This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX95, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI100 Standard Cylinder SI100AX95
The AirTAC Airtac SI100 Standard Cylinder SI100AX95 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 95mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX95, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX95
The AirTAC SI100AX95 is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 95 mm stroke. Delivering 3927 N push force at 0.5 MPa through a G1/2 port, it is replaced by the SAI100AX95 direct. This upgrade retains identical mounting and force but adds a two Y-shaped one-way piston seal for low start-up pressure. The -A suffix specifies a SUS420J2 stainless steel rod for corrosion resistance. Lacking the -S magnet, this SKU cannot accept position switches.
The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the legacy line. Note that a standard cylinder drifts without live air; the cushion only decelerates.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100AX95 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100AX95 Is Used
Heavy Press Clamping
Secures large metal castings during machining operations, utilizing the 3927 N push force at 0.5 MPa to prevent workpiece shifting under high tooling loads.
Pallet Diverting
Actuates heavy-duty routing gates on automated packaging lines, where the 95 mm stroke provides rapid and reliable redirection of fully loaded product pallets.
Replacing the Airtac SI100 Standard Cylinder SI100AX95 with the SAI100AX95
To replace the SI100AX95, order the SAI100AX95. Verify the ISO 15552 mounting interface, 100 mm bore, 95 mm stroke, G1/2 port, and M20x1.5 rod thread. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped version if sensing is needed. The -A rod is SUS420J2 stainless steel. If downsizing, an 80 mm bore yields 2513 N push at 0.5 MPa; if upsizing, a 125 mm bore provides 6136 N. For load holding on air loss, the cushion only decelerates; use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX95
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100AX95 FAQ
Yes, the AirTAC SI100AX95 is discontinued. The direct replacement is the SAI100AX95. It is dimensionally interchangeable per ISO 15552, retaining the same 100 mm bore, 95 mm stroke, G1/2 port, and mounting interface.
This double-acting cylinder features a G1/2 port. At 0.5 MPa it provides 3927 N push and 3681 N pull force. At 0.7 MPa push is 5497 N, and at 0.9 MPa push is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
