About the Airtac SE125 Standard Cylinder SE125X5S
The AirTAC SE125X5S is a double-acting single-rod ISO 15552 profile cylinder engineered for extreme force in ultra-short movements. It delivers a massive 6136 N push force at 0.5 MPa (8590 N at 0.7 MPa) across a 5 mm stroke, making it ideal for high-impact pressing and clamping tasks.
The extruded aluminum barrel omits external tie rods, yielding a clean, corrosion-resistant body that mounts flush in tight machine cells. Equipped with a built-in magnet, it directly supports AirTAC CMSE reed and DMSE electronic position sensors for precise end-of-stroke verification.

Where the Airtac SE125 Standard Cylinder SE125X5S Is Used
Punch Press Stamping
Provides the 6136 N push force required to drive small-diameter stamping pins into sheet metal within a compact 5 mm stroke.
Injection Mold Closing
Rapidly clamps lightweight mold halves shut using high 125 mm bore thrust, verifying closure with the built-in magnet and DMSE sensors.
Bearing Seating
Delivers an abrupt 8590 N impact at 0.7 MPa to press bearings flush into housing bores without requiring a long cylinder stroke.
Is the Airtac SE125 Standard Cylinder SE125X5S the Right Cylinder?
This 125 mm bore model provides the heaviest thrust in the SE line, but if you need to step down for efficiency, the 100 mm bore yields 3927 N push at 0.5 MPa. Because 125 mm is the maximum bore, there is no larger neighbor to step up to. As a standard ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, matching the PT1/2 port, M27x2 rod thread, and standard mounting accessories.
Because the stroke is only 5 mm, the rigid 32 mm rod handles side loads well without flexure. However, the field-adjustable air cushions at both ends only decelerate the piston near the stroke end; they do not hold the load. If your process loses air pressure, the piston will drift, so an external pilot-operated check valve is required for position holding.
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 SE125X5S FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, the push force is 8590 N. The maximum push force is 1252 kgf at 1.0 MPa, and the operating speed range is 30-500 mm/s.
Yes, it is dimensionally interchangeable with other ISO 15552 profile cylinders. However, the adjustable air cushions only decelerate the piston near the stroke end; they do not lock or hold the load. If air is lost, the piston will drift unless an external rod lock is used.
