This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X110, 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 SI100X110
The AirTAC Airtac SI100 Standard Cylinder SI100X110 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 110mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X110, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X110
The AirTAC SI100X110 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 110mm stroke. It delivers 3927 N push force at 0.5 MPa via a G1/2 port. AirTAC replaced this legacy unit with the SAI100X110, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, force, port and mounting hardware.
The SAI100X110 features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For sensing, this specific no-S SKU cannot take a magnetic switch (legacy CS1-B/DS1-B sensors require the -S option). The SAI family also adds SAIL, SAIF and BSAI lock variants the SI lacked.

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 SI100X110 Is Used
Heavy-Duty Pressing
Drives large stamping and forming dies requiring substantial thrust, utilising the 5497 N push force available at 0.7 MPa.
Pallet Diversion
Actuates heavy lane guides and diverters on packaging lines, moving loaded pallets with a 200 kg vertical lift margin.
Material Lift Gates
Raises and lowers industrial safety gates or heavy access doors, relying on the 36mm adjustable air cushions for smooth deceleration.
Replacing the Airtac SI100 Standard Cylinder SI100X110 with the SAI100X110
To replace the SI100X110, order the SAI100X110. Confirm the ISO 15552 mounting interface, 100mm bore, 110mm stroke, G1/2 port (PT/G/NPT thread options) and your mounting accessory (LB, FA, TC, etc.). This no-S SKU lacks a magnet and cannot accept a sensor; if you need position detection, switch to an SAI100X110S. Sizing both ways: neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while the 125mm bore yields 6136 N. 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. Since this stroke is under 300mm, rod-bending side-load risks are minimal, but always guide the load.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X110
- ✓ 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 SI100X110 FAQ
Yes, the AirTAC SI100X110 is discontinued. The direct replacement is the SAI100X110. It shares the identical ISO 15552 mounting interface, 100mm bore, 110mm stroke, output force, G1/2 port and mounting accessories, fitting directly into existing fixtures.
The G1/2 port bore delivers a push of 3927 N and pull of 3681 N 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. It operates at 30-800 mm/s with a 25mm rod and M20x1.5 thread.
