About the Airtac SE50 Standard Cylinder SE50AX280S
The AirTAC SE50AX280S is a double-acting single-rod ISO 15552 profile cylinder delivering 982 N of push force at 0.5 MPa. It features a SUS420J2 stainless steel rod (code A) designed specifically for corrosive and washdown environments. The square extruded aluminum barrel lacks external tie rods, yielding a compact footprint that mounts flush against machine frames while preventing localized corrosion pockets.
This 50 mm bore unit includes a built-in magnet (code S) for non-contact position sensing with AirTAC CMSE reed or DMSE electronic switches. Field-adjustable air cushions at both ends allow mechanics to tune end-of-stroke deceleration, softening hard impacts during high-speed cycling. Operating pressure spans 0.15-1.0 MPa, and the PT1/4 port ensures robust pneumatic connectivity.

Where the Airtac SE50 Standard Cylinder SE50AX280S Is Used
Pouch Sealing Press
Drives a 280 mm sealing jaw in a packaging line, using the 982 N push force to crimp laminated films while the SUS420J2 rod shrugs off daily washdowns.
Sorter Diverter Arm
Actuates a routing gate at 30-800 mm/s, leveraging the 280 mm stroke to clear the conveyor lane fully before returning for the next parcel.
Lab Sample Ejector
Ejects processed vials from a testing carousel, where the SUS420J2 stainless rod prevents chemical corrosion from reagent spills.
Is the Airtac SE50 Standard Cylinder SE50AX280S the Right Cylinder?
This 50 mm bore yields 982 N push at 0.5 MPa; if your mechanism requires less force, the 40 mm bore offers 628 N, and if you need more power, the 63 mm bore provides 1559 N. Remember that a plain SE cylinder does not hold a load when air is exhausted or a valve is centered, so a BSE rod lock variant is required for fail-safe positioning. To retrofit an existing machine, match the 280 mm stroke, PT1/4 port, and ISO 15552 mounting interface. Because the stroke is 280 mm, the 20 mm rod and bearing are subject to bending under lateral loads; an external guide rail is recommended to prevent premature seal wear.
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 SE50AX280S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N push and 825 N pull force. At 0.7 MPa, push increases to 1374 N, with a maximum push of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE50AX280S is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint and can serve as a drop-in replacement for other ISO 15552 profile cylinders. The built-in magnet also allows direct integration with AirTAC CMSE and DMSE position sensors.
