About the Airtac SE125 Standard Cylinder SE125X1100
The AirTAC SE125X1100 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty linear motion. Operating at 0.5 MPa, it generates 6136 N of push force and 5734 N of pull force, scaling up to a maximum push of 1252 kgf at 1.0 MPa. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal mechanics.
This 1100 mm stroke configuration utilizes a robust Ø32 mm piston rod with an M27x2 thread, paired with a 40 mm adjustable air cushion at both ends to decelerate massive loads smoothly. Because this specific SKU lacks the -S magnet option, it operates without position sensing; if your workflow requires electronic or reed switch feedback, you would need to specify the -S variant to utilize CMSE or DMSE sensors.

Where the Airtac SE125 Standard Cylinder SE125X1100 Is Used
Automotive Body Press Transfer
Leveraging 6136 N of thrust at 0.5 MPa, this cylinder actuates heavy sheet metal transfer arms across a 1100 mm span in automotive stamping lines, relying on the 40 mm cushion to stop high-mass payloads smoothly.
Injection Mold Ejection Gate
Provides the robust 1252 kgf maximum push force required to clear large molded plastic parts from injection machinery, utilizing its hard-chrome Ø32 mm rod to withstand repetitive industrial impact.
Palletizer Diverter Arm
Drives heavy-duty diverter mechanisms in end-of-line packaging systems, where the tie-rod-free extruded profile allows flush mounting into tight conveyor frameworks over the extended 1.1-meter stroke.
Is the Airtac SE125 Standard Cylinder SE125X1100 the Right Cylinder?
Selecting the SE125X1100 is appropriate when your application demands extreme linear thrust over a long 1.1-meter reach. If you need to scale force down, the neighboring 100 mm bore provides 3927 N of push at 0.5 MPa. As the largest standard ISO 15552 bore in this series, stepping up beyond 125 mm requires custom or multi-cylinder solutions. With a 1100 mm stroke, the unsupported rod mass introduces significant bending moments; you must incorporate an external guide mechanism to prevent side-load damage to the rod bearing and seal.
This cylinder functions as a dimensionally interchangeable drop-in replacement for other ISO 15552 profile cylinders, sharing standardized mounting interfaces like TC centre trunnion or LB foot brackets. Remember that the adjustable pneumatic cushioning only decelerates the piston near the stroke endpoints—it does not function as a locking device. If your machinery must hold a vertical load safely without live air pressure, integrate an external rod lock like the BSE series or a pilot-operated check valve.
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 SE125X1100 FAQ
At 0.5 MPa, this 125 mm bore cylinder outputs 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force reaches 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, it is dimensionally interchangeable with other ISO 15552 profile cylinders, sharing identical mounting and port dimensions (PT1/2). This specific SKU does not include a position magnet; for CMSE or DMSE sensor feedback, an -S magnet option must be specified.
