About the Airtac SE125 Standard Cylinder SE125X140
The AirTAC SE125X140 is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, delivering a substantial 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel eliminates external tie rods, yielding a compact, corrosion-resistant body that mounts flush while resisting mechanical snagging in dense machinery layouts. This 125 mm bore unit operates at 30-500 mm/s and features a robust Ø32 mm piston rod with an M27x2 thread.
Because this specific SKU lacks the -S magnet code, it is not equipped out-of-the-box for CMSE or DMSE electronic position sensing. Field-adjustable air cushioning at both stroke ends allows technicians to tune end-of-stroke deceleration via a set screw, softening hard mechanical stops to protect massive moving loads from impact shock.

Where the Airtac SE125 Standard Cylinder SE125X140 Is Used
Automotive Stamping Press
Provides the 6136 N push at 0.5 MPa required to actuate heavy lower dies and secure stamping blanks in automotive panel forming machinery.
Heavy-Duty Metal Bending
Drives the clamp on thick-gauge hydraulic press brakes, utilizing the 140 mm stroke to position tooling rapidly before high-tonnage forming.
Pallet Dispenser Gate
Shifts loaded pallet dispenser gates in high-throughput logistics hubs, where the 5734 N pull force easily retracts the 125 mm bore against mechanical drag.
Is the Airtac SE125 Standard Cylinder SE125X140 the Right Cylinder?
Selecting this 125 mm bore cylinder makes sense when your application demands up to 6136 N of push at 0.5 MPa or 1252 kgf at 1.0 MPa. If your load requirement is lighter, the neighbouring 100 mm bore provides 3927 N push at 0.5 MPa, offering a more compact, lighter-motion solution. Conversely, if you need even greater thrust, the 125 mm bore is the largest standard SE size available, meaning heavier demands will require dual-cylinder setups or larger custom actuators. At 140 mm stroke, side-load bending on the rod bearing is minimal, though heavy radial loads still necessitate an external guide. Remember that a standard SE does not hold its position when air is exhausted; if your machine requires fail-safe load holding, specify the BSE rod-lock variant instead. For retrofitting, this model is dimensionally interchangeable per ISO 15552 standards, using a 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 SE125X140 FAQ
The SE125X140 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 an absolute maximum push of 1252 kgf at 1.0 MPa. The operational speed range for this 125 mm bore actuator is 30-500 mm/s.
