About the Airtac SE50 Standard Cylinder SE50AX115S
The AirTAC SE50AX115S is a double-acting, single-rod profile cylinder built to the ISO 15552 / VDMA 24562 dimensional standard. It delivers a 982 N push force at 0.5 MPa and utilizes a 115 mm stroke. This model features a SUS420J2 stainless steel piston rod (code A), making it highly suitable for corrosive or washdown environments where a standard carbon steel rod would fail prematurely.
The extruded aluminum barrel design omits external tie rods, yielding a smooth, compact profile that is easy to mount flush against machine frames. It includes a built-in magnet (code S) for position sensing and integrates field-adjustable air cushioning at both ends to decelerate the piston near the stroke limits, reducing end-cap impact wear.

Where the Airtac SE50 Standard Cylinder SE50AX115S Is Used
Flow Wrapper Carton Folding
Drives the side folding flaps on a continuous motion flow wrapper, using the 115 mm stroke and 982 N push to cleanly tuck carton ends before the sealing jaw.
Bottle Rinser Gripper
Actuates the neck gripper mechanism on a rotary bottle rinsing station, where the SUS420J2 stainless rod withstands constant moisture and chemical spray.
Spiral Diverter Gate
Pivots the sorting flap on a spiral gravity conveyor, relying on the adjustable pneumatic cushion to soften the hard end stops during rapid cycling.
Is the Airtac SE50 Standard Cylinder SE50AX115S the Right Cylinder?
In the 50 mm bore class, this cylinder provides 982 N push and 825 N pull at 0.5 MPa. If your application requires less force, stepping down to the 40 mm bore yields a 628 N push, while stepping up to the 63 mm bore increases the push capacity to 1559 N. Because this is a double-acting air cylinder, it will drift and cannot hold a load if air pressure is lost or the valve is centered; for positive holding, consider the BSE rod-lock variant or an external pilot-operated check valve.
As a true ISO 15552 cylinder, the SE50AX115S is dimensionally interchangeable with other ISO 15552 profile cylinders, allowing you to retrofit existing machinery without changing the mounting footprint or hardware. The PT1/4 port and M16x1.5 rod thread match the standard 50 mm bore specifications. The included -S magnet directly supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection.
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 SE50AX115S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, the push force is 1374 N. The maximum push force is 200 kgf at 1.0 MPa. The operating speed range is 30-800 mm/s.
Yes. The SE50AX115S is dimensionally interchangeable per ISO 15552, meaning it shares the exact same mounting interface, center distances, and PT1/4 port locations as other standard profile cylinders, allowing for a direct drop-in retrofit.
