This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X262SN, 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 SI100X262SN
The AirTAC Airtac SI100 Standard Cylinder SI100X262SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 262mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X262SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X262SN
The AirTAC SI100X262SN is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore, 262mm non-standard stroke, and NBR seals. It delivers a push force of 3927 N at 0.5 MPa. The direct replacement is the SAI100X262SN, sharing the same G1/2 port, M20x1.5 rod thread, and mounting interface. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
Because the stroke is 262mm, this is a non-standard length requiring confirmation from datasheet availability. The built-in magnet (-S) supports legacy CS1-B/DS1-B sensors, while the SAI family uses current AirTAC switches. The SAI line also introduces lock and valve variants the SI lacked, such as the SAIL, SAIF, and BSAI models. Operating temperature is -20 to +70 C, or up to 150 C with a Viton H seal upgrade.

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 SI100X262SN Is Used
Heavy Press Clamping
Secures large metal castings during machining operations, utilizing the 3927 N push force at 0.5 MPa to hold components firmly against the fixture bed.
Logistics Diverters
Drives robust sorting arms on high-throughput packaging lines, moving heavy cartons laterally with a 262mm stroke and adjustable end cushions.
Replacing the Airtac SI100 Standard Cylinder SI100X262SN with the SAI100X262SN
To replace the discontinued SI100X262SN, order the SAI100X262SN direct. Confirm the ISO 15552 mounting interface (LB, FA, TC, etc.), the G1/2 port, and the NBR (-N) seal. The magnet (-S) maps to current AirTAC switches. Sizing both ways: a neighbouring 80mm bore yields 2513 N push at 0.5 MPa, while a 125mm bore yields 6136 N. This 100mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, peaking at 801 kgf at 1.0 MPa. At 262mm stroke, watch for side-load and rod-bending; use a guide to prevent jamming. A plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X262SN
- ✓ 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 SI100X262SN FAQ
Yes, the AirTAC SI100X262SN is discontinued. The direct replacement is the SAI100X262SN. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 262mm stroke, G1/2 port, and mounting interface.
The G1/2 port bore delivers a push force of 3927 N and a 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 max force is 801 kgf at 1.0 MPa.
