About the Airtac SE125 Standard Cylinder SE125X385S
The AirTAC SE125X385S is a double-acting single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a robust 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 against machine frames while protecting internal mechanics.
Equipped with a built-in magnet (-S), this unit seamlessly 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 tune deceleration dynamically, softening the impact of the 32 mm rod at high traverse speeds without relying on fixed rubber bumpers.

Where the Airtac SE125 Standard Cylinder SE125X385S Is Used
Injection Mold Clamping
Provides the 8590 N thrust at 0.7 MPa needed to secure heavy injection mold halves within a 385 mm travel envelope during high-pressure resin injection.
Press Brake Actuation
Drives the upper beam of a sheet metal press brake, utilizing the 125 mm bore's 1252 kgf maximum output to form thick structural steel plates.
Pallet Elevator Drive
Lifts loaded pallets in automated high-bay warehouse systems, relying on the 385 mm stroke and built-in DMSE electronic sensors for precise tier alignment.
Is the Airtac SE125 Standard Cylinder SE125X385S the Right Cylinder?
Generating 6136 N of thrust at 0.5 MPa, this 125 mm bore cylinder sits at the top of the SE standard range, meaning there is no larger standard bore to step up to. If your application does not require this maximum force, stepping down to the 100 mm bore variant reduces air consumption while still providing a 3927 N push at 0.5 MPa. Because the 385 mm stroke exceeds the 300 mm threshold, the unsupported piston rod is highly susceptible to bending under lateral loads; always utilize an external guide rail to prevent rod-bearing damage.
For retrofitting, this model is dimensionally interchangeable with any true ISO 15552 cylinder, utilizing a PT1/2 port and an M27x2 rod thread. Note that while the adjustable air cushions soften end-of-stroke impacts, they are not locking devices; the piston will drift if air pressure is lost or the directional control valve is centered. For static holding requirements, consider a BSE rod lock variant.
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 SE125X385S FAQ
This 125 mm bore cylinder delivers 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, and a maximum of 1252 kgf at 1.0 MPa. The operational speed range is 30-500 mm/s.
Yes, the SE125X385S is dimensionally interchangeable per ISO 15552 standards, meaning it shares identical mounting footprint and pin dimensions. You can reuse existing FA flanges or TC trunnion blocks, but ensure your plumbing matches its PT1/2 port.
