About the Airtac SE125 Standard Cylinder SE125X210S
The AirTAC SE125X210S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a substantial 6136 N push force at 0.5 MPa, utilizing a 125 mm bore and a 210 mm stroke. The square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while maintaining the standardized ISO 15552 footprint.
Equipped with a built-in magnet (-S), this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection along its three integrated sensor grooves. The field-adjustable air cushioning at both ends allows technicians to tune deceleration via a set screw, softening hard impacts when moving massive loads at speeds up to 30-500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X210S Is Used
Stamping Press Ejection
Provides the robust 6136 N push force required to eject heavy stamped metal panels from a press die, utilizing the 210 mm stroke to clear the bolster completely.
Injection Mold Platen Shift
Shifts a heavy injection molding platen into locking position, relying on the 125 mm bore's massive output and field-adjustable cushions to soften the end-of-stroke impact.
Pallet Diverting Arm
Powers a heavy-duty diverting arm on a packaging line to reroute fully loaded pallets, using the integrated -S magnet to trigger DMSE sensors for confirmation.
Is the Airtac SE125 Standard Cylinder SE125X210S the Right Cylinder?
Selecting the SE125X210S is ideal when your application requires moving heavy payloads, as it provides a maximum push of 1252 kgf at 1.0 MPa. If you need to step down to save air and space, the neighboring 100 mm bore yields 3927 N push at 0.5 MPa; as the largest standard bore, there is no larger neighbor in this series. Because the 210 mm stroke is below the 300 mm threshold, side-load stress on the M27x2 rod is moderate, though external guides are always recommended for rigid loads.
This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders without altering mounting hardware. It uses a PT1/2 port and an M27x2 rod thread. Note that the adjustable cushion only decelerates the piston near stroke end; it does not lock or hold the load. If unpowered drift is a hazard, integrate an external rod lock or pilot-operated check valve.
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.
