About the Airtac SE50 Standard Cylinder SE50AX260S
The AirTAC SE50AX260S is a double-acting single-rod ISO 15552 profile cylinder engineered for 260 mm stroke applications. It features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance in washdown environments, delivering a robust 982 N push force at 0.5 MPa. The square extruded aluminum barrel eliminates external tie rods, yielding a compact footprint that mounts flush against machine frames.
Equipped with a built-in magnet (code S), this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection. Field-adjustable air cushions at both ends allow technicians to tune deceleration, softening hard end stops during high-speed cycling without relying on fixed rubber bumpers.

Where the Airtac SE50 Standard Cylinder SE50AX260S Is Used
Pouch Forming Jaws
Drives the vertical sealing jaws on continuous motion pouch machines, using its 982 N thrust and 260 mm travel to fold and seal packaging film reliably.
Pallet Diverters
Actuates routing pop-up arms on flat-belt conveyors to divert heavy pallets, utilizing the SUS420J2 stainless rod to withstand humid washdown zones.
Lab Sample Indexing
Pushes sample carousels in automated clinical analyzers, where the built-in magnet triggers DMSE electronic sensors for precise 260 mm transfer strokes.
Is the Airtac SE50 Standard Cylinder SE50AX260S the Right Cylinder?
Selecting this 50 mm bore makes sense when you need 982 N push at 0.5 MPa but want to avoid the bulk of a 63 mm cylinder (which provides 1559 N). If your load is lighter, stepping down to a 40 mm bore yields 628 N and saves space. Because this model spans 260 mm, the unsupported piston rod is subject to bending under lateral loads; always pair it with an external guide rail to prevent rod-bearing wear. Remember that standard air cushions only decelerate the piston near stroke end—they do not hold the load. If air pressure drops, the rod will drift; use a BSE rod lock for fail-safe holding.
As a true ISO 15552 profile cylinder, the SE50AX260S is dimensionally interchangeable with other ISO 15552 cylinders, making it a seamless retrofit. It uses a PT1/4 port and a 20 mm rod with an M16x1.5 thread.
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 SE50AX260S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum push force is 200 kgf when operated at the 1.0 MPa pressure limit.
Yes. The SE50AX260S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders using the same mounting hardware and PT1/4 port locations without modifying the machine frame.
