About the Airtac SE50 Standard Cylinder SE50AX15
The AirTAC SE50AX15 is a double-acting, single-rod ISO 15552 profile cylinder engineered for short-stroke automation. It delivers a robust 982 N push force at 0.5 MPa, utilizing a 50 mm bore and a 15 mm stroke. Because this SKU uses the A code rod material, it features a SUS420J2 stainless steel piston rod specifically chosen for corrosive or washdown environments.
The extruded aluminum barrel design omits external tie rods, yielding a compact, flush-mounting body that is dimensionally interchangeable with other ISO 15552 cylinders. Field-adjustable pneumatic cushioning at both ends allows you to fine-tune end-of-stroke deceleration, protecting machinery from hard impacts. Note that this specific SKU lacks the S magnet, meaning it is not equipped out-of-the-box for AirTAC CMSE or DMSE position sensing.

Where the Airtac SE50 Standard Cylinder SE50AX15 Is Used
Pouch Sealing Clamp
Provides the precise 982 N clamping force needed to hold vertical form-fill-seal pouch jaws shut during heat sealing, while the SUS420J2 rod shrugs off washdown.
Lab Sample Ejector
Executes short 15 mm retraction strokes to push tested specimens out of analytical equipment, where the compact tie-rod-free profile fits tight lab enclosures.
CNC Chuck Actuator
Drives a short-stroke secondary clamping mechanism on a CNC lathe, using adjustable cushioning to soften the end stop and protect the spindle bearings.
Is the Airtac SE50 Standard Cylinder SE50AX15 the Right Cylinder?
This 50 mm bore provides 982 N of push force at 0.5 MPa. If your application requires less force, the 40 mm bore offers 628 N, or you can step up to the 63 mm bore which provides 1559 N for heavier loads. Keep in mind that a standard double-acting cylinder relies on live air pressure to hold its position; if air is lost, the piston drifts. For applications needing true position holding without continuous pressure, consider the BSE rod lock variant. For a drop-in ISO 15552 replacement, match the 50 mm bore, 15 mm stroke, PT1/4 port, and basic mounting interface.
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 SE50AX15 FAQ
This 50 mm bore cylinder features a PT1/4 port and generates 982 N of push force and 825 N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 1374 N, and it reaches a maximum push of 200 kgf at 1.0 MPa.
No, this specific SKU lacks the S option, meaning it does not have a built-in piston magnet. To use CMSE reed or DMSE electronic sensors, you would need an SE50 model specified with the S magnet code.
