This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX700, 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 SI100AX700
The AirTAC Airtac SI100 Standard Cylinder SI100AX700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX700
The AirTAC SI100AX700 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 700mm stroke. It delivers 3927 N push force at 0.5 MPa and features a SUS420J2 stainless piston rod for corrosion resistance. Because this legacy unit is end-of-life, you should order the direct replacement: the SAI100AX700. It maintains the identical ISO 15552 mounting interface, G1/2 port, and output force.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Without a -S suffix, this SKU cannot take a magnetic switch. Note that a plain cylinder drifts on air loss; use a SAIL lock or external pilot check valve to hold loads.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100AX700 Is Used
Large Press Ejection
Provides the 3927 N push at 0.5 MPa needed to eject heavy stamped parts from a press bed over a 700mm reach.
Pallet Pusher Unit
Moves loaded pallets along a roller conveyor, utilizing the 100mm bore's 200 kg safe vertical lift equivalent for heavy goods.
Material Lift Station
Raises heavy material racks using the SUS420J2 stainless rod to resist moisture, requiring external guides to manage the 700mm stroke.
Replacing the Airtac SI100 Standard Cylinder SI100AX700 with the SAI100AX700
To replace the discontinued SI100AX700, order the SAI100AX700. Verify your ISO 15552 mounting interface (LB, FA, TC, etc.), the 700mm stroke, and the G1/2 port. This unit has an M20x1.5 rod thread and a SUS420J2 stainless rod. Because it lacks the -S magnet, it cannot accept CS1-B/DS1-B sensors. If dropping to 80mm is insufficient, keep the 100mm. For load holding on air loss, the cushion only decelerates; add a SAIL lock, BSAI clamp-lock, or external pilot check valve. At 700mm stroke, prevent rod bending by guiding the load externally to avoid side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX700
- ✓ 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 SI100AX700 FAQ
Yes, the SI100AX700 is discontinued. The direct replacement is the SAI100AX700. It is dimensionally interchangeable per ISO 15552, keeping the same 100mm bore, 700mm stroke, G1/2 port, and mounting interface.
This cylinder uses a G1/2 air port. It generates 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa.
