About the Airtac SAI125 Standard Air Cylinder SAI125X80S
The AirTAC SAI125X80-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 6136N push force at 0.5 MPa, it is tailored for short-stroke, high-thrust tasks. The integrated magnet enables seamless position tracking using CMSE or DMSE reed switches fitted into the dual sensor grooves.
This variant features a standard carbon steel piston rod and PT tapered port threads, ensuring a leak-free, high-pressure pneumatic connection. As a genuine AirTAC component, it provides a dimensionally exact drop-in replacement for any ISO 15552 profile cylinder without compromising your existing mounting layout.

Where the Airtac SAI125 Standard Air Cylinder SAI125X80S Is Used
Heavy Metal Stamping
Generates the 6136N force required to press and form thick gauge metal components in automated fabrication cells.
Large Mold Clamping
Provides reliable short-stroke clamping force to secure heavy industrial molds during injection or casting cycles.
Pallet Diverter
Actuates heavy-duty routing gates on high-mass pallet conveyors where substantial side resistance is present.
Is the Airtac SAI125 Standard Air Cylinder SAI125X80S the Right Cylinder?
Choose this 125mm bore when 80mm of travel is sufficient but substantial push power is required. If your application needs less force, stepping down to the 100mm bore yields 3927N at 0.5 MPa, while moving up to the 160mm bore provides 10053N for extreme loads. Because the stroke is under 300mm, side-load stress on the rod bearing is minimal, though external guides are still recommended for offset payloads.
For an exact ISO 15552 replacement match, pair this 125mm bore, 80mm stroke, PT G1/2 ported cylinder with your existing FA/FB flange or TC trunnion accessories. The -S magnet option is required if you are utilizing electronic end-of-stroke sensing. Note that this standard cylinder relies on air pressure to hold position; if your system drops pressure, the load will drift. For fail-safe holding, consider the SAIL or BSAI locking variants.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for 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 (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI125 Standard Air Cylinder SAI125X80S FAQ
At 0.5 MPa operating pressure, this 125mm bore cylinder provides 6136N of push force and 5734N of pull force. It can reach up to 11045N push at 0.9 MPa.
Yes. The SAI125X80-S is built to the ISO 15552 standard, making its mounting dimensions fully interchangeable with other ISO 15552 profile cylinders. You can swap it directly using your existing FA flange or TC trunnion mounts.
