About the Airtac SE125 Standard Cylinder SE125BX160
The AirTAC SE125BX160 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatics, delivering a substantial 6136 N push force at 0.5 MPa. Its square extruded aluminum barrel omits external tie rods, yielding a compact, corrosion-resistant body that mounts flush against machine frames while exposing sensor grooves on three sides for flexible switch placement.
This specific SKU features a SUS304 stainless steel piston rod (option B), making it highly suitable for corrosive environments or washdown manufacturing lines. Unlike a fixed rubber bumper, the field-adjustable pneumatic cushioning at both ends allows technicians to dial in the exact deceleration needed to soften hard end stops at operating speeds up to 30-500 mm/s.

Where the Airtac SE125 Standard Cylinder SE125BX160 Is Used
Heavy Pallet Strapping
Drives a high-tonnage strapping and sealing head on outbound pallet lines, utilizing the 6136 N push force to crimp steel straps securely.
Washdown Sorting Diverter
Leverages the SUS304 rod to push heavy product flows into processing lanes in food-grade environments requiring daily high-pressure washdowns.
Press Die Ejection
Extracts dense stamped metal components from heavy tooling, relying on the 40 mm adjustable cushion to decelerate the 125 mm bore safely at stroke end.
Is the Airtac SE125 Standard Cylinder SE125BX160 the Right Cylinder?
In this 125 mm bore class, the SE125BX160 outputs 6136 N push and 5734 pull at 0.5 MPa (8590 N push at 0.7 MPa). If your application requires less force, stepping down to the 100 mm bore reduces the 0.5 MPa push to 3927 N, whereas moving up is not an option as 125 mm is the largest standard SE diameter. Because this is a single-rod double-acting cylinder, it cannot hold a load unpowered—air loss causes drift, so integrate an external BSE rod lock or pilot-operated check valve for vertical positioning. The 160 mm stroke is well within standard limits, so side-load stress on the M27x2 thread and Ø32 mm rod is minimal, though external guides remain best practice for rigid payloads.
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 SE125BX160 FAQ
The SE125BX160 generates 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push at 0.7 MPa, and a maximum push of 1252 kgf at 1.0 MPa. It uses a PT1/2 port and operates at 30-500 mm/s.
Yes, the SE profile cylinder is dimensionally interchangeable per ISO 15552 standards, meaning it shares the exact mounting footprint and can serve as a drop-in replacement for other ISO 15552 cylinders without altering the existing mounting hardware.
