About the Airtac SE125 Standard Cylinder SE125X15S
The AirTAC SE125X15S is a double-acting single-rod ISO 15552 profile cylinder engineered for extreme force in tight stroke envelopes. Operating at 0.5 MPa, it generates 6136 N of push force and 5734 N of pull force, peaking at a massive 1252 kgf at 1.0 MPa. The 15 mm stroke makes it highly effective for short, powerful clamping or pressing operations. Its square extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting body that naturally resists corrosion and simplifies fixture integration.
Equipped with a built-in magnet (S option), this unit directly supports AirTAC CMSE reed and DMSE electronic position sensors for precise end-of-stroke verification. The field-adjustable pneumatic cushioning at both ends can be tuned with a screw to decelerate heavy 125 mm payloads smoothly, preventing harsh mechanical impacts. With a robust Ø32 mm rod and M27x2 thread, it handles substantial side loads, while the PT1/2 port ensures high airflow to maintain the 30-500 mm/s speed range.

Where the Airtac SE125 Standard Cylinder SE125X15S Is Used
Heavy-Duty Stamping Press
Leverages the 6136 N push force at 0.5 MPa to execute short 15 mm strokes for deforming or marking thick metal plates in automated fabrication cells.
Injection Mold Ejection
Uses the integrated magnet with DMSE sensors to confirm a crisp 15 mm retraction, safely ejecting dense molded parts weighing hundreds of kilograms without collision.
Industrial Riveting Head
Applies the massive 1252 kgf peak capability to squeeze and form large structural rivets in heavy machinery assembly, relying on adjustable cushioning to soften the abrupt end stop.
Is the Airtac SE125 Standard Cylinder SE125X15S the Right Cylinder?
Selecting the SE125X15S is optimal when an application demands maximum thrust within a minimal 15 mm travel. If you need to step down to reduce physical size and air consumption, the neighboring 100 mm bore provides 3927 N of push at 0.5 MPa. As the largest standard ISO 15552 bore in the AirTAC range, stepping up beyond 125 mm requires custom solutions, making this the peak choice for standard high-force tasks. Because this is a double-acting cylinder, it will drift if air pressure is lost or the valve is centered; applications requiring fail-safe load holding should utilize a BSE rod lock variant or an external pilot-operated check valve.
For retrofitting, this model is dimensionally interchangeable per ISO 15552, matching the mounting footprint of other standard 125 mm profile cylinders. Ensure your setup specifies a 125 mm bore, 15 mm stroke, PT1/2 ports, and the -S magnet for sensor compatibility. Given the short 15 mm stroke, side-load bending on the rod bearing is negligible, but always ensure axial alignment to prevent premature seal wear during high-force pressing.

- ✓ 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 SE125X15S FAQ
The SE125X15S delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force reaches 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range for this 125 mm bore cylinder is 30-500 mm/s.
