This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X200, 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 SI100X200
The AirTAC Airtac SI100 Standard Cylinder SI100X200 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 SAI100X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X200
The AirTAC SI100X200 is a discontinued double-acting ISO 15552 profile cylinder, delivering a push force of 3927 N and pull of 3681 N at 0.5 MPa through its 100 mm bore. It features a 25 mm carbon steel piston rod, M20x1.5 thread, and a G1/2 air port. AirTAC replaced this legacy unit with the SAI100X200, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, and port size.
The SAI100X200 introduces an upgraded piston seal utilizing two Y-shaped one-way elements for extended life and lower start-up pressure. Because this specific SI SKU lacks the -S magnet suffix, it cannot accept position sensors like the legacy CS1-B or DS1-B switches.

Where the Airtac SI100 Standard Cylinder SI100X200 Is Used
Heavy Stamping Press
Drives large platens and stamping dies requiring high thrust, utilizing the 5497 N output at 0.7 MPa to form thick gauge materials reliably.
Pallet Diversion
Actuates heavy-duty lane diverters and sorting gates on high-capacity packaging lines, moving loaded pallets with a 200 kg vertical lift equivalence.
Automated Guided Vehicles
Raises and lowers substantial lifting forks on automated guided vehicles, depending on the 25 mm rod and robust profile barrel for rigid load transfer.
Replacing the Airtac SI100 Standard Cylinder SI100X200 with the SAI100X200
To replace the discontinued SI100X200, order the SAI100X200 direct equivalent, confirming the ISO 15552 mounting interface, 100 mm bore, 200 mm stroke, and G1/2 port (available in PT, G, or NPT threads). Since this original SKU has no -S magnet, it cannot support sensing; if switches are needed, specify an SAI100X200S. For sizing alternatives, dropping to an 80 mm bore reduces the 0.5 MPa push force to 2513 N, while stepping up to 125 mm increases it to 6136 N. Note that a plain cylinder drifts on air loss and the air cushions only decelerate near stroke end; for load holding, consider the SAIL air-released lock, the BSAI clamp-lock variant, or an external pilot check valve. The 36 mm adjustable cushions suit this 200 mm stroke well.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X200
- ✓ 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 SI100X200 FAQ
Yes, the AirTAC SI100X200 is discontinued. The direct replacement is the SAI100X200. It shares the identical ISO 15552 mounting interface, 100 mm bore, 200 mm stroke, output force, and G1/2 port, fitting existing fixtures perfectly while adding an upgraded piston seal.
The 100 mm bore features a G1/2 air port and provides a push force of 3927 N and pull of 3681 N at 0.5 MPa. At 0.7 MPa the push force is 5497 N, reaching 7068 N at 0.9 MPa. The theoretical maximum force is 801 kgf at 1.0 MPa.
