About the Airtac SAI100 Standard Air Cylinder SAI100AX70
The AirTAC SAI100X70 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a push force of 3927 N at 0.5 MPa, making it well-suited for high-load clamping and pressing over a 70 mm stroke. The extruded aluminum barrel omits tie rods, providing a clean exterior that resists contamination.
This specific configuration features a SUS420J2 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet, focusing entirely on pure mechanical thrust. The extruded barrel includes sensor grooves on both sides, allowing for future position monitoring upgrades if needed.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX70 Is Used
Heavy-Duty Stamping
Provides the robust 3927 N push force required to seat bearings or stamp metal components in automated presses.
Pallet Stopping
Acts as a high-force stopper mechanism on heavy-load conveyor lines, absorbing significant kinetic energy.
Material Clamping
Secures large workpieces or heavy castings during CNC machining or welding operations with unwavering rigidity.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX70 the Right Cylinder?
If an application requires slightly less force, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa. For greater thrust, the 125 mm variant provides 6136 N. Because the 70 mm stroke is relatively short, side-load stress on the rod bearing is minimal. However, this standard cylinder cannot hold a load if air pressure is lost; for position holding without live pressure, consider the SAIL locking variant or an external rod lock. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 100 mm bore, 70 mm stroke ISO 15552 unit using PT ports and standard FA or FB flange mounts.
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 SAI100AX70 FAQ
At a 0.5 MPa operating pressure, the SAI100X70 generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X70 is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other standard ISO 15552 cylinders of the same bore and stroke, provided your setup accommodates PT tapered ports.
