About the Airtac SE125 Standard Cylinder SE125BX600S
The AirTAC SE125BX600S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a robust 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush on machinery while resisting mechanical snags.
This specific configuration features a SUS304 stainless steel rod for superior corrosion and washdown resistance, paired with a built-in magnet for CMSE and DMSE position sensing. The field-adjustable air cushioning at both ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard impacts during high-speed 30-500 mm/s cycling.

Where the Airtac SE125 Standard Cylinder SE125BX600S Is Used
Heavy Press Ejection
Ejecting large stamped metal panels from a 1000-ton press, utilizing the 6136 N push force and 600 mm stroke to safely clear the die area.
Palletizer Strapping
Tensioning and sealing steel strapping around heavy palletized goods, where the SUS304 rod withstands abrasive packaging environments.
Casting Demolding
Pushing cured concrete or resin molds out of industrial casting tables, relying on the adjustable cushioning to soften the 600 mm travel end-stop.
Is the Airtac SE125 Standard Cylinder SE125BX600S the Right Cylinder?
Selecting this 125 mm bore model makes sense when the 80 mm variant's 2513 N push at 0.5 MPa is insufficient for your heaviest loads. If you require even more force, 125 mm is the largest standard SE bore, so stepping up would require a twin-cylinder setup or a larger non-standard actuator. Keep in mind that a plain SE cylinder drifts when air is lost or valves are centered; if your 600 mm stroke application must hold a vertical load without live pressure, integrate an external BSE rod lock or pilot-operated check valve.
For a 600 mm stroke, the unsupported piston rod is highly susceptible to side-load bending and bearing wear; always mount an external guide rail to support the load and prevent rod damage. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders, utilizing the standard PT1/2 port and your chosen mounting accessories alongside the -S magnet.
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.
