About the Airtac SE125 Standard Cylinder SE125X180S
The AirTAC SE125X180S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a robust 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while freeing up valuable real estate in dense layouts.
Equipped with a built-in magnet (S option), this unit seamlessly integrates AirTAC CMSE reed and DMSE electronic sensors directly into the body grooves for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune the deceleration of the heavy 32 mm rod via a set screw, softening hard end stops during high-kinetic-energy cycles.

Where the Airtac SE125 Standard Cylinder SE125X180S Is Used
Stamping Press Ejection
Provides the intense 8590 N push force at 0.7 MPa required to knock heavy stamped metal panels out of progressive dies reliably.
Injection Mold Separation
Drives the separation of thick-walled industrial plastic injection molds, using its 180 mm stroke and 6136 N base push to break the vacuum grip on large parts.
Structural Beam Straightening
Applies concentrated lateral force to bend and align heavy structural steel tubing during fabrication, leveraging the massive 1252 kgf maximum output.
Is the Airtac SE125 Standard Cylinder SE125X180S the Right Cylinder?
Selecting the SE125X180S is appropriate when your application demands extreme thrust, but sizing requires careful context. If you need to step down to reduce physical size and air consumption, the neighboring 100 mm bore provides 3927 N push at 0.5 MPa. As the largest standard profile bore, there is no larger neighbor in this series, so for loads exceeding 1252 kgf at 1.0 MPa, you must evaluate a multi-cylinder mechanical arrangement. Because this is a plain double-acting cylinder, it cannot hold a load if air pressure drops or the valve centers; the piston will drift, so a BSE rod lock or external pilot-operated check valve is mandatory for fail-safe vertical holding.
For retrofitting, this model is dimensionally interchangeable per ISO 15552, meaning it serves as a drop-in replacement for other ISO 15552 cylinders without altering mounting footprints. It utilizes a PT1/2 port, a 32 mm rod with an M27x2 thread, and the standardized mounting accessory interface. While 180 mm is a standard stroke, the sheer mass of the 125 mm piston at high speeds requires verifying your rod-bearing bending limits.
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 SE125X180S FAQ
The SE125X180S generates a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operating speed range for this 125 mm bore cylinder is 30-500 mm/s.
