This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X200-100S, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X200-100S 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 SAIJ100X200-100S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ100X200-100S is a double-acting, double-rod ISO 15552 adjustable-stroke cylinder with a 100mm bore, G1/2 port, and a 200mm nominal stroke. This discontinued unit is fully replaced by the direct replacement SAIJ100X200-100S, which retains the exact interface, M20x1.5 rod thread, and 36mm adjustable cushions. The external stop screw lets you trim the extend stroke by up to 100mm on-site (yielding a 100-200mm usable range) to dial in end positions without mechanical shims. The stop sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches, while the SAIJ replacement uses current AirTAC switches.

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).
Dialing in a precise press fit by trimming the extend stroke up to 100mm on-site, avoiding hard mechanical shims during assembly line tooling changes.
Adjusting a diverter arm's end position on a conveyor to handle varying package lengths without swapping the entire actuator assembly.
Setting exact push-off distances for different pallet stack heights, using the stop screw to set the end position safely without load-holding reliance.
To replace the discontinued SIJ100X200-100S, order the exact direct replacement SAIJ100X200-100S to reuse your existing FA, LB, or TC ISO 15552 mounts. Choose the 100mm adjust window when you need to trim the extend stroke by up to 100mm on-site; the nominal 200mm stroke remains the maximum. The -S suffix confirms the piston magnet is present for legacy CS1-B/DS1-B switches. For strokes at or above 300mm, verify side-load limits to prevent rod binding. Note that the external stop screw sets end position and is not a lock; for load holding on air loss, specify an external rod lock, pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
Yes, the SIJ100X200-100S is discontinued. The direct replacement is the SAIJ100X200-100S. It shares the same ISO 15552 mounting interface, 100mm bore, 200mm nominal stroke, G1/2 port, and force ratings, but features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw offers a 100mm adjust window, allowing you to shorten the extend stroke on-site from the 200mm maximum down to 100mm. The stop sets end position only and is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ100X200-100S replacement — usually within 7-8 hours.
