About the Airtac SE80 Standard Cylinder SE80X303SN
The AirTAC SE80X303SN is a double-acting single-rod profile cylinder built to ISO 15552 dimensions, delivering a robust 2513 N push force at 0.5 MPa. Its square extruded aluminum barrel removes the need for external tie rods, yielding a compact, flush-mounting body that resists corrosion and simplifies fixture integration. The NBR seal accommodates standard industrial temperatures, while the built-in magnet enables seamless position tracking.
This non-standard 303 mm stroke unit utilizes a Ø25 mm piston rod and PT3/8 ports. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration, preventing hard impacts during high-speed 30-800 mm/s operations. The cushioning only slows the piston near stroke end and does not lock the rod in place.

Where the Airtac SE80 Standard Cylinder SE80X303SN Is Used
Pallet Diverting Gate
Leverages the 2513 N push force to pivot heavy pallet diverters on high-throughput packaging lines, using the 303 mm stroke to clear wide conveyor lanes.
Corrugated Box Flap Folder
Drives the folding mechanism on automated carton erectors, relying on the adjustable pneumatic cushion to soften the impact of rapid 30-800 mm/s strokes.
Injection Mold Platen Ejector
Pushes finished plastic parts from a molding press platen, where the NBR seals withstand typical factory heat and the magnetic piston tracks ejection completion.
Is the Airtac SE80 Standard Cylinder SE80X303SN the Right Cylinder?
Selecting this 80 mm bore provides 2513 N of push at 0.5 MPa; if your payload is lighter, the 63 mm bore offers 1559 N, while stepping up to the 100 mm bore yields 3927 N for heavier loads. Because this is a non-standard 303 mm stroke made-to-order, it provides exact travel for custom machine spacing. As an ISO 15552 profile cylinder, it serves as a drop-in replacement sharing standard mounting accessories.
With a 303 mm stroke, the unsupported rod length increases bending moments under side loads; utilize an external guide rail to prevent rod-bearing wear. Note that a plain SE cylinder drifts when air pressure is lost—use a BSE rod lock variant if the application requires mechanical load holding.
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.
Airtac SE80 Standard Cylinder SE80X303SN FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N, with a maximum push capacity of 513 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE80X303SN shares the exact ISO 15552 / VDMA 24562 mounting interface and dimensions, allowing it to serve as a drop-in replacement for other ISO 15552 profile cylinders. It uses PT3/8 ports and an M20x1.5 rod thread, and the built-in magnet works with AirTAC CMSE and DMSE sensors.
