About the Airtac SE125 Standard Cylinder SE125X150
The AirTAC SE125X150 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 extruded aluminum square barrel omits external tie rods entirely, presenting a flush, corrosion-resistant exterior that simplifies mounting and equipment cleanup in harsh industrial settings.
This 125mm bore unit features a Ø32 mm piston rod and PT1/2 porting. Because this specific SKU lacks the built-in magnet suffix, it does not support position sensing without modification. The field-adjustable air cushioning at both stroke ends allows precise deceleration tuning to absorb high kinetic energy, functioning as a true velocity damper rather than a fixed rubber bumper.

Where the Airtac SE125 Standard Cylinder SE125X150 Is Used
Injection Molding Ejectors
Provides the 6136 N push force required to eject heavy molded plastic parts from large injection molding machines, utilizing adjustable cushioning to soften the hard end stops.
Metal Stamping Presses
Handles heavy-duty stamping and forming operations where the 1252 kgf maximum thrust at 1.0 MPa drives dies into thick sheet metal with consistent force.
Palletizing Robot Arms
Actuates heavy-load gripper arms on automated palletizers, where the no-tie-rod profile prevents grease and debris buildup during high-force clamping cycles.
Is the Airtac SE125 Standard Cylinder SE125X150 the Right Cylinder?
Generating 6136 N of thrust at 0.5 MPa, this cylinder is built for high-load tasks. If your application requires less force, stepping down to the 100mm bore variant yields 3927 N of push, which may better suit lighter machinery and conserve air volume. Conversely, the SE125X150 represents the maximum standard bore in the SE family, meaning no larger direct step-up exists within this series.
This model utilizes a PT1/2 port and standard ISO 15552 mounting interface, ensuring drop-in dimensional interchangeability with other profile cylinders of the same standard. Keep in mind that a plain double-acting cylinder drifts when air pressure is lost or a valve is centered; if your machine must hold a load statically without live pressure, consider the BSE rod-lock variant. Additionally, while the robust Ø32 mm rod handles high bending stresses, any stroke length of 300 mm or more necessitates an external guide to prevent rod-bearing deformation.
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.
