Airtac SE125 Standard Cylinder SE125X222S
The AirTAC Airtac SE125 Standard Cylinder SE125X222S is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 222mm stroke, PT1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE125 Standard Cylinder SE125X222S
The AirTAC SE125X222S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a substantial 6136 N push force at 0.5 MPa. Its robust square extruded aluminum barrel omits external tie rods, yielding a flush, corrosion-resistant body that simplifies mounting and maximizes spatial efficiency on large machinery. Because the 222 mm stroke is non-standard, this specific unit is manufactured as a made-to-order configuration to meet exact machinery requirements.
This model includes a built-in magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic position sensors along its three-sided sensor grooves. The field-adjustable pneumatic cushioning at both ends is a true velocity-deceleration mechanism, not a fixed rubber bumper, allowing technicians to dial in end-of-stroke dampening for massive 125 mm payloads moving at up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X222S Is Used
Injection Mold Ejection
Provides the 6136 N push force required to eject large automotive plastic injection molds, utilizing its 222 mm stroke to clear the heavy tooling safely.
Palletizer Stopper Gate
Acts as a heavy-duty stop gate in high-speed palletizing cells, where the 125 mm bore absorbs substantial kinetic energy from incoming 1000 kg pallets.
Hydraulic Press Feeder
Pushes heavy steel billets into a hydraulic press, where the 222 mm stroke positions the material precisely before the main ram descends.
Is the Airtac SE125 Standard Cylinder SE125X222S the Right Cylinder?
Selecting this 125 mm bore is ideal when 80 mm (2513 N push @0.5 MPa) is insufficient for your heavy load, and you require maximum standard capacity before stepping up to larger custom pneumatics. If 1252 kgf at 1.0 MPa is overkill, stepping down to the 100 mm bore (3927 N push @0.5 MPa) saves space and air consumption. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, sharing standardized mounting accessories. To replicate this exact unit, specify: 125 mm bore, 222 mm stroke, PT1/2 port, basic mounting, and the -S magnet. Note that a plain SE cylinder does not hold its position or load when air is lost or the valve is centered—the piston drifts. For load-holding without live pressure, consider the BSE rod lock variant.
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 SE125 Standard Cylinder SE125X222S FAQ
At 0.5 MPa, it provides 6136 N push and 5734 pull force. At 0.7 MPa, push increases to 8590 N. The maximum push force is 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
No. The adjustable air cushion at both ends only decelerates the piston near the end of the stroke; it is not a locking brake. If your application requires the load to be held mechanically without live air pressure, you should use the BSE rod lock variant or an external pilot-operated check valve.
