This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X200-20S, 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 SIJ100X200-20S 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 SAIJ100X200-20S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ100X200-20S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 180-200 mm stroke from the 200 mm nominal maximum. It includes a -S piston magnet for legacy CS1-B/DS1-B switches.
This unit is replaced direct by the SAIJ100X200-20S, retaining the ISO 15552 mounting interface, bore, force, and adjust window. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The stop screw sets end position only; it is not a load lock.

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).
Allows precise 0-20 mm on-site extend stroke reduction to set exact press-fit depth without machining custom spacers.
Adjusts the extend stop on-site to tune the diverter stroke window for varying product widths on the line.
Trims the extend stroke by up to 20 mm to dial in exact pusher end positions for pallet handling changes.
To replace the discontinued SIJ100X200-20S, order the direct replacement SAIJ100X200-20S, keeping the 20 mm adjust window (180-200 mm usable extend) and -S magnet. Reuse FA, LB, or TC mounts via the ISO 15552 interface. For strokes >=300 mm, verify side-load limits. The stop screw sets end position but does not hold loads on air loss; for load holding use SAIL/BSAI or an external rod lock.
Replacement checklist
Yes, the SIJ100X200-20S is discontinued. The direct replacement is the SAIJ100X200-20S. It shares the same ISO 15552 interface, 100 mm bore, 200 mm stroke, 20 mm adjust window, G1/2 port, and mounting, but uses an upgraded piston seal.
The external stop screw window is 20 mm, allowing you to trim the extend stroke from 200 mm down to 180 mm on-site. The stop sets end position and is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ100X200-20S replacement — usually within 7-8 hours.
