About the Airtac SE125 Standard Cylinder SE125X160S
The AirTAC SE125X160S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a robust 6136 N push force at 0.5 MPa. Its extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames without protruding hardware.
Equipped with a built-in magnet (-S), this unit seamlessly integrates AirTAC CMSE reed and DMSE electronic sensors for precise end-of-stroke detection. The field-adjustable pneumatic cushioning at both ends allows technicians to tune deceleration via a set screw, softening hard mechanical impacts during high-mass cycling.

Where the Airtac SE125 Standard Cylinder SE125X160S Is Used
Automotive Stamping Press Ejection
Uses the 6136 N push force to reliably eject heavy stamped metal body panels from large press dies, leveraging the adjustable cushion to absorb high kinetic energy at stroke end.
Heavy Press Brake Bending
Provides the massive clamping thrust required to hold thick steel plates stationary during industrial press brake bending operations.
Palletizer Transfer Carriage
Drives a heavy-load transfer carriage in automated palletizing cells, using the built-in magnet and DMSE sensors to confirm carriage positioning.
Is the Airtac SE125 Standard Cylinder SE125X160S the Right Cylinder?
This 125mm bore provides massive thrust, but if your application requires less force, stepping down to the 100mm bore yields 3927 N push at 0.5 MPa, which may better suit medium-duty tasks. If even higher force is necessary, this is the largest standard SE bore available, so exceeding its 1252 kgf maximum capacity at 1.0 MPa would require twin cylinders or a larger custom actuator. Because it is dimensionally interchangeable per ISO 15552, it serves as a direct drop-in replacement for other ISO 15552 cylinders, matching the 125mm bore, 160mm stroke, PT1/2 port, and standard mounting accessories.
Note that a plain SE cylinder does not hold its position or load when air is exhausted or the valve is centered; the piston drifts. If your application must hold a vertical load without live pressure, consider the BSE rod-lock variant or an external pilot-operated check valve. Additionally, while the 32mm rod and M27x2 thread handle significant side loads, any stroke of 300mm or more requires an external guide to prevent rod-bearing bending.
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.
