About the Airtac SE125 Standard Cylinder SE125X150SN
The AirTAC SE125X150SN 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. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while surviving demanding washdown environments.
Equipped with a magnetic piston for non-contact position detection, this unit seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors housed within the triple-sided sensor grooves. The NBR seal provides reliable operation across standard temperature ranges, while the field-adjustable pneumatic cushioning at both ends allows technicians to dial in end-of-stroke deceleration, smoothly braking a 1252 kgf maximum load without mechanical shock.

Where the Airtac SE125 Standard Cylinder SE125X150SN Is Used
Heavy Press Forming
Drives large metal stamping and bending presses, utilizing the 6136 N push force to deform thick sheet metal components that smaller 100 mm bores cannot handle.
Injection Mold Ejection
Ejects dense plastic or aluminum castings from heavy industrial molds, relying on the 150 mm stroke and NBR seals to withstand high ambient shop heat.
Pallet Lift Gates
Actuates heavy-duty lift gates and industrial pallet stops, where the built-in magnet enables CMSE sensors to confirm gate positioning under 1252 kgf loads.
Is the Airtac SE125 Standard Cylinder SE125X150SN the Right Cylinder?
Selecting the SE125X150SN is appropriate when your application demands extreme linear thrust, as stepping down to the 100 mm bore drops your 0.5 MPa push force to 3927 N. As the largest bore in the standard SE lineup, it has no upward neighbor, making it the ultimate choice for maximum pneumatic output within this series. If a machine failure requires an urgent retrofit, this model is dimensionally interchangeable per ISO 15552, meaning it serves as a direct drop-in replacement for other ISO 15552 cylinders without altering your existing mounting hardware.
Because this is a standard double-acting cylinder, the piston will drift if air pressure is lost or the valve is centered; it cannot hold a vertical load safely without live pressure. For gravity-defying holding requirements, pair this cylinder with an external pilot-operated check valve or transition to the BSE rod-lock variant. Furthermore, while the robust 32 mm rod and M27x2 thread handle high axial stress, any stroke exceeding 300 mm on larger bores necessitates an external guide to prevent rod-bearing bending under heavy 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.
