About the Airtac SE80 Standard Cylinder SE80X312S
The AirTAC SE80X312S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty positioning. It delivers a robust 2513 N push at 0.5 MPa and 3518 N at 0.7 MPa, utilizing an 80 mm bore and a 312 mm stroke. Because the stroke exceeds the standard 1500 mm maximum for this bore size, it is supplied as a made-to-order unit.
This actuator features an extruded aluminum barrel without external tie rods, yielding a compact, corrosion-resistant footprint that mounts flush within tight machine frames. The integrated -S magnet enables direct fitment of CMSE reed and DMSE electronic sensors along the three integrated side grooves. Furthermore, the field-adjustable pneumatic cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration, effectively softening hard impacts during high-speed operations.

Where the Airtac SE80 Standard Cylinder SE80X312S Is Used
Palletizer Case Pusher
Drives heavy corrugated cases onto pallets using the 2513 N push force, while the 312 mm stroke provides the exact reach needed to clear the wrapping station.
Injection Mold Extractor
Utilizes the 80 mm bore to pull dense molded parts from heavy tooling, relying on the -S magnet and DMSE electronic sensors to confirm safe extraction before the press opens.
Metal Stamping Ejector
Pushes stamped sheet metal components from press dies, using the field-adjustable end cushions to soften the abrupt deceleration of heavy slugs at high cycle rates.
Is the Airtac SE80 Standard Cylinder SE80X312S the Right Cylinder?
Stepping down to the 63 mm bore reduces the 0.5 MPa push to 1559 N, whereas upgrading to the 100 mm bore increases it to 3927 N, allowing you to balance speed and load precisely. As a standard ISO 15552 profile cylinder, this unit is dimensionally interchangeable with other ISO 15552 cylinders, sharing identical mounting hardware like FA front flanges or TC trunnions.
At 312 mm of stroke, the 25 mm rod and internal bearing face increased bending moments under side loads; for offset loads, incorporating an external guide rail is strongly recommended to prevent premature wear. Note that while the adjustable air cushion decelerates the piston near stroke end, it does not lock or hold the load—if air pressure is lost or the valve is centered, the rod will drift. For true position holding, consider the BSE rod lock variant.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for CMSE/DMSE 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 (LB/FA/FB/CA/CB/CR/TC/FTC/TCM1/TCM2).
- check Installation by qualified personnel per AirTAC docs.
