This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X200N, 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 SI100X200N
The AirTAC Airtac SI100 Standard Cylinder SI100X200N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 200mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X200N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X200N
The AirTAC SI100X200N is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore and 200mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X200N, a direct upgrade retaining the exact mounting interface, bore, stroke, output force, and port size.
The SAI successor features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. It also introduces SAIL, SAIF, and BSAI lock variants absent in the SI line. This NBR-sealed SKU (-N) operates from -20 to +70 C, and because it lacks the -S magnet, it cannot accept position sensors.

Where the Airtac SI100 Standard Cylinder SI100X200N Is Used
Heavy Press Clamping
Ideal for exerting high clamping force on large metal fabrications, utilizing the 3927 N push force to secure heavy parts during machining or welding operations.
Pallet Diverting
Provides robust actuation for heavy-duty material handling systems, easily shifting loaded pallets across conveyor lanes with a 200 mm stroke.
Large Door Actuation
Delivers reliable linear motion for opening and closing substantial industrial access doors or safety gates where substantial thrust is consistently required.
Replacing the Airtac SI100 Standard Cylinder SI100X200N with the SAI100X200N
To replace the discontinued SI100X200N, order the SAI100X200N. Confirm the ISO 15552 mounting interface, 100mm bore, 200mm stroke, G1/2 port (PT/G/NPT thread options), and your specific mounting accessory (LB, FA, CA, TC, etc.). This SKU lacks the -S magnet, so it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, switch to a current SAI switch with an -S magnet model. For sizing, the 100mm bore yields 3927 N push at 0.5 MPa; if less force is needed, an 80mm bore provides 2513 N, while a 125mm bore offers 6136 N. Remember, a standard cylinder does not hold load without live air—the cushion only decelerates. For load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X200N
- ✓ 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 SI100X200N FAQ
Yes, the AirTAC SI100X200N is discontinued. The direct replacement is the SAI100X200N. It features the same ISO 15552 mounting interface, 100mm bore, 200mm stroke, output force, and G1/2 port, fitting directly into existing fixtures.
This double-acting cylinder uses a G1/2 air port. At 0.5 MPa it provides 3927 N push and 3681 N pull force. At 0.7 MPa push is 5497 N, and at 0.9 MPa it is 7068 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
