About the Airtac SE125 Standard Cylinder SE125X110
The AirTAC SE125X110 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty linear motion. Operating at 0.5 MPa, it generates a substantial 6136 N of push force and 5734 N of pull force, scaling up to a maximum push of 1252 kgf at 1.0 MPa. The extruded aluminum barrel design omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames.
This 125 mm bore unit features a robust 32 mm piston rod and a PT1/2 port. Field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts when moving massive loads at speeds up to 30-500 mm/s. Note that this specific SKU is configured without a position-sensing magnet, so it does not directly support AirTAC CMSE or DMSE switches without modification.

Where the Airtac SE125 Standard Cylinder SE125X110 Is Used
Metal Stamping Press
Drives a 110 mm stroke blanking die with 6136 N of push force at 0.5 MPa, utilizing the adjustable cushion to absorb the shock of heavy sheet metal impact.
Injection Mold Ejection
Actuates a large mold ejection plate over a 110 mm travel distance, relying on the 32 mm rod to withstand high off-center side loads during part stripping.
Automotive Assembly Rig
Clamps heavy chassis components securely in a welding fixture, using the tie-rod-free extruded profile to mount flush and avoid robotic arm interference.
Is the Airtac SE125 Standard Cylinder SE125X110 the Right Cylinder?
Selecting the SE125X110 is appropriate when your application demands extreme thrust, such as pressing or heavy lifting tasks requiring 6136 N of push at 0.5 MPa. If your load requirements are slightly lower, stepping down to the 100 mm bore provides 3927 N of push, which may offer a more compact footprint and lower air consumption. Conversely, this 125 mm bore is the largest standard SE size available, meaning further force escalation requires custom or multi-cylinder arrangements. As a true ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, utilizing standardized mounting accessories like FA or LB brackets. Keep in mind that the integrated air cushion only decelerates the piston near stroke end; it does not hold the load if air pressure is lost. For position-holding safety, explore the BSE rod-lock variant.
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 SE125X110 FAQ
At 0.5 MPa, the SE125X110 delivers 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 operational speed range for this 125 mm bore cylinder is 30-500 mm/s.
No, the adjustable air cushion at both ends only decelerates the piston near the stroke limits and acts as a shock absorber, not a mechanical lock. If air pressure is lost or the valve is centered, the cylinder will drift. For secure load holding, you should use the BSE variant equipped with a rod lock.
