About the Airtac SE125 Standard Cylinder SE125X25SFTC
The AirTAC SE125X25SFTC is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a substantial 6136 N push force at 0.5 MPa. It features a robust 125 mm bore and a 25 mm stroke, making it ideal for high-impact operations requiring immense power over short distances. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant profile that mounts flush in tight machinery spaces.
This configuration includes a built-in magnet for CMSE reed and DMSE electronic position sensors, ensuring precise end-of-stroke detection. The FTC center trunnion mounting provides pivotal articulation to accommodate lateral misalignment. Furthermore, the field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration, protecting the 32 mm hard-chrome rod from destructive impact loads during high-speed 30-500 mm/s cycles.

Where the Airtac SE125 Standard Cylinder SE125X25SFTC Is Used
Heavy Metal Stamping
Provides the 6136 N push force required to drive small stamping dies and form thick-gauge sheet metal components over the 25 mm stroke.
Injection Mold Ejection
Uses the FTC trunnion mount to pivot slightly while delivering rapid 30-500 mm/s ejection strokes to push dense plastic parts from heavy molds.
Automotive Component Crimping
Applies immense short-stroke clamping pressure to crimp heavy-duty hose fittings and electrical terminals in automated assembly lines.
Is the Airtac SE125 Standard Cylinder SE125X25SFTC the Right Cylinder?
Selecting the SE125X25SFTC is appropriate when your application demands maximum thrust, as it generates 6136 N of push at 0.5 MPa. If this overwhelming force risks damaging your payload, stepping down to the 100 mm bore yields a more moderate 3927 N push. Conversely, this 125 mm bore is the largest available in the SE series, so for extreme requirements beyond its 1252 kgf maximum at 1.0 MPa, you would need to explore twin-cylinder configurations. Because this is a standard double-acting cylinder, it will drift and drop if air pressure is lost; if your fixture must hold a load safely during an e-stop or pressure failure, pair it with a BSE rod lock variant. For ISO 15552 dimensional interchangeability, ensure you match the PT1/2 port, the FTC trunnion accessory, and the -S magnet requirement.
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 SE125X25SFTC FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, the SE125X25SFTC is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint and PT1/2 port locations of other ISO 15552 profile cylinders. The built-in -S magnet also works seamlessly with AirTAC CMSE reed and DMSE electronic sensors.
