About the Airtac SE125 Standard Cylinder SE125X60S
The AirTAC SE125X60S is a heavy-duty double-acting single-rod profile cylinder built to the ISO 15552 standard. It delivers a substantial 6136 N push force at 0.5 MPa, making it well suited for high-thrust automation tasks. The extruded aluminum barrel design omits external tie rods, yielding a compact body that resists corrosion and mounts flush against machine frames.
This 125 mm bore unit includes a built-in magnet for position detection and operates at speeds of 30-500 mm/s. Field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, protecting the mechanism from hard impacts during rapid cycling.

Where the Airtac SE125 Standard Cylinder SE125X60S Is Used
Stamping Press Feed
Drives heavy metal blanks into a hydraulic stamping press, utilizing the 6136 N push force to overcome material resistance and seat the part firmly.
Injection Mold Clamping
Secures the lower half of a polymer injection mold, using the high 125 mm bore thrust to prevent mold separation under high cavity pressure.
Pallet Stopper Gate
Acts as a heavy-duty physical stop barrier on a conveyor line, arresting the momentum of loaded pallets before they enter the stretch-wrap station.
Is the Airtac SE125 Standard Cylinder SE125X60S the Right Cylinder?
Selecting this 125 mm bore cylinder is appropriate when an application requires the maximum standard thrust available in the SE range, generating 6136 N push at 0.5 MPa. If your load requires less force, stepping down to the 100 mm bore provides 3927 N push at 0.5 MPa, which may offer a lighter footprint and faster cycle times. As the largest standard size, there is no larger neighbour in this series.
The 60 mm stroke keeps the rod fully supported within the bearing for minimal deflection. Because this is a plain double-acting cylinder, it will drift if air pressure is lost or the valve is centered; if the machinery must hold a vertical load safely without live pressure, integrate an external rod lock or a pilot-operated check valve. This model is dimensionally interchangeable with other ISO 15552 profile cylinders, accepting standard mounting accessories and PT1/2 port connections.
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 SE125X60S FAQ
At 0.5 MPa, this 125 mm bore cylinder provides 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 at 1.0 MPa. The operating speed range is 30-500 mm/s.
