Airtac SE125 Standard Cylinder SE125X60
The AirTAC Airtac SE125 Standard Cylinder SE125X60 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 60mm 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 SE125X60
The AirTAC SE125X60 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic motion. Operating at 0.5 MPa, it generates a substantial 6136 N push force and 5734 N pull force, making it well-suited for demanding high-mass automation. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant profile that mounts flush against machine frames while exposing standardized ISO 15552 interface dimensions for universal hardware matching.
This specific configuration features a 125 mm bore, a 60 mm stroke, and a PT1/2 port. Because this SKU lacks the -S magnet option, it does not support AirTAC CMSE or DMSE position sensing out of the box. Field-adjustable air cushioning at both stroke ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard mechanical stops for moving masses rather than acting as a locking mechanism.

Where the Airtac SE125 Standard Cylinder SE125X60 Is Used
Injection Mold Clamping
Provides the heavy 6136 N push force required to secure large injection mold halves during plastic part curing, utilizing the 60 mm stroke for rapid open-close cycles.
Metal Stamping Ejection
Ejects heavy stamped sheet metal blanks from progressive dies, where the adjustable end cushions soften the retraction stop for the heavy 32 mm rod assembly.
Hydraulic Press Leveling
Actuates leveling beds beneath heavy hydraulic presses, moving bulky sub-assemblies into precise alignment using the robust ISO 15552 profile body.
Is the Airtac SE125 Standard Cylinder SE125X60 the Right Cylinder?
When sizing this 125 mm bore model, verify if the 6136 N push at 0.5 MPa exceeds your actual load requirement. Stepping down to the 100 mm bore reduces the footprint and yields 3927 N of push force at 0.5 MPa. As the largest standard bore in the SE range, there is no larger option available, so if 6136 N is insufficient, you must either increase air pressure toward the 1.0 MPa maximum (yielding 1252 kgf) or employ a larger bore from a different series. To guarantee a true drop-in retrofit, match the 125 mm bore, 60 mm stroke, PT1/2 port, and the specific mounting accessory (such as FA flange or TC trunnion). Note that a plain SE cylinder will drift if air pressure is lost or the valve centers, so it cannot hold vertical loads safely without adding a BSE rod lock or external pilot-operated check valve.
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 SE125X60 FAQ
At 0.5 MPa, the SE125X60 delivers 6136 N of push force and 5734 N of pull force. 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 for this 125 mm bore is 30-500 mm/s.
Yes, it is dimensionally interchangeable with any ISO 15552 cylinder, allowing you to reuse existing mounting brackets and rod-end joints. However, it does not hold position when air is lost; the field-adjustable air cushions only decelerate the piston near stroke end rather than locking it. For load-holding, consider the BSE rod lock variant.
