About the Airtac SC80 Standard Cylinder SC80X340S
The SC80X340S delivers 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa, making it a robust mid-range actuator for industrial automation. Its 25 mm diameter rod and 28 mm adjustable air cushion provide reliable deceleration for the 340 mm stroke, while the built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for precise end-of-stroke detection.
With a body length A of 182 mm, this double-acting tie-rod cylinder is more compact than an ISO 15552 profile, suiting installations where space is limited. The PT3/8 port and M20x1.5 rod thread offer standard pneumatic connectivity, and the TPU seals ensure smooth operation from -20 to +70 °C.

Where the Airtac SC80 Standard Cylinder SC80X340S Is Used
Material Handling Gates
Operates diverter gates and stops on conveyor lines, where the 2513 N force at 0.5 MPa reliably redirects packages or pallets, and the magnetic sensors confirm gate position.
Press-Fit Assembly
Delivers up to 4523 N at 0.9 MPa for pressing bearings, bushings, or pins into housings, with the adjustable cushion absorbing impact at the end of the 340 mm stroke.
Pallet Stacking Systems
Pushes empty pallets into a stacker magazine. The CMSG/DMSG sensors detect full extension and retraction, ensuring the stacker indexes correctly for each cycle.
Is the Airtac SC80 Standard Cylinder SC80X340S the Right Cylinder?
For lighter loads, stepping down to the 63 mm bore reduces push force to 1559 N at 0.5 MPa, while moving up to the 100 mm bore provides 3927 N. The 340 mm stroke is within the 1500 mm maximum standard stroke for this bore, but the extended rod length increases the risk of side-load bending; use an external guide or guided cylinder if the load is not purely axial. To match this exact configuration for replacement, verify bore (80 mm), stroke (340 mm), PT port thread, the built-in magnet (-S suffix), and basic mounting.
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 SC80X340S 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, push force reaches 4523 N. The theoretical maximum at 1.0 MPa is 513 kgf.
No. The SC series is a tie-rod cylinder with a shorter body length than an ISO 15552 cylinder, so mounting dimensions and overall length are not interchangeable. It directly replaces another AirTAC SC80 cylinder with the same bore, stroke, PT port, and magnet option.
