About the Airtac SE125 Standard Cylinder SE125X140S
The AirTAC SE125X140S is a double-acting single-rod profile cylinder built to the ISO 15552 / VDMA 24562 standard. It features a robust 125 mm bore and a 140 mm stroke, utilizing a PT1/2 port and a 32 mm hard-chrome plated rod with an M27x2 thread. Delivering 6136 N of push force at 0.5 MPa (up to 8590 N at 0.7 MPa), it is engineered for heavy-duty industrial motion.
The extruded aluminum barrel design omits external tie rods, presenting a clean, corrosion-resistant profile that mounts flush against machinery. Because this unit includes the -S magnet code, it is fully wired for AirTAC CMSE reed and DMSE electronic position sensing. Furthermore, the field-adjustable pneumatic cushioning at both stroke ends allows precise tuning to decelerate massive 1252 kgf peak loads smoothly.

Where the Airtac SE125 Standard Cylinder SE125X140S Is Used
Hydraulic Press Ejection
Ejects heavy formed metal panels from a 1000-ton hydraulic press, utilizing the 6136 N push force to break the part loose safely.
Injection Mold Clamping
Secures the rear half of a large plastic injection mold tool, relying on the 125 mm bore's massive 1252 kgf peak capacity.
Steel Plate Straightener
Applies localized bending pressure to flatten 8mm steel plates, using the 140 mm stroke to clear the workpiece during retraction.
Is the Airtac SE125 Standard Cylinder SE125X140S the Right Cylinder?
At 125 mm, this is the largest standard SE bore, so the only step-down option is the 100 mm cylinder, which yields 3927 N push at 0.5 MPa. If your application demands even more force than the SE125X140S provides, you must move outside the standard SE series. Keep in mind that a plain double-acting cylinder relies on live air pressure to hold a load; if your valve centers or air supply drops, the piston will drift. For critical hold-down applications, consider the BSE rod lock variant.
For a drop-in retrofit, match the 125 mm bore, 140 mm stroke, PT1/2 port, and your required mounting accessory. The 32 mm rod and M27x2 thread provide high rigidity, but for any stroke at 300 mm or beyond, the unsupported load increases rod-bearing bending moments, making an external guide rail highly recommended.
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 SE125X140S 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 operating speed range is 30-500 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 profile cylinders. Because it carries the -S magnet option, it supports AirTAC CMSE reed switches and DMSE electronic sensors for precise end-of-stroke detection.
