This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X600S, 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 SI100X600S
The AirTAC Airtac SI100 Standard Cylinder SI100X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 600mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X600S
The AirTAC SI100X600S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 600mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X600S, a direct upgrade sharing the exact ISO 15552 mounting interface, stroke, output force, and accessories.
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 adds SAIL, SAIF, and BSAI lock variants the SI line lacked. Your -S suffix indicates a piston magnet for legacy CS1-B/DS1-B sensors.

Where the Airtac SI100 Standard Cylinder SI100X600S Is Used
Heavy Material Transfer
Drives large pallets or heavy fixtures over 600mm on assembly lines using 3927 N of push force at 0.5 MPa.
Automated Warehousing
Actuates substantial vertical lift gates or heavy-duty diverters requiring a 100mm bore and G1/2 port.
Large Press Ejection
Ejects dense manufactured parts from machinery, utilizing the 600mm stroke to clear the work area completely.
Replacing the Airtac SI100 Standard Cylinder SI100X600S with the SAI100X600S
To replace the SI100X600S, order the SAI100X600S. Verify your ISO 15552 mounting fixtures (LB, FA, TC, etc.), the G1/2 air port, and the M20x1.5 rod thread. The -S magnet enables current AirTAC switches (replacing legacy CS1-B/DS1-B). If you need less force, a 80mm bore yields 2513 N push at 0.5 MPa; if you need more, a 125mm bore yields 6136 N. Because this is a 600mm stroke, use an external guide to prevent rod bending and side-load damage. A plain cylinder drifts without live air; for load holding, use the SAIL or BSAI lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X600S
- ✓ 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 SI100X600S FAQ
Yes, the SI100X600S is discontinued. The direct replacement is the SAI100X600S. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 600mm stroke, force, G1/2 port, and mounting interface.
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 maximum theoretical force of 801 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, speed is 30-800 mm/s, and it uses a G1/2 port.
