About the Airtac SE125 Standard Cylinder SE125X35S
The AirTAC SE125X35S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic actuation. It generates a substantial 6136 N of push force at 0.5 MPa, making it well-suited for high-thrust operations requiring a short 35 mm stroke. The robust 32 mm hard-chrome rod and M27x2 thread provide exceptional resistance against side-loading stresses.
Built with a square extruded aluminum barrel that eliminates external tie rods, this cylinder offers a flush, corrosion-resistant exterior that simplifies mounting and cleanup. The integrated magnet (-S) enables seamless position detection using AirTAC CMSE reed or DMSE electronic sensors. Furthermore, the field-adjustable air cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration, preventing harsh impacts even under heavy dynamic loads.

Where the Airtac SE125 Standard Cylinder SE125X35S Is Used
Stamping Press Ejection
Provides the intense 6136 N push force required to knock heavy stamped metal panels out of progressive dies, utilizing the short 35 mm stroke for rapid cycling.
Injection Mold Separation
Delivers robust clamping and separation force for large injection molding halves, leveraging the 32 mm rod to withstand initial mechanical shock during part ejection.
Heavy Gauge Metal Bending
Acts as a primary press cylinder for bending thick-walled steel tubing, where the adjustable air cushions absorb the severe kinetic energy generated at stroke end.
Is the Airtac SE125 Standard Cylinder SE125X35S the Right Cylinder?
Selecting the SE125X35S is optimal when your application demands maximum thrust within a compact stroke. If you need to scale down, the neighboring 100 mm bore provides 3927 N of push at 0.5 MPa; stepping up to this 125 mm bore yields 6136 N, while it remains the largest standard option in the SE range. As a true ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standard mounting accessories like FA flanges or LB foot brackets. The PT1/2 port ensures high airflow to support its 30-500 mm/s speed range.
Because the SE is a double-acting cylinder, it will drift if air pressure is lost or the valve is centered; it cannot hold a load statically without live pressure. For applications requiring physical load holding, consider the BSE rod-lock variant. Given the high thrust and heavy moving mass, always verify that your external guiding mechanism can absorb any potential side loads.
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 SE125X35S FAQ
At 0.5 MPa, this 125 mm bore cylinder outputs 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N. The maximum push force is 1252 kgf at 1.0 MPa, and its operating speed ranges from 30-500 mm/s.
Yes. The SE125X35S is a standard ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 cylinders. You can use your existing mounting hardware and drop it directly into the same footprint. The -S magnet also allows you to mount AirTAC CMSE or DMSE sensors directly into the barrel grooves.
