This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100AX220, 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 SI100AX220
The AirTAC Airtac SI100 Standard Cylinder SI100AX220 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 220mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100AX220, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100AX220
The AirTAC SI100AX220 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 220mm stroke. It delivers 3927N push and 3681N pull at 0.5MPa via a G1/2 port. The direct replacement is the SAI100AX220, which shares identical ISO 15552 mounting, force, and dimensions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and longevity. This SKU lacks a magnet, so it cannot take a CS1-B/DS1-B sensor. The -A rod is SUS420J2 stainless steel; Viton H seals raise heat to 150C.

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

Where the Airtac SI100 Standard Cylinder SI100AX220 Is Used
Heavy-Duty Pressing
Drives large stamping and forming presses requiring 3927N of push force at 0.5MPa with stable 220mm travel.
Pallet Diversion
Actuates heavy lane diverters and sorting gates on high-capacity conveyor lines handling substantial loads.
Replacing the Airtac SI100 Standard Cylinder SI100AX220 with the SAI100AX220
To replace the SI100AX220, order the SAI100AX220. Verify the ISO 15552 interface, 220mm stroke, G1/2 port, and SUS420J2 stainless rod. Since this SKU lacks a magnet (-S), it cannot accept position sensors. If sizing down, the 80mm bore yields 2513N push at 0.5MPa; sizing up to 125mm provides 6136N. For loads over 220mm, add external guides to prevent rod bending. The cushion only decelerates; it does not hold load on air loss. For secure holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100AX220
- ✓ 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 SI100AX220 FAQ
Yes, the SI100AX220 is discontinued. The direct replacement is the SAI100AX220. It features the same ISO 15552 mounting interface, 100mm bore, 220mm stroke, G1/2 port, and output force, fitting existing fixtures perfectly.
This double-acting cylinder uses a G1/2 port. The thrust is 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical maximum of 801kgf at 1.0MPa.
