This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X263SN, 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 SI100X263SN
The AirTAC Airtac SI100 Standard Cylinder SI100X263SN is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 263mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X263SN, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X263SN
The AirTAC SI100X263SN is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 263mm stroke. It delivers a push force of 3927 N at 0.5 MPa via a G1/2 port. AirTAC replaced this legacy unit with the SAI100X263SN, a direct upgrade sharing the exact ISO 15552 mounting interface, bore, stroke, and force.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The -N suffix denotes NBR seals (-20 to +70 C), though a Viton H option extends this to 150 C. The -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI family also introduces SAIL, SAIF, and BSAI lock variants.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X263SN produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X263SN Is Used
Heavy-Duty Pressing
Applies the 3927 N push force at 0.5 MPa for seating bearings and assembling heavy drivetrain components.
Package Diversion
Actuates large sorting gates and pushers on high-throughput packaging lines with adjustable end cushions.
Replacing the Airtac SI100 Standard Cylinder SI100X263SN with the SAI100X263SN
To replace the discontinued SI100X263SN, order the SAI100X263SN. Confirm the ISO 15552 mounting interface (LB, FA, TC, etc.), the G1/2 port, and the M20x1.5 rod thread. The 263mm stroke is non-standard, so verify fixture clearance. For sizing, this bore pushes 3927 N at 0.5 MPa; if you need less force, step down to an 80mm bore (2513 N), or up to 125mm (6136 N) for more. Because 263mm exceeds 300mm is false here, but always ensure adequate guide support to prevent rod bending. A plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or explore the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X263SN
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
