Airtac SE125 Standard Cylinder SE125X130
The AirTAC Airtac SE125 Standard Cylinder SE125X130 is a genuine double-acting ISO 15552 / VDMA 24562 profile-barrel air cylinder with a Ø125mm bore and 130mm stroke, PT1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SE125 Standard Cylinder SE125X130
The AirTAC SE125X130 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a formidable 6136 N of push force at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a smooth, corrosion-resistant exterior that mounts flush against machine frames while retaining the standardized ISO 15552 footprint for direct retrofitting.
This 125 mm bore actuator features a 40 mm field-adjustable air cushion at both ends to decelerate heavy payloads smoothly over the 130 mm stroke. Because this specific SKU lacks the built-in -S magnet, it is not prepped for AirTAC CMSE or DMSE position sensing without modification, but its Ø32 mm rod and M27x2 thread provide exceptional rigidity against high side loads.

Where the Airtac SE125 Standard Cylinder SE125X130 Is Used
Metal Stamping Press
Provides the 6136 N push force at 0.5 MPa required to actuate heavy mechanical stamping dies and hold them through the 130 mm working stroke.
Injection Mold Clamping
Secures large plastic injection mold halves using the rigid Ø32 mm rod, relying on the 40 mm adjustable cushion to prevent end-cap shock.
Palletizer Lift Arm
Drives the lifting axis of heavy-duty palletizing arms where the high 1252 kgf maximum output handles substantial payload inertia during retraction.
Is the Airtac SE125 Standard Cylinder SE125X130 the Right Cylinder?
Select this 125 mm bore when your mechanism demands up to 6136 N of push force at 0.5 MPa (8590 N at 0.7 MPa). If your load sits between the 80 mm bore (2513 N push) and this model, stepping up to the 125 mm class is justified for heavy presses or large mold handling. Since this is the largest standard SE bore, there is no larger step-up within the series; if 125 mm is overkill, the 100 mm bore (3927 N push) is the nearest downsize.
Keep in mind that a plain SE cylinder drifts when air is lost or a valve is centered, so it cannot hold a load without live pressure—if your press requires fail-safe position holding, pair it with a BSE rod lock or an external pilot-operated check valve. The 130 mm stroke is below the 300 mm threshold where external guides become strictly mandatory, but the substantial weight of a 125 mm piston still makes a rigid external guide beneficial for preserving the rod-bearing life.
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 SE125X130 FAQ
This cylinder delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N, with an absolute maximum push of 1252 kgf at 1.0 MPa. It features a PT1/2 port, a Ø32 mm rod, and an M27x2 rod-end thread.
Yes, its standardized ISO 15552 mounting dimensions make it a drop-in replacement for other profile cylinders of the same bore. However, it cannot hold a load unpowered; the adjustable air cushion only decelerates the piston near stroke end and does not act as a mechanical lock or brake.
