About the Airtac SE125 Standard Cylinder SE125X10S
The AirTAC SE125X10S 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 robust 125 mm bore and 32 mm hard-chrome plated steel rod handle high side loads, while the square extruded aluminum barrel eliminates external tie rods for a flush, corrosion-resistant mounting surface that simplifies machinery integration.
Equipped with a built-in magnet (S option), this model directly supports AirTAC CMSE reed and DMSE electronic position sensing for precise end-of-stroke verification. The field-adjustable pneumatic cushioning at both ends allows technicians to fine-tune end-stop deceleration, absorbing kinetic energy smoothly across its 30-500 mm/s speed range without relying on fixed rubber bumpers.

Where the Airtac SE125 Standard Cylinder SE125X10S Is Used
Hydraulic Press Ejection
Provides the 8590 N push force at 0.7 MPa needed to eject heavy steel blanks from hydraulic press beds, using the short 10 mm stroke for rapid, high-impact ejection cycles.
Injection Mold Separation
Breaks loose stubborn injection-molded plastic parts from heavy tooling, leveraging the 1252 kgf max output and integrated DMSE sensors to confirm mold release.
Heavy Gauge Metal Stamping
Acts as a powerful hold-down clamp for thick sheet metal stamping operations, applying 6136 N of clamping force at 0.5 MPa while fitting into tight press tooling profiles.
Is the Airtac SE125 Standard Cylinder SE125X10S the Right Cylinder?
Selecting this 125 mm bore is ideal when maximum thrust is required, as it generates 6136 N push at 0.5 MPa and up to 1252 kgf at 1.0 MPa. If your application requires slightly less force, stepping down to the 100 mm bore yields 3927 N push at 0.5 MPa, but if you need the absolute highest output available in the SE range, this is the largest standard option. Because the stroke is only 10 mm, side-load stress on the rod bearing is minimal, though heavy loads should still be guided externally. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 profile cylinders using the same PT1/2 port and standard mounting accessories.
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 SE125X10S FAQ
The SE125X10S delivers a push force of 6136 N and a pull force of 5734 N at 0.5 MPa. At 0.7 MPa, the push force is 8590 N, with a maximum push of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
No, the SE125X10S is a double-acting cylinder and cannot hold a load without live air pressure. Its adjustable air cushions only decelerate the piston near the stroke ends; they are not locks. For position holding, consider an external rod lock or the AirTAC BSE series.
