This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X860S, 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 SI100X860S
The AirTAC Airtac SI100 Standard Cylinder SI100X860S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 860mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X860S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X860S
The AirTAC SI100X860S is a discontinued double-acting ISO 15552 profile cylinder with a 100 mm bore and 860 mm stroke. It delivers a push force of 3927 N at 0.5 MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X860S, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, and output force.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. For applications needing load holding on air loss, the SAI family introduces SAIL 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 SI100X860S Is Used
Heavy Material Transfer
Pushes loaded pallets or heavy workpieces along a conveyor line using its 3927 N thrust at 0.5 MPa.
Large Press Ejection
Provides the long 860 mm reach and 7068 N force at 0.9 MPa needed to eject bulky formed parts from machinery.
Replacing the Airtac SI100 Standard Cylinder SI100X860S with the SAI100X860S
To replace the SI100X860S, order the SAI100X860S. Confirm the ISO 15552 mounting accessory (LB, FA, CA, TC), the G1/2 port thread (PT, G, or NPT), and the -S magnet for CS1-B/DS1-B legacy sensors. The SAI uses current AirTAC switches. If sizing down, a 80 mm bore yields 2513 N push at 0.5 MPa; sizing up to 125 mm provides 6136 N. Note that an 860 mm stroke requires external guides to prevent rod bending under side loads. A plain cylinder drifts without live air; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X860S
- ✓ 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 SI100X860S FAQ
Yes, the SI100X860S is discontinued. The direct replacement is the SAI100X860S. It shares the identical ISO 15552 mounting interface, 100 mm bore, 860 mm stroke, output force, and G1/2 port, fitting directly into existing fixtures.
It features a G1/2 air port and delivers a push force of 3927 N and pull of 3681 N at 0.5 MPa. At 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
