 N. At an 800 mm stroke, the 25 mm rod is long and susceptible to bending under side loads; always guide the load externally with a linear rail or rod guide, or consider a guided cylinder if lateral forces are present. To ensure a drop-in replacement, match five key specifications: 80 mm bore, 800 mm stroke, PT3/8 port thread, the built-in magnet (-S), and the Viton seal material (-H). This cylinder is not dimensionally interchangeable with ISO 15552 profile cylinders.

- ✓ 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 SC80X800SH FAQ
At 0.7 MPa operating pressure, the theoretical push force is 3518 N and the pull force on the retract stroke is 3165 N (accounting for the 25 mm rod area).
No. As a standard double-acting cylinder, it will drift or drop if pressure is exhausted. For load holding without live pressure, you must add an external pilot-operated check valve or a mechanical rod lock.
