About the Airtac SE50 Standard Cylinder SE50AX25
The AirTAC SE50AX25 is a double-acting, single-rod ISO 15552 profile cylinder engineered for short-stroke actuation. It delivers 982 N of push force and 825 N of pull force at 0.5 MPa, utilizing a 20 mm rod with an M16x1.5 thread. Because this SKU uses the A code rod material, it features a SUS420J2 stainless steel rod engineered specifically for corrosive environments and washdown duty.
Unlike traditional tie-rod bodies, its extruded aluminum barrel lacks external tie rods, yielding a compact, flush-mounting profile that resists debris buildup. The cylinder incorporates field-adjustable air cushions at both ends to tune end-of-stroke deceleration, though it relies on live air pressure to hold position and will drift if air is lost.

Where the Airtac SE50 Standard Cylinder SE50AX25 Is Used
Flow Wrapper End-Seal
Drives the 25 mm end-seal jaw motion on continuous motion flow wrappers, using the 982 N push force to cleanly crimp packaging film without stalling.
Bottle Rinser Gripper
Actuates the gripper arms on rotary bottle rinsing stations, where the SUS420J2 stainless rod withstands splashing from caustic wash fluids.
PCB Router Clamp
Secures printed circuit boards during routing operations, providing stable clamping within a short 25 mm travel envelope.
Is the Airtac SE50 Standard Cylinder SE50AX25 the Right Cylinder?
If 982 N of push at 0.5 MPa is too much for your payload, stepping down to the 40 mm bore drops the push force to 628 N. Conversely, if you need more authority, stepping up to the 63 mm bore increases the 0.5 MPa push to 1559 N. As a standard ISO 15552 profile cylinder, this 50 mm bore with a 25 mm stroke, PT1/4 port, and basic mounting is dimensionally interchangeable with other ISO 15552 cylinders, making it a direct retrofit. Note that this specific SKU lacks the -S magnet, so it cannot host CMSE or DMSE position sensors without changing the configuration.
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 SE50AX25 FAQ
At 0.5 MPa, the SE50AX25 generates 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force is 1374 N, with a maximum push capacity of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the SE50AX25 is a double-acting cylinder that relies on live air pressure to maintain position; it will drift if air is exhausted. The adjustable air cushions at both ends only decelerate the piston near the stroke ends and do not function as a locking brake.
