About the Airtac SE125 Standard Cylinder SE125X480S
The AirTAC SE125X480S is a double-acting single-rod ISO 15552 profile cylinder built for heavy-duty linear motion. It generates a substantial 6136 N push at 0.5 MPa, utilizing a 125 mm bore and a 480 mm stroke. The extruded aluminum barrel design 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 directly supports AirTAC CMSE reed and DMSE electronic position sensors without requiring external hardware. The field-adjustable pneumatic cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening the impact of heavy 1252 kgf maximum loads moving at up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X480S Is Used
Injection Mold Platen Ejection
Provides the heavy 6136 N push at 0.5 MPa required to eject dense plastic parts from injection molding platens, utilizing the 480 mm stroke to clear the mold entirely.
Automotive Press Deflashing
Drives heavy-duty deflashing blades on automotive stamping lines, where the 125 mm bore output and adjustable cushioning absorb the shock of high-tonnage trimming operations.
Palletizer Transfer Carriage
Actuates the horizontal transfer carriage on robotic palletizers, moving fully loaded pallets with the 1252 kgf maximum capacity while DMSE sensors track the 480 mm travel.
Is the Airtac SE125 Standard Cylinder SE125X480S the Right Cylinder?
Selecting the SE125X480S is appropriate when your application demands up to 8590 N of push force at 0.7 MPa. If you need to scale down, the neighboring 100 mm bore provides 3927 N of push at 0.5 MPa; as the largest standard size in this series, there is no larger bore option available to step up to. Because this model features a 480 mm stroke, the 32 mm rod and internal bearing face significant bending moments under side loads—always incorporate an external guide rail to prevent premature seal wear.
This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders. It carries a PT1/2 port, a 40 mm cushion length, and the -S magnet specification. Remember that the adjustable air cushion only decelerates the piston near stroke end; it is not a locking device. If the machine loses air pressure, the rod will drift, so integrate a BSE rod lock or external pilot-operated check valve for strict load-holding requirements.
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 SE125X480S FAQ
The SE125X480S delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N. The maximum push force is 1252 kgf when operated at the 1.0 MPa pressure limit.
No, the adjustable air cushion only decelerates the piston near the end of the stroke and does not act as a brake. If the air supply is lost, the rod will drift. For position holding, you must use an external rod lock or pilot-operated check valve.
