About the Airtac SC80 Standard Cylinder SC80X344S
The AirTAC SC80X344S is a double-acting single-rod pneumatic cylinder delivering 2513 N push force at 0.5 MPa and up to 4523 N at 0.9 MPa operating pressure. Its 25 mm diameter rod and 28 mm adjustable air cushion provide reliable end-of-stroke deceleration for a 344 mm stroke, making it a solid mid-range actuator for general automation.
This model features a built-in magnet (suffix -S), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the tie-rod barrel for non-contact position sensing. The SC series is a tie-rod design, shorter than an ISO 15552 cylinder, with PT1/8 ports and an M20x1.5 rod thread.

Where the Airtac SC80 Standard Cylinder SC80X344S Is Used
Material Handling Gates
The 2513 N push force at 0.5 MPa easily operates diverter gates and stops on conveyor lines, while the built-in magnet enables end-of-stroke confirmation with CMSG sensors.
Clamping & Pressing Fixtures
Delivers up to 4523 N at 0.9 MPa for holding parts during machining or assembly. The adjustable cushion protects tooling by softening impact at the end of the 344 mm stroke.
Palletising Pushers
The 344 mm stroke provides enough reach to push boxes or trays onto a pallet. The magnet allows sensor feedback to verify full extension and retraction in automated cells.
Is the Airtac SC80 Standard Cylinder SC80X344S the Right Cylinder?
For applications needing more force, stepping up to the SC100 bore provides 3927 N at 0.5 MPa. If space is tight and the load is lighter, the SC63 bore delivers 1559 N. The 344 mm stroke is within the 1500 mm max standard stroke for 80 mm bore, but always check for side loads: an unsupported rod at this extension can bend under radial force—consider an external guide or a guided cylinder if the load is not purely axial.
When replacing an existing unit, match five points: 80 mm bore, 344 mm stroke, PT1/8 port thread, the built-in magnet (-S) for sensor compatibility, and the basic (no bracket) mounting style. 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 SC80X344S FAQ
At 0.5 MPa, 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 reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
Yes. The -S suffix means this cylinder has a built-in magnet, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position.
