About the Airtac SE125 Standard Cylinder SE125X125
The AirTAC SE125X125 is a double-acting single-rod ISO 15552 profile cylinder built for heavy-duty linear motion. It delivers a substantial 6136 N push force at 0.5 MPa, scaling up to 8590 N at 0.7 MPa. The extruded aluminum barrel design omits external tie rods, yielding a compact, flush-mounting body that resists corrosion and simplifies bracket installation.
This 125 mm bore unit features a robust 32 mm piston rod and a PT1/2 port. Field-adjustable air cushioning at both stroke ends allows technicians to tune deceleration, softening hard impacts when moving massive payloads at up to 500 mm/s. Note this specific SKU lacks a position-sensing magnet; integrating CMSE or DMSE switches requires an -S option code at ordering.

Where the Airtac SE125 Standard Cylinder SE125X125 Is Used
Metal Stamping Press
Drives heavy stamping dies requiring 8590 N of extend force at 0.7 MPa to form thick gauge sheet metal components.
Injection Mold Ejection
Provides the raw 6136 N push at 0.5 MPa needed to break loose and eject large molded plastic parts from heavy tooling.
Hydraulic Press Brake
Acts as a pneumatic actuator for heavy-duty bending operations, utilizing the 125 mm bore to generate consistent high-tonnage clamping.
Is the Airtac SE125 Standard Cylinder SE125X125 the Right Cylinder?
Selecting the SE125X125 makes sense when your application requires extreme force, such as pressing or heavy lifting, demanding the maximum 1252 kgf available at 1.0 MPa. If you need to step down to reduce physical size and air consumption, the neighboring 100 mm bore provides 3927 N push at 0.5 MPa. As the largest standard profile size, stepping up beyond 125 mm requires custom or multi-cylinder solutions. Because this is a standard 125 mm stroke under the 1500 mm maximum, it drops in seamlessly as a dimensionally interchangeable replacement for any ISO 15552 cylinder using standard mounting accessories. Remember that the adjustable end cushions only decelerate the piston near stroke end; they do not hold the load. If air pressure drops, the rod will drift, so pilot-operated check valves or a BSE rod lock variant are required for fail-safe holding.
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 SE125X125 FAQ
The SE125X125 generates 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. The maximum push force is 1252 kgf at 1.0 MPa. The operating speed range for this 125 mm bore cylinder is 30-500 mm/s.
This specific SKU does not include a magnet, so it cannot host CMSE or DMSE position sensors without ordering the -S option. Dimensionally, it is a true ISO 15552 profile cylinder, meaning it serves as a drop-in replacement for other ISO 15552 cylinders using standard mounting hardware, without relying on external tie rods.
