About the Airtac SC80 Standard Cylinder SC80X75SH
The SC80X75SH is a double-acting pneumatic cylinder delivering 2513 N push force at 0.5 MPa, built on an 80 mm bore with a 25 mm diameter piston rod. Its 75 mm stroke suits short clamping and ejector tasks, while the 28 mm adjustable air cushion at each end decelerates the piston smoothly to protect tooling.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, enabling rod-position feedback without external brackets. The Viton (FKM) seal package (-H) shifts the operating temperature range to 0–150 °C, making it a reliable choice for autoclaves, foundries, and hot-process automation.

Where the Airtac SC80 Standard Cylinder SC80X75SH Is Used
Hot-Process Actuation
Viton seals sustain reliable double-acting motion in ovens, autoclaves, and steam lines up to 150°C ambient, where standard seals would degrade.
Sensor-Monitored Clamping
The built-in magnet allows CMSG/DMSG sensors to confirm full clamp extension and retraction on automated welding or assembly fixtures.
Short-Stroke Part Ejection
With 2513 N of push force, this 75 mm stroke cylinder ejects heavy castings or molded parts from dies onto a conveyor without over-travel.
Is the Airtac SC80 Standard Cylinder SC80X75SH the Right Cylinder?
For applications needing more force, the 100 mm bore SC100 series provides 3927 N push at 0.5 MPa. If a shorter, lighter cylinder is acceptable, the 63 mm bore SC63 delivers 1559 N at the same pressure. At 75 mm stroke, rod bending is minimal, but any side load should be managed with an external linear guide.
To replace an existing cylinder, match five points: 80 mm bore, 75 mm stroke, PT port thread, the -S magnet option for sensors, and the -H Viton seal for high-temperature compatibility. This is a tie-rod cylinder, not an ISO 15552 profile, so dimensional interchangeability is limited to other AirTAC SC80 units.
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 SC80X75SH FAQ
At 0.7 MPa operating pressure, the 80 mm bore generates 3518 N of push force and 2268 N of pull force. The theoretical maximum at 1.0 MPa is 513 kgf.
The built-in magnet works with AirTAC CMSG (reed) and DMSG/EMSG (solid-state) sensors. However, for ambient temperatures above 70°C, use solid-state sensors rated for the actual environment, as reed switches have lower thermal limits.
