About the Airtac SAI125 Standard Air Cylinder SAI125X1400S
The AirTAC SAI125X1400-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Operating at 0.5 MPa, it generates 6136 N of push force and 5734 N of pull force, making it well-suited for moving substantial masses over extended 1400 mm travels. As a made-to-order non-standard stroke, it provides tailored motion control for specialized machinery.
This variant includes a built-in magnet for seamless position detection using CMSE or DMSE sensor switches along the dual-side barrel grooves. The piston rod is constructed from durable carbon steel, and the adjustable air cushions at both ends deliver 40 mm of cushioning travel to absorb kinetic energy smoothly at high speeds.

Where the Airtac SAI125 Standard Air Cylinder SAI125X1400S Is Used
Automated Press Lines
Provides the robust 6136 N push force needed to actuate large stamping or forming presses over a 1400 mm span.
Material Transfer Arms
Drives long-reach pusher arms on heavy-duty conveyor systems, utilizing adjustable cushions to stop heavy pallets smoothly.
Large Assembly Jigs
Positions heavy structural components during assembly, relying on the -S magnet to trigger CMSE sensors for precise end-of-stroke confirmation.
Is the Airtac SAI125 Standard Air Cylinder SAI125X1400S the Right Cylinder?
If an application requires less thrust, stepping down to the 100 mm bore yields 3927 N of push force at 0.5 MPa, whereas upgrading to the 160 mm bore provides 10053 N for heavier loads. Because this model features a 1400 mm stroke, side load is a primary concern; long unsupported rods are highly susceptible to bending. To prevent premature wear on the rod bearing, implement an external guide rail or utilize a dedicated guided cylinder assembly to support the load laterally.
This unit is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. It utilizes a PT tapered G1/2 port, pairs with TC or LB mounting accessories, and includes the -S magnet option for electronic switching. Remember that standard double-acting cylinders drift when air pressure is removed; for static holding without live pressure, specify the SAIL or BSAI locking variant.
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.
