About the Airtac SE125 Standard Cylinder SE125X75S
The AirTAC SE125X75S 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 125 mm bore and 75 mm stroke make it ideal for high-impact industrial tasks. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while preventing debris buildup.
This unit includes a built-in magnet (-S) enabling precise end-position detection with AirTAC CMSE reed or DMSE electronic sensors. The field-adjustable air cushion at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard stops for heavy 125 mm payloads traveling up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X75S Is Used
Stamping Press Ejection
Uses the 6136 N push force to knock heavy stamped metal panels out of progressive dies quickly and reliably.
Palletizer Flap Folding
Leverages the 75 mm stroke and 125 mm bore power to fold and secure thick cardboard flaps on bulk shipping pallets.
Injection Mold Separation
Provides the high pull force required to break heavy plastic injection molds apart for automated parts extraction.
Is the Airtac SE125 Standard Cylinder SE125X75S the Right Cylinder?
Selecting the SE125X75S is appropriate when your mechanism requires extreme force, such as 6136 N push at 0.5 MPa or 8590 N at 0.7 MPa. If this overpowers your application, stepping down to the 100 mm bore yields 3927 N push at 0.5 MPa; as the largest standard AirTAC profile bore, there is no larger up-step within the SE range. Being a true ISO 15552 cylinder, it offers a drop-in dimensional replacement for other ISO 15552 profile cylinders, sharing standardized mounting hardware and a PT1/2 port. Remember that a plain SE does not hold position or load when air is lost—use a BSE rod lock for fail-safe holding.
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 SE125X75S FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, the push force reaches 8590 N. The maximum push force is 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, the SE125X75S is dimensionally interchangeable per ISO 15552 standards, meaning it serves as a drop-in replacement for other ISO 15552 profile cylinders. The built-in magnet also works seamlessly with AirTAC CMSE and DMSE sensors.
