About the Airtac SE125 Standard Cylinder SE125X500S
The AirTAC SE125X500S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. It generates 6136 N of push force at 0.5 MPa and features a robust 32 mm hard-chrome piston rod. The extruded aluminum barrel omits external tie rods, yielding a compact, flush-mounting footprint that resists corrosion while simplifying sensor placement along its three integrated grooves.
This 125 mm bore unit includes a built-in magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic switches. Field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration, softening mechanical impacts when moving heavy payloads across its 500 mm travel.

Where the Airtac SE125 Standard Cylinder SE125X500S Is Used
Automotive Press Ejection
Provides 6136 N of push force at 0.5 MPa to reliably eject heavy stamped metal body panels from mechanical presses, utilizing its 500 mm stroke to clear the die area completely.
Injection Mold Separation
Leverages the 125 mm bore's 8590 N extend force at 0.7 MPa to break the vacuum and separate large injection-molded plastic housings from their core pins during automated demolding.
Heavy Steel Straightening
Applies up to 1252 kgf of maximum thrust to compress and align structural steel I-beams in a fabrication jig, using the adjustable end cushions to soften the high-speed impact.
Is the Airtac SE125 Standard Cylinder SE125X500S the Right Cylinder?
Delivering 6136 N push at 0.5 MPa, this 125 mm bore cylinder is the largest in the SE standard lineup. If your application requires less force, stepping down to the 100 mm bore yields 3927 N push, but if you need maximum thrust, this is the premier choice offering 8590 N at 0.7 MPa. Because the 500 mm stroke is substantial, the 32 mm rod and internal bearing face bending moments under lateral loads; always utilize an external guide rail to prevent side-loading damage. Remember that the adjustable air cushion only decelerates the piston near stroke end—it does not hold a load. If your system loses air pressure, the rod will drift; for fail-safe position holding, pair this cylinder with a BSE rod lock variant or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for other ISO 15552 cylinders, sharing standard mounting hardware like TC trunnions and FA flanges.
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 SE125X500S FAQ
At 0.5 MPa, the 125 mm bore provides 6136 N of push (extend) force and 5734 N of pull (retract) force. At 0.7 MPa, the push force reaches 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, it is dimensionally interchangeable with any ISO 15552 profile cylinder, allowing you to reuse existing mounting brackets and FA/TC accessories. The built-in -S magnet is specifically designed to trigger AirTAC CMSE reed switches and DMSE electronic sensors for precise end-position detection.
