About the Airtac SE125 Standard Cylinder SE125X180
The AirTAC SE125X180 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 omits external tie rods entirely, yielding a flush, corrosion-resistant body that simplifies mounting and reduces machine footprint.
This 125 mm bore unit features a 32 mm piston rod and a PT1/2 port. Because this specific SKU lacks the built-in magnet suffix, it does not support direct position sensing without modification. Field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration precisely, protecting heavy payloads from impact shocks.

Where the Airtac SE125 Standard Cylinder SE125X180 Is Used
Injection Mold Clamping
Provides the 6136 N push force required to secure heavy injection mold halves during high-pressure plastic injection cycles.
Hydraulic Press Ejection
Utilizes its 180 mm stroke to eject dense formed parts from hydraulic presses, absorbing kinetic energy via adjustable cushions.
Pallet Stopper Actuation
Acts as a heavy-duty stopper mechanism on automated pallet conveyors, relying on the 125 mm bore's 1252 kgf max thrust to halt heavy loads.
Is the Airtac SE125 Standard Cylinder SE125X180 the Right Cylinder?
Selecting the SE125X180 makes sense when your application demands up to 1252 kgf of maximum thrust at 1.0 MPa. If you need slightly less force, stepping down to the 100 mm bore yields 3927 N push at 0.5 MPa; however, the 125 mm bore is the largest standard AirTAC SE size, providing maximum output with no larger neighbour to step up to.
This cylinder uses a PT1/2 port and standard ISO 15552 mounting accessories. Remember that a plain double-acting cylinder drifts when air pressure is lost or exhausted—the adjustable air cushion only decelerates the piston near stroke end and cannot hold a load in place; for position holding, 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 SE125X180 FAQ
At 0.5 MPa, the SE125X180 delivers 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 when operated at the 1.0 MPa pressure limit.
Yes, it is dimensionally interchangeable per ISO 15552 standards, allowing it to drop into existing footprints using standard mounting hardware. However, it cannot hold a load without air pressure; the adjustable cushion only decelerates motion near stroke ends and does not function as a brake.
