About the Airtac SE125 Standard Cylinder SE125X290S
The AirTAC SE125X290S is a double-acting single-rod profile cylinder built to the ISO 15552 standard. It features a robust 125 mm bore and a 290 mm stroke, generating a substantial 6136 N push force at 0.5 MPa. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal components.
Equipped with a built-in magnet (-S), this unit seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. Field-adjustable air cushioning at both ends allows technicians to tune the deceleration of heavy 1252 kgf loads, softening hard end stops without relying on fixed rubber bumpers.

Where the Airtac SE125 Standard Cylinder SE125X290S Is Used
Stamping Press Ejection
Provides the heavy 6136 N push force required to knock thick steel blanks out of progressive die stamping presses, utilizing the 290 mm stroke to clear the lower die shoe entirely.
Injection Mold Separation
Rips large, vacuum-gripped plastic automotive bumpers from injection mold cores, where the high 5734 N pull force overcomes deep-draft friction during automated unloading.
Pallet Stop Gate
Acts as a heavy-duty physical stop gate on high-mass roller conveyors, raising a 290 mm barrier to halt fully loaded 1000 kg pallets before they reach the wrapping station.
Is the Airtac SE125 Standard Cylinder SE125X290S the Right Cylinder?
Selecting the SE125X290S is appropriate when your application requires massive thrust, but sizing both ways is critical. If 6136 N push at 0.5 MPa exceeds your requirement, stepping down to the 100 mm bore yields 3927 N, saving space and air consumption. Conversely, if you need to push beyond the 125 mm bore's 8590 N capacity at 0.7 MPa, you will need to explore twin-cylinder setups or larger non-standard actuators, as 125 mm is the largest standard SE bore.
Because this model features a 290 mm stroke, the 32 mm rod and internal bearing face bending moments under high side loads; always support the load with an external guide to prevent premature seal wear. Note that the adjustable air cushion only decelerates the piston near stroke end—it does not lock or hold the load. If air pressure drops, the cylinder drifts, so deploy a BSE rod lock for fail-safe position holding. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders, utilizing standard PT1/2 ports and an M27x2 rod thread.
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 SE125X290S FAQ
At 0.5 MPa, this 125 mm bore cylinder delivers 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N. The maximum push capacity is 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, the SE125X290S is dimensionally interchangeable per ISO 15552, meaning it shares the exact same mounting interface, PT1/2 port size, and M27x2 rod thread as other standard profile cylinders, allowing for a direct drop-in retrofit.
