About the Airtac SE50 Standard Cylinder SE50AX280
The AirTAC SE50AX280 is a double-acting, single-rod ISO 15552 profile cylinder engineered for a 50 mm bore and 280 mm stroke. It generates 982 N of push force at 0.5 MPa and 1374 N at 0.7 MPa. The square extruded aluminum barrel omits external tie rods, yielding a compact footprint that mounts flush against frames while resisting corrosion in wet environments.
This specific SKU features a SUS420J2 stainless steel rod (code A) for superior resistance to rust and washdown chemicals. The unit includes field-adjustable pneumatic cushioning at both ends to decelerate the piston near stroke limits, though it lacks a built-in position-sensing magnet. It operates at speeds from 30-800 mm/s using a PT1/4 port.

Where the Airtac SE50 Standard Cylinder SE50AX280 Is Used
Food Processing Diverter
The SUS420J2 stainless rod withstands daily washdowns while actuating 280 mm divert gates in packaged food lines, utilizing 982 N push force.
Carton Flap Folder
Provides reliable 280 mm travel to fold large corrugated carton flaps, where the adjustable end cushions soften high-speed impacts to protect packaging.
Beverage Bottle Aligner
Sweeps and aligns plastic bottles on a high-speed conveyor, relying on the smooth profile barrel and 825 N retract force to clear jams.
Is the Airtac SE50 Standard Cylinder SE50AX280 the Right Cylinder?
Delivering 982 N push at 0.5 MPa, this 50 mm bore fits medium-duty cycling. If your application requires less force, the 40 mm bore offers 628 N push, while stepping up to the 63 mm bore provides 1559 N for heavier loads. Because this is a 280 mm stroke, the unsupported piston rod is prone to bending under side loads; always use an external guide bearing to prevent premature seal wear. This standard profile cylinder serves as a drop-in dimensional replacement for any ISO 15552 cylinder, sharing identical mounting interface dimensions and PT1/4 port locations.
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 SE50 Standard Cylinder SE50AX280 FAQ
The SE50AX280 generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum push of 200 kgf at 1.0 MPa. It operates at 0.15-1.0 MPa with a speed range of 30-800 mm/s.
No, the adjustable air cushion only decelerates the piston near stroke end and is not a locking mechanism. If you need to hold a load without live air pressure, you must use an external pilot-operated check valve or a BSE rod lock cylinder.
