About the Airtac SE125 Standard Cylinder SE125X195
The AirTAC SE125X195 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a substantial 6136 N push force at 0.5 MPa. Its robust 125 mm bore and 195 mm stroke make it a powerhouse for moving substantial masses in demanding industrial environments.
This unit features a square extruded aluminum barrel without external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames. The field-adjustable air cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration via a setscrew, preventing impact damage during high-speed 30-500 mm/s operations. As this SKU lacks the -S magnet, it does not support integrated CMSE or DMSE position sensing.

Where the Airtac SE125 Standard Cylinder SE125X195 Is Used
Injection Mold Clamping
Delivers 8590 N of push force at 0.7 MPa to secure heavy injection mold halves during the injection cycle, utilizing the 195 mm stroke to clear the mold area for part extraction.
Stamping Press Feed
Moves thick steel blanks into a mechanical press, relying on the 125 mm bore's 6136 N force at 0.5 MPa to overcome friction and position the material accurately.
Palletizer Ejection
Pushes completed 1000 kg pallet loads onto a discharge roller conveyor, where the adjustable end cushions absorb kinetic energy to prevent load tipping at cycle end.
Is the Airtac SE125 Standard Cylinder SE125X195 the Right Cylinder?
In the 125 mm class, there is no larger standard SE bore, so if you need less force you would step down to the 100 mm bore, which provides 3927 N push at 0.5 MPa. Because a plain double-acting cylinder relies on continuous air pressure to maintain its position, the SE125X195 will drift if supply is lost; for fail-safe load holding, consider the BSE rod-lock variant or an external pilot-operated check valve. Being dimensionally interchangeable per ISO 15552, this unit serves as a direct drop-in replacement for other ISO 15552 profile cylinders, utilizing the same mounting hardware and PT1/2 port.
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 SE125X195 FAQ
The SE125X195 generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, and reaches a maximum push capacity of 1252 kgf at 1.0 MPa operating pressure.
This specific SKU lacks the -S magnet, so it cannot host CMSE or DMSE electronic or reed sensors without modification. It uses an ISO 15552 mounting interface with a PT1/2 port and a M27x2 rod thread, allowing it to drop into existing ISO 15552 profile cylinder setups.
