About the Airtac SE125 Standard Cylinder SE125X1050S
The AirTAC SE125X1050S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks, yielding a substantial 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a flush, corrosion-resistant exterior that simplifies direct mounting on heavy machinery.
This unit includes a built-in magnet for non-contact position sensing using AirTAC CMSE reed or DMSE electronic switches. Because the stroke is 1050 mm, it is a non-standard made-to-order length exceeding the 1500 mm standard maximum for this bore, and its field-adjustable air cushioning at both ends allows technicians to precisely tune end-of-stroke deceleration for massive 1252 kgf loads.

Where the Airtac SE125 Standard Cylinder SE125X1050S Is Used
Automotive Tier-1 Press Ejection
Provides the 6136 N push force required to eject heavy stamped body panels from hydraulic presses, utilizing the 1050 mm stroke to clear the tooling area completely.
Palletizer Diverter Arm
Actuates a heavy-duty diverter arm on an end-of-line palletizer, relying on the built-in magnet and DMSE electronic sensors to confirm full extension over 1050 mm.
Injection Mold Platen Extraction
Extracts large molded plastic automotive bumpers from injection molding machines, where the adjustable air cushions absorb the kinetic energy of the 1252 kgf capacity drive.
Is the Airtac SE125 Standard Cylinder SE125X1050S the Right Cylinder?
Select this 125 mm bore when your application demands the highest standard thrust in the SE range, generating 6136 N of push at 0.5 MPa. If your load requirement is lighter, stepping down to the 100 mm bore provides 3927 N of push, while the 125 mm bore is the largest available in this series, meaning no larger standard option exists for higher force needs.
At 1050 mm of stroke, the 32 mm rod and rod-end thread M27x2 carry significant side-load leverage, making an external guide carriage strictly necessary to prevent rod-bearing bending and premature seal failure. Remember that the adjustable air cushion only decelerates the piston near the stroke end; it does not hold the load if air pressure drops, so specify a BSE rod lock for fail-safe holding. This unit is dimensionally interchangeable per ISO 15552, accepting standard mounting accessories and PT1/2 ports.
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.
