About the Airtac SAI100 Standard Air Cylinder SAI100X140
The AirTAC SAI100X140 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It features a 100mm bore and a 140mm stroke, delivering a robust 3927 N of push force at 0.5 MPa. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that seamlessly drops into existing ISO 15552 mounting interfaces.
This specific configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because a magnet is not specified, it operates without electronic position sensing, relying instead on its adjustable air cushions at both ends to decelerate heavy loads smoothly.

Where the Airtac SAI100 Standard Air Cylinder SAI100X140 Is Used
Heavy Stamping Press
Provides the high push force required to actuate heavy stamping and forming presses in metal fabrication lines.
Pallet Diverting
Drives robust diverters and sorting gates on high-mass pallet conveyors where 3927 N of thrust ensures positive engagement.
Large Component Lift
Lifts substantial automotive subassemblies or heavy molds, utilizing the 140mm stroke for precise vertical positioning.
Is the Airtac SAI100 Standard Air Cylinder SAI100X140 the Right Cylinder?
Selecting this 100mm bore over the smaller 80mm variant significantly increases your thrust capacity, jumping from 2513 N to 3927 N at 0.5 MPa. If your application requires less force, stepping down to the 80mm bore saves space and air consumption. Conversely, if you need to hold a load vertically without continuous air pressure, remember that a standard SAI cylinder will drift; you should upgrade to the SAIL variant with an air-released lock or use an external pilot-operated check valve.
When replacing a cylinder on existing equipment, ensure your mounting accessories match the ISO 15552 footprint. This SAI100X140 uses a G1/2 port, M20x1.5 rod thread, and can be paired with FA or FB flange mounts, TC trunnions, or LB foot brackets depending on your load orientation.
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 SAI100X140 FAQ
At a standard 0.5 MPa operating pressure, the SAI100X140 generates 3927 N of push force and 3681 N of pull force. If you increase the pressure to 0.7 MPa, the push force reaches 5497 N.
Yes. The SAI100X140 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 standard cylinders from brands like Festo or SMC, provided your port and mounting dimensions match.
