This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1200SH, 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 SI100X1200SH
The AirTAC SI100 Standard Cylinder SI100X1200SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1200SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1200SH
The AirTAC SI100X1200SH is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore, 1200mm stroke, G1/2 port, and Viton H high-temperature seals (0 to 150 C). Delivering 3927 N push force at 0.5 MPa, its direct replacement is the SAI100X1200SH, which shares the exact same interface, output, and mounting.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and longevity. The SAI family also adds SAIL, SAIF, and BSAI lock variants absent in the SI line. Your -S magnet works with legacy CS1-B/DS1-B sensors.

Where the Airtac SI100 Standard Cylinder SI100X1200SH Is Used
Long-Stroke Ejection
Pushes heavy molded parts or pallets over 1200mm cycles, yielding 3927 N at 0.5 MPa for reliable automated ejection.
High-Temp Pressing
Viton H seals tolerate 0-150 C environments, making it suitable for applying 5497 N at 0.7 MPa in hot-end pressing tasks.
Heavy Material Transfer
Shifts substantial workpieces along production lines, utilizing the G1/2 port and 30-800 mm/s speed for brisk transfers.
Replacing the Airtac SI100 Standard Cylinder SI100X1200SH with the SAI100X1200SH
To replace the SI100X1200SH, order the SAI100X1200SH: it matches the ISO 15552 mounting dimensions, 100mm bore, 1200mm stroke, G1/2 port, and M20x1.5 rod thread. Retain your existing mounting accessories and confirm port threads (PT/G/NPT). At 0.5 MPa it yields 3927 N push and 3681 N pull; if undersized, the 125mm bore offers 6136 N push. Because this is a 1200mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1200SH
- ✓ 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 SI100X1200SH FAQ
Yes, the SI100X1200SH is discontinued. The direct replacement is the SAI100X1200SH. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 1200mm stroke, G1/2 port, and mounting fixtures.
The 100mm bore provides 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N at 0.9 MPa, and a theoretical max of 801 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
