About the Airtac SE125 Standard Cylinder SE125X10
The AirTAC SE125X10 is a double-acting single-rod ISO 15552 profile cylinder engineered for high-impact short-stroke tasks, delivering a robust 6136 N push force at 0.5 MPa. Its extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. This design simplifies integration while maintaining the rigorous ISO 15552 footprint.
Because this specific SKU lacks the -S magnet suffix, it does not support direct CMSE or DMSE position sensing without modification. The 40 mm adjustable air cushion at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when moving heavy loads. Operating at 30-500 mm/s, it leverages a 32 mm rod and M27x2 thread to handle substantial thrust.

Where the Airtac SE125 Standard Cylinder SE125X10 Is Used
Heavy Press Pinching
Drives a short-stroke wedge in a heavy-duty metal stamping press, utilizing the 6136 N push force to clamp thick steel blanks securely before the press cycles.
Injection Mold Ejector
Acts as a primary knock-out pin actuator for large injection molding machines, where the 10 mm stroke rapidly breaks the vacuum on bulky plastic parts.
Log Debarker Stop
Functions as a high-force mechanical stop in timber processing, using its 1252 kgf maximum thrust to halt and brace heavy logs on a conveyor before debarking.
Is the Airtac SE125 Standard Cylinder SE125X10 the Right Cylinder?
Selecting the SE125X10 is ideal when a brief 10 mm motion requires massive thrust, such as pinching or gripping heavy stock. If you need to step down, the 100 mm bore provides 3927 N push at 0.5 MPa; stepping up is not possible as 125 mm is the largest standard SE bore. As a double-acting cylinder, it will drift if air pressure is lost or the valve centers, so add a BSE rod lock for fail-safe load holding.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders. It uses a PT1/2 port and accepts standard mounting accessories like TC or LB brackets without requiring custom hardware.
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 SE125X10 FAQ
The SE125X10 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 increases to 8590 N. The maximum push force is 1252 kgf when operated at the 1.0 MPa pressure limit.
This specific SKU lacks the built-in magnet required for CMSE or DMSE sensors. Dimensionally, it is an ISO 15552 profile cylinder, making it a drop-in replacement for other ISO 15552 cylinders using standard mounting hardware, without claiming exact brand equivalence.
