About the Airtac SE125 Standard Cylinder SE125X700S
The AirTAC SE125X700S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a substantial 6136 N push force at 0.5 MPa. Its 125 mm bore and 700 mm stroke provide the extended travel needed for large-scale automation, while the square extruded aluminum barrel omits external tie rods for a compact, corrosion-resistant footprint that mounts flush against machine frames.
This specific unit includes a built-in magnet (-S) for non-contact position detection using AirTAC CMSE reed or DMSE electronic sensors. To manage the high kinetic energy of a 32 mm rod moving a heavy load at speeds up to 30-500 mm/s, the cylinder integrates field-adjustable air cushioning at both ends, allowing technicians to fine-tune end-of-stroke deceleration and eliminate hard mechanical impacts.

Where the Airtac SE125 Standard Cylinder SE125X700S Is Used
Automotive Press Die Handling
Utilizes the 6136 N push force at 0.5 MPa to lift and position heavy stamping dies into large mechanical presses, relying on the 700 mm stroke for deep reach.
Palletizer Transfer Arm
Deploys the 125 mm bore's high thrust to push fully loaded pallets onto outbound conveyor chains, using the adjustable cushion to soften stops at high speeds.
Heavy-Duty CNC Door Actuation
Drives the massive safety doors of large-scale CNC machining centers, where the -S magnet triggers DMSE electronic sensors to confirm secure closure before cycle start.
Is the Airtac SE125 Standard Cylinder SE125X700S the Right Cylinder?
Selecting the SE125X700S is appropriate when your application requires maximum thrust; stepping down to the 100 mm bore reduces the 0.5 MPa push force to 3927 N, while no larger standard SE bore exists above this 125 mm class (which hits 8590 N push at 0.7 MPa and 1252 kgf max at 1.0 MPa). Because this model features a 700 mm stroke, the unsupported piston rod is highly susceptible to bending under lateral loads—an external guide or linear rail must be used to prevent rod-bearing damage. As a double-acting cylinder, it will drift if air pressure is lost; for fail-safe load holding, consider the BSE rod lock variant. This model uses a PT1/2 port and is dimensionally interchangeable with any ISO 15552 mounting hardware.
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 SE125X700S FAQ
The SE125X700S provides a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force reaches 8590 N, with an absolute maximum push of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
