About the Airtac SAI100 Standard Air Cylinder SAI100AX750
The AirTAC SAI100X750 is a double-acting ISO 15552 profile cylinder offering a robust 3927 N push force at 0.5 MPa. Its 750 mm stroke provides extended travel for demanding positioning tasks. Built with an extruded aluminum barrel, it omits traditional tie-rods for a cleaner exterior while maintaining strict dimensional interchangeability.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid environments. It uses PT tapered port threads and lacks a magnet, meaning it will not directly support reed sensors like the CMSE or DMSE series without modification.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX750 Is Used
Automated Stamping
Provides the 3927 N push force at 0.5 MPa needed to actuate large stamping presses over a 750 mm travel distance.
Material Elevation
Drives extended vertical lifting platforms in packaging lines, utilizing the 750 mm stroke to transfer goods between floor levels.
Large Door Actuation
Opens and closes heavy industrial machine safety doors, relying on the rigid extruded aluminum profile for stable movement.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX750 the Right Cylinder?
If your application requires less push force, stepping down to the 80 mm bore yields 2513 N at 0.5 MPa, while moving up to the 125 mm bore provides 6136 N. Because this 750 mm stroke exceeds the 300 mm threshold, the unsupported rod length is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, mount this cylinder on an external guide rail or utilize a dedicated guided cylinder.
This model is dimensionally interchangeable with other ISO 15552 cylinders. When replacing, match the 100 mm bore, 750 mm stroke, G1/2 PT port, and appropriate mounting accessories like the FA flange or TC trunnion. Note that this standard SAI variant does not hold position automatically upon air loss; if mid-stroke locking is required for safety, consider the SAIL or BSAI variants.
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 SAI100AX750 FAQ
At 0.5 MPa operating pressure, the SAI100X750 generates a push force of 3927 N and a pull force of 3681 N. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X750 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other standard ISO 15552 cylinders of the same 100 mm bore and 750 mm stroke. It is not a direct brand equivalent but matches the mounting interface exactly.
