This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1150N, 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 SI100X1150N
The AirTAC SI100 Standard Cylinder SI100X1150N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1150N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1150N
The AirTAC SI100X1150N is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel. It delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa, utilizing a G1/2 air port and M20x1.5 rod thread. The direct replacement is the SAI100X1150N, matching the 100mm bore, 1150mm stroke, force, port, and ISO 15552 mounting interface exactly.
The SAI upgrade features a revised piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. This NBR-sealed unit lacks a magnet (-N, no -S), meaning it cannot accept CS1-B/DS1-B sensors. For load holding, note that the cushion only decelerates; use an external rod lock or pilot check valve.

Where the Airtac SI100 Standard Cylinder SI100X1150N Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across 1150mm gaps between conveyor lines using 3927 N of thrust at 0.5 MPa.
Large Press Ejection
Ejects molded or stamped parts from deep press beds, relying on the 36mm adjustable cushions to decelerate at stroke end.
Replacing the Airtac SI100 Standard Cylinder SI100X1150N with the SAI100X1150N
To replace the discontinued SI100X1150N, order the SAI100X1150N. Confirm the ISO 15552 mounting accessory (LB, FA, CA, TC), the G1/2 port, and the NBR seal. Because this is a non-magnetized SKU, it cannot support position sensing. For sizing, the 100mm bore yields 3927 N push at 0.5 MPa; if undersizing, an 80mm bore gives 2513 N. If you need load holding on air loss, the plain cylinder drifts, so specify an external pilot check valve or explore the SAIL or BSAI lock variants. With the 1150mm stroke, external guides are critical to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1150N
- ✓ 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 SI100X1150N FAQ
Yes, the SI100X1150N is discontinued. The direct replacement is the SAI100X1150N. It is dimensionally interchangeable per ISO 15552, keeping the same 100mm bore, 1150mm stroke, 3927 N force, G1/2 port, and mounting interface.
The G1/2 port supplies a push force of 3927 N and pull of 3681 N at 0.5 MPa. At 0.7 MPa push is 5497 N, and 7068 N at 0.9 MPa. The theoretical maximum is 801 kgf at 1.0 MPa.
