This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X220S, 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 SI100X220S
The AirTAC Airtac SI100 Standard Cylinder SI100X220S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 220mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X220S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X220S
The AirTAC SI100X220S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 220mm stroke. It delivers 3927N push force at 0.5MPa via a G1/2 port. The direct replacement is the SAI100X220S, matching the exact ISO 15552 mounting interface, bore, stroke, force and port size.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family adds SAIL, SAIF and BSAI lock variants the SI lacked. This -S SKU has a magnet for CS1-B/DS1-B sensors.

Where the Airtac SI100 Standard Cylinder SI100X220S Is Used
Heavy-Duty Pressing
Applies the 5497N push force at 0.7MPa to seat bearings and assemble heavy mechanical components securely.
Pallet Diversion
Uses the 220mm stroke to push loaded pallets onto secondary packaging lines without external guides.
Replacing the Airtac SI100 Standard Cylinder SI100X220S with the SAI100X220S
To replace the SI100X220S, order the SAI100X220S. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G1/2 port thread (PT/G/NPT) and the -S magnet. The 220mm stroke is nonstandard (exceeding the 200mm standard increment), so confirm exact dimensions. For sizing, a 100mm bore yields 3927N push at 0.5MPa; dropping to an 80mm bore gives 2513N, while a 125mm bore provides 6136N. Since 220mm exceeds 300mm guidelines, ensure adequate guide support to prevent rod bending. A plain cylinder drifts without air; for load holding use the SAIL or BSAI lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X220S
- ✓ 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 SI100X220S FAQ
Yes, the SI100X220S is discontinued. The direct replacement is the SAI100X220S. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 220mm stroke, force, G1/2 port and mounting interface.
The bore is 100mm with a G1/2 port. At 0.5MPa it provides 3927N push and 3681N pull force. At 0.7MPa push is 5497N, at 0.9MPa it is 7068N, and the theoretical maximum is 801kgf at 1.0MPa.
