This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X313S, 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 SI100X313S
The AirTAC SI100 Standard Cylinder SI100X313S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 313mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X313S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X313S
The AirTAC SI100X313S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 313mm stroke. It delivers 3927 N push and 3681 N pull at 0.5 MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X313S, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, force, and port size.
The SAI replacement features an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces SAIL, SAIF, and BSAI lock variants absent in the SI line. This -S SKU includes a magnet for CS1-B/DS1-B sensors.

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 SI100X313S Is Used
Heavy Press Clamping
Applies up to 7068 N of clamping force at 0.9 MPa to secure heavy metal castings during CNC machining operations.
Long Stroke Diversion
Uses the 313mm stroke to push heavy product bundles across wide conveyor belts during automated sortation.
Replacing the Airtac SI100 Standard Cylinder SI100X313S with the SAI100X313S
To replace the SI100X313S, order the SAI100X313S and confirm the ISO 15552 mounting interface, 313mm stroke, and G1/2 port (PT/G/NPT). Retain your original mounting accessory (LB, FA, TC, etc.) and the -S magnet for current AirTAC switches. Sizing both ways: the neighboring 80mm bore yields 2513 N [email protected], while the 125mm bore yields 6136 N. This 100mm bore provides 3927 N push and 7068 N at 0.9 MPa. Because the 313mm stroke exceeds 300mm, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; for load holding, specify the SAIL or BSAI lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X313S
- ✓ 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 SI100X313S FAQ
Yes, the SI100X313S is discontinued. The direct replacement is the AirTAC SAI100X313S. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 313mm stroke, output force, G1/2 port, and mounting interface.
The G1/2 port supplies a 25mm rod. At 0.5 MPa it provides 3927 N push and 3681 N pull. 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.
