About the Airtac SE125 Standard Cylinder SE125X600
The AirTAC SE125X600 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It utilizes a square extruded aluminum barrel without external tie rods, yielding a compact, corrosion-resistant body that mounts flush. Operating at 0.5 MPa, it generates 6136 N of push force and 5734 N of pull force, scaling up to a maximum of 1252 kgf at 1.0 MPa.
Because this specific SKU lacks the -S magnet code, it is not pre-configured for CMSE or DMSE electronic position sensing out of the box. Field-adjustable air cushions at both ends allow technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when moving massive loads at speeds up to 500 mm/s. The extruded profile also features integrated sensor grooves on three sides, allowing easy retrofit of switches if future automation upgrades require position feedback.

Where the Airtac SE125 Standard Cylinder SE125X600 Is Used
Automotive Stamping Press Ejection
Ejects heavy stamped metal body panels from hydraulic presses, utilizing the 6136 N push force to overcome die friction and strip the large parts reliably.
Heavy Press Brake Bending
Actuates the hold-down clamps on a large CNC press brake, ensuring thick steel plates remain securely pinned against the backgauge during high-tonnage bending operations.
Palletizer Load Displacement
Drives the horizontal transfer arm on an end-of-line robotic palletizer, moving stacked goods along a 600 mm stroke at controlled speeds without external hydraulics.
Is the Airtac SE125 Standard Cylinder SE125X600 the Right Cylinder?
Selecting the SE125X600 is appropriate when your application demands the highest standard force tier in the SE range. If you need to step down, the adjacent 100 mm bore provides 3927 N of push at 0.5 MPa, which may suffice for lighter loads. Stepping up is not an option as 125 mm is the largest standard bore, making this the definitive choice for maximum thrust requirements within the series. This 600 mm stroke configuration uses a PT1/2 port and an M27x2 rod thread.
Since the 600 mm stroke exceeds the 300 mm threshold, the unsupported rod length introduces a risk of rod-bearing bending under heavy lateral loads; utilizing an external guide rail is strongly recommended to prevent premature seal wear. Remember that a standard SE cylinder does not hold its position or brake a load when air pressure is lost or the valve is centered—the piston will drift. If your machinery must safely suspend or lock a load without live pressure, integrate an external rod lock or pilot-operated check valve. Dimensionally interchangeable per ISO 15552, this cylinder serves as a drop-in replacement for other ISO 15552 cylinders, sharing standardized mounting hardware.
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 SE125X600 FAQ
The SE125X600 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 reaches 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range for this 125 mm bore is 30-500 mm/s.
Yes, it is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders without modifying your mounting footprint. Regarding safety, a standard SE cylinder does not hold its position when air is exhausted or the valve is centered; the piston will drift. For load-holding without live pressure, an external rod lock or pilot-operated check valve is required.
