About the Airtac SE50 Standard Cylinder SE50AX50SFTC
The AirTAC SE50AX50SFTC is a double-acting single-rod ISO 15552 profile cylinder engineered for precise short-stroke actuation. It delivers a push force of 982 N at 0.5 MPa, utilizing a 50mm bore and a 50mm stroke. The SUS420J2 stainless steel rod provides enhanced corrosion resistance, making it well-suited for washdown environments where standard carbon steel rods would degrade.
This model features a square extruded aluminum barrel without external tie rods, yielding a compact footprint that mounts flush against machine frames. Integrated sensor grooves on three sides of the body accept CMSE reed or DMSE electronic switches, leveraging the built-in magnet for exact position detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration, preventing harsh impacts during high-speed cycling.

Where the Airtac SE50 Standard Cylinder SE50AX50SFTC Is Used
Pouch Sealing Press
Drives the upper sealing jaw on continuous flow wrappers, using the 982 N push force to maintain consistent crimp pressure across packaging films in damp environments.
Pallet Diverter Gate
Actuates a routing flap on a sortation line, relying on the FTC center trunnion to pivot smoothly and the SUS420J2 rod to resist ambient humidity.
Lab Dispense Valve
Opens and closes a precision fluid nozzle for reagent bottling, utilizing the built-in magnet to trigger DMSE electronic sensors for exact dosing cycles.
Is the Airtac SE50 Standard Cylinder SE50AX50SFTC the Right Cylinder?
Selecting this 50mm bore cylinder makes sense when your application requires roughly 1000 N of push force at 0.5 MPa. If you need to step down to lighten the payload and save space, the 40mm bore offers 628 N of push at 0.5 MPa. Conversely, if your load demands more authority, stepping up to the 63mm bore yields 1559 N at 0.5 MPa. Because this configuration uses the FTC center trunnion mounting accessory, it accommodates pivoting loads smoothly.
The 50mm stroke keeps the rod unsupported length short, minimizing side-load bending on the M16x1.5 rod thread and internal bearing. However, a plain SE cylinder does not hold its position or lock a load when air pressure is lost or the valve is centered; the piston will drift. If your fixture requires true mechanical holding power without live pressure, consider the BSE rod lock variant. For dimensionally interchangeable per ISO 15552 retrofits, match the 50mm bore, 50mm stroke, PT1/4 port, FTC mount, and -S magnet specification.
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 SE50AX50SFTC FAQ
At 0.5 MPa, this 50mm 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, with a maximum push capacity of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
Yes, the SE series is dimensionally interchangeable per ISO 15552. You can use this as a drop-in replacement for other ISO 15552 profile cylinders by matching the 50mm bore, 50mm stroke, PT1/4 port, and FTC mounting dimensions. The adjustable air cushions can then be tuned to match your existing machine timing.
