This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X220, 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 SI100X220
The AirTAC Airtac SI100 Standard Cylinder SI100X220 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 SAI100X220, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X220
The AirTAC SI100X220 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 220mm stroke, delivering 3927N push and 3681N pull at 0.5MPa through its G1/2 port. AirTAC replaced this legacy unit with the SAI100X220. This direct successor maintains the exact ISO 15552 mounting interface, bore, stroke, force, port and accessories, fitting existing fixtures perfectly.
The SAI100X220 upgrade features a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SI SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors. The SAI family also introduces SAIL, SAIF and BSAI lock variants absent in the SI line.

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 SI100X220 Is Used
Heavy-Duty Pressing
Ideal for applying high clamp force in assembly jigs, utilizing the 3927N push at 0.5MPa to seat bearings or form components reliably.
Automated Forming
Powers large-scale forming and stamping stations where the 100mm bore and 220mm stroke provide the necessary reach and thrust.
Replacing the Airtac SI100 Standard Cylinder SI100X220 with the SAI100X220
To replace the SI100X220, order the SAI100X220. Verify your ISO 15552 mounting interface (LB, FA, TC, etc.), the 220mm stroke, and the G1/2 port (PT/G/NPT threads). Because this SKU lacks a magnet, it cannot support position sensing; if you need switches, select an SAI100X220S and use current AirTAC sensors. For sizing, the 100mm bore yields 3927N push at 0.5MPa; if undersized, the 125mm bore offers 6136N. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. With a 220mm stroke, side-load is minimal, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X220
- ✓ 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 SI100X220 FAQ
Yes, the SI100X220 is discontinued. The direct replacement is the SAI100X220. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 220mm stroke, 3927N force, G1/2 port, and mounting accessories, so it fits existing fixtures directly.
This double-acting cylinder features a G1/2 port and a 25mm rod. It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa. The adjustable air cushion is 36mm at each end.
