This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X110S, 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 SI100X110S
The AirTAC Airtac SI100 Standard Cylinder SI100X110S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 110mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X110S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X110S
The AirTAC SI100X110S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 110mm stroke. It delivers 3927N push and 3681N pull at 0.5MPa via a G1/2 port. The direct replacement is the SAI100X110S, matching the interface, force, and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. It adds SAIL, SAIF, and BSAI variants the SI lacked. Rod options include SUS304, and Viton H seals raise heat to 150C.

Where the Airtac SI100 Standard Cylinder SI100X110S Is Used
Heavy Press Clamping
Ideal for exerting high clamping force on large metal fabrications, utilizing the 3927N push force at 0.5MPa to hold parts securely during machining or welding operations.
Pallet Lift Stations
Provides reliable vertical lifting for heavy loaded pallets up to 200kg, where the 110mm stroke precisely indexes goods to the next conveyor tier without overshooting.
Automated Forming Dies
Drives large pneumatic forming dies in stamping lines, benefiting from the adjustable 36mm air cushions at both ends to smoothly decelerate the 25mm rod under high kinetic loads.
Replacing the Airtac SI100 Standard Cylinder SI100X110S with the SAI100X110S
To replace the SI100X110S, order the SAI100X110S. Verify the ISO 15552 mounting interface, 110mm stroke, G1/2 port (PT/G/NPT), and the -S magnet for CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). If sizing up or down, neighbouring bores are 80mm (2513N push) and 125mm (6136N push). For load holding, note that a plain cylinder drifts on air loss as the cushion only decelerates; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. Since 110mm is under 300mm, side-load rod bending is minimal.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X110S
- ✓ 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 SI100X110S FAQ
Yes, the AirTAC SI100X110S is discontinued. The direct replacement is the SAI100X110S. It is dimensionally interchangeable per ISO 15552, retaining the exact same 100mm bore, 110mm stroke, G1/2 port, and mounting accessories for a direct fixture swap.
The bore is 100mm with a G1/2 air port. The thrust is 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical maximum of 801kgf at 1.0MPa. It operates at 30-800mm/s.
