About the Airtac SE125 Standard Cylinder SE125X105S
The AirTAC SE125X105S 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 105 mm stroke make it a powerhouse for moving substantial masses in demanding industrial environments.
Unlike traditional tie-rod designs, this cylinder utilizes a square extruded aluminum barrel without external tie rods, ensuring a compact, corrosion-resistant footprint that mounts flush against machine frames. The integrated -S magnet enables seamless position tracking with AirTAC CMSE reed and DMSE electronic sensors, while the field-adjustable pneumatic cushioning at both ends allows you to fine-tune end-of-stroke deceleration for heavy loads moving at up to 500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125X105S Is Used
Injection Mold Clamping
Provides the 6136 N push force required to secure heavy injection mold halves and large stamping dies during high-pressure forming operations.
Press Brake Actuation
Drives the heavy upper beam of an automotive press brake, utilizing its 105 mm stroke and adjustable cushions to absorb high kinetic energy at the stroke ends.
Palletizer Lift Arm
Raises loaded pallets in end-of-line packaging systems, where the built-in magnet triggers DMSE electronic sensors to confirm the lift position under heavy 125 mm bore loads.
Is the Airtac SE125 Standard Cylinder SE125X105S the Right Cylinder?
In this 125 mm bore class, the SE125X105S provides 6136 N of push force at 0.5 MPa. If your application requires less force, stepping down to the 100 mm bore yields 3927 N of push at 0.5 MPa; as the largest standard SE bore, there is no larger step-up available in this series. Because the 105 mm stroke is under 300 mm, standard rod-bearing bending is minimal, though heavy lateral loads should still utilize an external guide. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders, utilizing the standard PT1/2 port, M27x2 rod thread, and your choice of ISO mounting hardware. Note that this cylinder relies on live air pressure to move; it will drift if air is lost, so use a BSE variant or external rod lock for position holding.
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 SE125X105S FAQ
At 0.5 MPa, the push force is 6136 N and the pull force is 5734 N. At 0.7 MPa, the push force is 8590 N, with a maximum push capacity of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
No, the adjustable air cushions at both ends only decelerate the piston near the end of the stroke and do not lock the rod. If your application requires holding a load without live air pressure, you should use an AirTAC BSE rod-lock cylinder or an external pilot-operated check valve.
