About the Airtac SE125 Standard Cylinder SE125X175S
The AirTAC SE125X175S 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 completely flush exterior that resists corrosion and simplifies direct mounting against machine frames.
Equipped with a built-in magnet (-S), this unit seamlessly integrates with AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends utilizes a 40 mm cushion length to decelerate the heavy 125 mm piston smoothly, allowing you to tune out harsh end-stop impacts at operating speeds up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X175S Is Used
Automotive Stamping Press Ejection
Leveraging 6136 N of push force, this cylinder reliably ejects heavy stamped metal body panels from a 400-ton press bed within its 175 mm stroke.
Structural Beam Straightening
Applies up to 1252 kgf of clamping pressure at 1.0 MPa to bend and align heavy structural steel I-beams during fabrication jigs.
Bulk Pallet Compaction
Uses the adjustable 40 mm cushioning to smoothly decelerate the 32 mm rod while compacting dense industrial corrugated packaging materials at high cyclic rates.
Is the Airtac SE125 Standard Cylinder SE125X175S the Right Cylinder?
Selecting this 125 mm bore provides maximum standard thrust, yielding 6136 N of push and 5734 N of pull at 0.5 MPa. If your application demands less force, stepping down to the 100 mm bore reduces the push output to 3927 N, while this SE125X175S represents the top tier for raw power. Because it is dimensionally interchangeable per ISO 15552, it serves as a direct drop-in replacement for other ISO 15552 cylinders, sharing standardized mounting hardware like TC center trunnions or CA clevises. To match your exact build, confirm the 175 mm stroke, PT1/2 port, and M27x2 rod thread. Note that a plain SE cylinder will drift if air pressure is lost; for position holding without live pressure, consider the BSE rod lock variant.
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 SE125X175S FAQ
This 125 mm bore cylinder provides 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, and a maximum push of 1252 kgf at 1.0 MPa. Its operating speed ranges from 30-500 mm/s.
No, the standard SE cylinder drifts when air is exhausted, and the adjustable air cushion only decelerates the piston near stroke end, it does not lock the rod. For secure load holding without live pressure, use the AirTAC BSE rod lock variant.
