About the Airtac SE125 Standard Cylinder SE125X210
The AirTAC SE125X210 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a substantial 6136 N push at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while surviving rigorous washdown environments.
This specific SKU is configured without a position-sensing magnet and uses the standard PT1/2 port. To absorb the kinetic energy of its large 32 mm piston rod moving at up to 30-500 mm/s, the cylinder incorporates field-adjustable air cushioning at both ends, allowing technicians to tune end-of-stroke deceleration via a set screw rather than relying on fixed rubber bumpers.

Where the Airtac SE125 Standard Cylinder SE125X210 Is Used
Automotive Stamping Press
Drives heavy lower dies into the clamp position on a 200-ton stamping press, utilizing the 6136 N push force to secure the tooling before the hydraulic system engages.
Injection Mold Ejection
Actuates the primary ejection plate on a large-format plastic injection molding machine, where the 210 mm stroke safely clears the molded part from the deep cavity.
Structural Beam Straightener
Applies localized corrective bending force to thick-walled steel tubing in a structural fabrication line, relying on the 8590 N output at 0.7 MPa to yield the material.
Is the Airtac SE125 Standard Cylinder SE125X210 the Right Cylinder?
Selecting this 125 mm bore unit makes sense when your application requires extreme force, generating 6136 N of push at 0.5 MPa. If you need slightly less thrust, stepping down to the 100 mm bore yields 3927 N push at 0.5 MPa; conversely, the 125 mm is the largest standard SE size available, making it the definitive choice for maximum pneumatic output up to 1252 kgf at 1.0 MPa.
Because this unit lacks a -S magnet, it cannot host CMSE or DMSE position sensors without modification. As a made-to-order 210 mm stroke exceeding the standard 200 mm increment, it retains full ISO 15552 mounting interchangeability for existing brackets. Note that a plain double-acting cylinder drifts when air pressure is lost; if your process demands strict load holding during exhaust or valve centering, integrate an external pilot-operated check valve or specify a 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 SE125X210 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, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, the SE125X210 is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other ISO 15552 profile cylinders, matching the bore, 210 mm stroke, PT1/2 port, and mounting hardware without altering the machine footprint.
