About the Airtac SE125 Standard Cylinder SE125X65S
The AirTAC SE125X65S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It features a robust 125 mm bore and a 65 mm stroke, generating a substantial 6136 N of push force at 0.5 MPa and up to 8590 N at 0.7 MPa. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while protecting internal mechanics.
This specific unit includes a built-in magnet (-S) for seamless integration with AirTAC CMSE reed and DMSE electronic position sensors across its three-side sensor grooves. Field-adjustable pneumatic cushioning at both ends allows technicians to fine-tune end-of-stroke deceleration via a set screw, softening hard mechanical stops for high-mass loads moving at speeds up to 30-500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X65S Is Used
Injection Mold Clamping
Delivers 6136 N of push at 0.5 MPa to secure heavy injection mold halves during material injection, utilizing the adjustable cushion to absorb sudden impact.
Pallet Stopper Arms
Halt loaded pallets on high-throughput packaging lines; the 125 mm bore provides the necessary stopping force without bouncing the load.
Press Brake Tooling
Positions heavy upper press brake tooling with precision, relying on the M27x2 rod thread and 1252 kgf maximum thrust for deep bending operations.
Is the Airtac SE125 Standard Cylinder SE125X65S the Right Cylinder?
If your assembly requires less thrust, stepping down to the 100 mm bore yields 3927 N of push at 0.5 MPa, whereas no larger standard bore exists in this series. Because this is a standard double-acting cylinder, it relies on continuous air pressure to maintain its position; if air is lost or the valve centers, the piston will drift. For applications demanding static load holding without live pressure, consider the BSE rod-lock variant. As a dimensionally interchangeable ISO 15552 cylinder, this model serves as a direct drop-in replacement for other ISO 15552 profile cylinders, utilizing the existing PT1/2 port and standard 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 SE125X65S FAQ
At 0.5 MPa, it provides 6136 N of push and 5734 N of pull. At 0.7 MPa, the push force is 8590 N, with a maximum push of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
It is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other profile cylinders using the same mounting interface. However, it is a standard double-acting cylinder, so it does not hold position without air pressure; use a BSE rod lock for fail-safe holding.
