About the Airtac SC80 Standard Cylinder SC80X55S
The SC80X55S is an 80 mm bore, 55 mm stroke double-acting tie-rod cylinder from AirTAC's SC family, pre-configured with a built-in magnet for sensor feedback. At 0.5 MPa air pressure it generates 2513 N pushing force and 2268 N pulling force, placing it firmly in the medium-to-heavy industrial force class.
This model uses a 25 mm diameter piston rod with an M20x1.5 male rod thread and PT3/8 pneumatic ports. The adjustable air cushion at each end provides a 28 mm deceleration zone, and the magnet suffix -S allows CMSG, DMSG, or EMSG reed or solid-state sensors to clamp directly onto the barrel for end-of-stroke or mid-stroke position sensing.

Where the Airtac SC80 Standard Cylinder SC80X55S Is Used
Sorting Gate Actuation
The 55 mm stroke and magnetic piston sensing make this cylinder ideal for high-speed diverter gates on package conveyors, where end-of-stroke confirmation is required before the next cycle.
Clamping & Fixturing
Delivers a firm 2513 N clamping force at 0.5 MPa. The built-in magnet enables clamp-open and clamp-closed verification sensors, improving cycle safety on CNC fixtures and welding jigs.
Press-Fit Assembly
Used in short-stroke press-fit stations for bearings or bushings. The 80 mm bore provides ample force, while the magnetic piston signals the control system when the press stroke is complete.
Is the Airtac SC80 Standard Cylinder SC80X55S the Right Cylinder?
Choose the SC80 bore when your application needs roughly 2500 N of force at standard shop air; if you can accept a smaller footprint and around 1560 N, the 63 mm bore (SC63) saves space and weight. For higher force near 3900 N, step up to the 100 mm bore (SC100).
To ensure a correct replacement, match five points: 80 mm bore, 55 mm stroke, PT3/8 port thread, the built-in magnet (-S), and any mounting accessory you may add. 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 SC80X55S FAQ
At the standard operating pressure of 0.5 MPa, the cylinder produces 2513 N extending (push) and 2268 N retracting (pull). At the maximum operating pressure of 0.9 MPa, the push force increases to 4523 N.
Yes. The -S suffix in the model code SC80X55S indicates a built-in magnet in the piston. You can directly clamp AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors onto the barrel tie-rods to detect piston position.
