About the Airtac SAI125 Standard Air Cylinder SAI125AX110S
The AirTAC SAI125X110-S is a double-acting ISO 15552 profile cylinder featuring a 125mm bore and a 110mm stroke. Because 110mm is not a standard catalog increment, this specific stroke is manufactured as a made-to-order unit. It delivers a robust 6136N push force and 5734N pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks.
This variant is built with a SUS420J2 stainless steel piston rod (material code A), offering excellent corrosion resistance for harsh industrial environments. Equipped with a magnet (-S), it integrates seamlessly with CMSE and DMSE sensor switches housed in the dual-side grooves of the extruded aluminum barrel. Fluid supply is via PT tapered ports sized at G1/2.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX110S Is Used
Heavy Machinery Clamping
Provides the 6136N force required to hold large steel fabrications securely in place during heavy milling or welding operations.
Automated Pressing
Ideal for pressing bearings or bushings into housings, where the 110mm stroke offers precise travel and the SUS420J2 rod withstands repetitive stress.
Bulk Material Diverting
Powers heavy-duty diverters on aggregate or bulk material conveyor lines, using the integrated magnet and CMSE sensors to confirm stroke position.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX110S the Right Cylinder?
Select this 125mm bore when a 100mm bore (offering 3927N push at 0.5 MPa) is insufficient for your load, but you want to avoid the larger footprint and air consumption of a 160mm bore. The 110mm stroke is optimal for applications requiring short, powerful movements where standard 100mm or 125mm strokes do not perfectly fit the machine envelope.
As a genuine ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 125mm bore, 110mm stroke cylinder with a G1/2 port and standard mounting accessories like FA/FB flanges or TC trunnions. Note that the standard SAI does not hold loads when air pressure is removed; for fail-safe holding, consider the SAIL or BSAI variant. Operating speed ranges from 30-500 mm/s.
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 SAI125AX110S FAQ
At a 0.5 MPa operating pressure, the SAI125X110-S generates a push force of 6136N and a pull force of 5734N. At 0.7 MPa, the push force increases to 8590N.
Yes, the SAI125X110-S is dimensionally interchangeable per ISO 15552. You can use it as a drop-in replacement for other ISO 15552 profile cylinders with a 125mm bore, 110mm stroke, and G1/2 PT ports, using standard mounting accessories.
