This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X230SCB, 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.

The AirTAC Airtac SI100 Standard Cylinder SI100X230SCB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 230mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X230SCB, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SI100X230SCB is a discontinued double-acting ISO 15552 profile cylinder featuring a 100mm bore and 230mm stroke. It delivers 3927N push force at 0.5MPa, uses a G1/2 port, and includes a CB clevis mount with a piston magnet for CS1-B/DS1-B switches. AirTAC replaced this legacy unit with the SAI100X230SCB, a direct replacement sharing the exact ISO 15552 mounting interface, bore, stroke, force, and port size.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. It also adds SAIL, SAIF, and BSAI lock variants the SI line lacked. Note that 230mm is a nonstandard stroke length.

Legacy SI-family variants: SID (double rod), SIJ (adjustable stroke) — each maps to its SAI equivalent (SID→SAID, SIJ→SAIJ). Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B).
Ideal for positioning heavy metal stampings into press fixtures, utilizing the 3927N push force to seat components firmly before the main ram cycles.
Deploys a 230mm stroke to actuate heavy-duty stop gates on conveyor lines, securely halting loaded pallets up to 200kg in vertical lift scenarios.
Leverages the CB clevis mount to swing large molding tooling into place, taking advantage of the 7068N push force available at 0.9MPa for rigid holding.
To replace the SI100X230SCB, order the SAI100X230SCB. Confirm the ISO 15552 CB clevis mounting, G1/2 port, and the -S magnet for legacy CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). For sizing, the neighboring 80mm bore yields 2513N push at 0.5MPa, while the 125mm bore yields 6136N; this 100mm bore gives 3927N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify an SAIL/BSAI lock variant. Since 230mm is nonstandard and over 200mm, ensure guide rails prevent rod bending under side loads.
Replacement checklist
Yes, the SI100X230SCB is discontinued. The direct replacement is the SAI100X230SCB. It shares the identical ISO 15552 mounting interface, 100mm bore, 230mm stroke, output force, and G1/2 port, fitting directly into existing CB clevis fixtures.
It features a G1/2 port. The force ratings are: 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa. Operating speed is 30-800mm/s.
