This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X332S, 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 SI100X332S
The AirTAC Airtac SI100 Standard Cylinder SI100X332S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 332mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X332S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X332S
The AirTAC SI100X332S is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel. In this 100 mm bore class it delivers 3927 N of push force at 0.5 MPa through a G1/2 port. AirTAC replaced the SI line with the SAI family; the direct replacement is the SAI100X332S, retaining the same stroke, output force, port size and mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. For applications needing load holding on air loss, the SAI family adds the SAIL air-released lock and BSAI clamp-lock variants the SI lacked. The -S suffix on this SKU indicates a piston magnet for legacy CS1-B/DS1-B sensors; the SAI replacement uses current AirTAC switches.

Where the Airtac SI100 Standard Cylinder SI100X332S Is Used
Heavy Material Transfer
Drives robust pallet stops and heavy product diverters on high-throughput packaging lines requiring the full 3927 N push force at 0.5 MPa.
Large Press Ejection
Ejects formed metal or composite parts from large press beds, utilizing the 100 mm bore's 801 kgf maximum theoretical output at 1.0 MPa.
Replacing the Airtac SI100 Standard Cylinder SI100X332S with the SAI100X332S
To replace the SI100X332S, order the SAI100X332S. Verify your ISO 15552 mounting interface, the G1/2 air port, and your PT/G/NPT thread preference. The M20x1.5 rod end and 36 mm adjustable cushions carry over directly. Because this is a 332 mm stroke, use an external guide to prevent rod bending and side-load damage. A plain cylinder drifts on air loss—the cushions only decelerate near stroke end—so for load holding specify an external rod lock, a pilot check valve, or the SAIL/BSAI lock variant. If you need more force, the 125 mm bore offers 6136 N push at 0.5 MPa; if less is acceptable, the 80 mm bore provides 2513 N. The magnet (-S) supports CS1-B/DS1-B switches, while the SAI uses current switches.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X332S
- ✓ 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 SI100X332S FAQ
Yes, the SI100X332S is discontinued. The direct replacement is the AirTAC SAI100X332S. It is dimensionally interchangeable per ISO 15552, matching the 100 mm bore, 332 mm stroke, G1/2 port, and mounting fixtures, but features an upgraded two Y-shaped one-way piston seal.
The 100 mm bore operates at 30-800 mm/s. Force output is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa.
