About the Airtac SAI100 Standard Air Cylinder SAI100X140S
The AirTAC SAI100X140-S is a double-acting ISO 15552 profile cylinder engineered to deliver a substantial push force of 3927 N and a pull force of 3681 N at 0.5 MPa. Featuring a 100mm bore and a 140mm stroke, it is built for heavy-duty automation tasks requiring significant linear thrust. The extruded aluminum barrel design ensures structural rigidity while keeping the assembly lightweight.
This specific configuration includes an integrated magnet (-S) for seamless compatibility with CMSE and DMSE reed switches, which mount directly into the dual sensor grooves on the barrel. The standard piston rod is constructed from durable carbon steel, and users can select alternative seal materials like NBR or high-temperature Viton (H) to match specific environmental demands.

Where the Airtac SAI100 Standard Air Cylinder SAI100X140S Is Used
Heavy-Duty Pressing
Generates 5497 N of push force at 0.7 MPa, making it ideal for metal forming, riveting, and heavy assembly press operations within a 140mm travel range.
Automated Clamping
Provides robust, secure holding power for large automotive components or heavy machined parts during CNC machining and welding processes.
Pallet Handling
Delivers the high thrust required to lift, push, and position heavy loaded pallets or industrial totes on conveyor lines with reliable speed.
Is the Airtac SAI100 Standard Air Cylinder SAI100X140S the Right Cylinder?
If your application requires less force, stepping down to the 80mm bore variant yields 2513 N of push force at 0.5 MPa, while moving up to the 125mm bore provides 6136 N for heavier loads. The 140mm stroke is well-suited for compact, high-impact pressing or clamping operations.
Because this is a standard double-acting cylinder, it relies on continuous air pressure to hold position; if air is exhausted or the valve is centered, the piston will drift. For applications that must maintain a load under lost pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a true ISO 15552 profile cylinder, this unit serves as a drop-in replacement for any standard ISO 15552 mounting interface, utilizing a G1/2 port, a PT tapered thread type, and compatible FA/FB flange or TC trunnion accessories.
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 SAI100 Standard Air Cylinder SAI100X140S FAQ
At an operating pressure of 0.5 MPa, the SAI100X140-S cylinder provides a push (extend) force of 3927 N and a pull (retract) force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X140-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions and interface are fully interchangeable with other standard ISO 15552 cylinders of the same bore size.
