Airtac SE125 Standard Cylinder SE125X15
The AirTAC Airtac SE125 Standard Cylinder SE125X15 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 15mm 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 SE125X15
The AirTAC SE125X15 is a double-acting single-rod ISO 15552 profile cylinder engineered for extreme force in a very short stroke. Operating at 0.5 MPa, it generates 6136 N of push force and 5734 N of pull force, scaling up to a maximum of 1252 kgf at 1.0 MPa. The extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This specific SKU lacks a built-in magnet, meaning it ships without position sensing out of the box. To decelerate heavy payloads at the 15 mm stroke end, field-adjustable pneumatic cushioning at both ends allows technicians to dial in the exact damping resistance via a setscrew, preventing hard mechanical impacts.

Where the Airtac SE125 Standard Cylinder SE125X15 Is Used
Heavy-Duty Stamping Press
Drives a short-stroke top tool to punch thick gauge steel, utilizing the 6136 N push force to shear material cleanly within a 15 mm travel window.
Injection Mold Clamping
Secures heavy mold halves together under high pressure, relying on the 125 mm bore and 5734 N pull force to resist cavity expansion forces.
Hydraulic Crimping Station
Compresses large diameter steel cable terminals, applying up to 1252 kgf of force at 1.0 MPa to deform thick-walled copper sleeves in a single rapid stroke.
Is the Airtac SE125 Standard Cylinder SE125X15 the Right Cylinder?
Selecting the SE125X15 is ideal when a machine requires massive clamping or holding power within a severely constrained 15 mm travel distance. If you do not need 6136 N of push at 0.5 MPa, stepping down to the 100 mm bore yields 3927 N, saving space and air consumption. Because this is a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing identical mounting interface dimensions and port sizes (PT1/2). Remember that a plain double-acting cylinder drifts when air is lost; if your clamping fixture must hold a load safely without live pressure, integrate an external rod lock or a 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 SE125X15 FAQ
The SE125X15 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 an absolute maximum push of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
No, the SE125X15 is a standard double-acting cylinder and will drift if air is lost or the valve is centered. The adjustable air cushion at both ends only decelerates the piston near the stroke end and does not function as a mechanical lock or brake.
