This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX195S, 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 SI100AX195S
The AirTAC Airtac SI100 Standard Cylinder SI100AX195S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 195mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX195S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX195S
The AirTAC SI100AX195S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 195mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100AX195S, matching the interface, stroke, force, and mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. The SAI family adds SAIL, SAIF, and BSAI lock variants. This -A variant uses a SUS420J2 stainless rod. Note that 195mm is a nonstandard stroke.

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 SAI100AX195S 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 SI100AX195S Is Used
Heavy-Duty Pressing
Drives large stamps and forms requiring high force, using the 3927 N push at 0.5 MPa to seat components reliably.
Corrosive Material Handling
Uses the SUS420J2 stainless rod option to actuate damp or chemically exposed gates without surface degradation.
Replacing the Airtac SI100 Standard Cylinder SI100AX195S with the SAI100AX195S
To replace the SI100AX195S, order the SAI100AX195S. Confirm the ISO 15552 mounting interface, the G1/2 port, the M20x1.5 rod thread, and the -S magnet for current AirTAC switches (legacy used CS1-B/DS1-B). The -A code specifies the SUS420J2 stainless rod over standard carbon steel. If sizing up or down, neighboring bores are 80mm and 125mm; at 0.5 MPa this 100mm bore gives 3927 N push and 3681 N pull. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for holding. For self-contained locking, consider the SAIL or BSAI variants. Since the 195mm stroke is nonstandard, verify cushion adjustment. For any stroke over 300mm, guide the load to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX195S
- ✓ 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 SI100AX195S FAQ
Yes, the SI100AX195S is discontinued. The direct replacement is the SAI100AX195S. It is dimensionally interchangeable per ISO 15552, keeping the same 100mm bore, 195mm stroke, G1/2 port, and mounting fixtures.
This double-acting cylinder uses a G1/2 air port. At 0.5 MPa it pushes 3927 N and pulls 3681 N. At 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical max force is 801 kgf at 1.0 MPa.
