About the Airtac SC80 Standard Cylinder SC80X140S
The AirTAC SC80X140S is a double-acting tie-rod cylinder equipped with a built-in magnet, enabling direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for precise end-of-stroke or mid-stroke position feedback. With an 80 mm bore and 140 mm stroke, it produces 2513 N of push force at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa, driven by a 25 mm diameter piston rod.
This model uses the standard PT1/4 port thread and TPU/NBR seals rated for -20 to +70 °C. The adjustable air cushion at each end (28 mm length) decelerates the piston smoothly, and the body length A is 182 mm, giving a total extended length of approximately 322 mm. It is a genuine AirTAC SC-series cylinder, factory-tested to a 1.5 MPa proof pressure for reliable industrial service.

Where the Airtac SC80 Standard Cylinder SC80X140S Is Used
Automated Sorting Gates
The 140 mm stroke and built-in magnet make this cylinder ideal for diverting packages on conveyor lines. Magnetic sensors confirm gate position at each cycle, preventing jams and ensuring reliable sortation.
Clamping & Staking Fixtures
Delivers up to 4523 N of clamping force at 0.9 MPa for holding parts during machining or assembly. The sensor magnet allows the control system to verify the clamp is fully engaged before the cycle starts.
Press & Forming Assist
Used as a low-pressure assist cylinder in small forming or press tools, the SC80X140S provides consistent linear force. The adjustable cushion protects tooling by softening the impact at the end of the 140 mm stroke.
Is the Airtac SC80 Standard Cylinder SC80X140S the Right Cylinder?
Select the SC80 bore when your application needs between 2513 N and 4523 N of pneumatic force. If your load requires less, stepping down to the SC63 bore saves space and air consumption while still providing 1559 N at 0.5 MPa. For higher force demands, the SC100 bore delivers 3927 N at the same 0.5 MPa supply pressure.
To ensure a correct replacement, match five points: 80 mm bore, 140 mm stroke, PT1/4 port thread, the built-in magnet (-S suffix), and the basic mounting configuration. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders; it must replace another AirTAC SC or equivalent tie-rod design with the same port and mounting pattern.
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 SC80X140S FAQ
At the standard 0.5 MPa operating pressure, 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. The theoretical maximum force at 1.0 MPa is 513 kgf.
Yes. The -S suffix in the model code indicates a built-in magnet on the piston. This allows you to clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel tie-rods or sensor slots to detect piston position without any modification.
