This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X160-75, 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 SIJ100X160-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X160-75, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ100X160-75 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 75 mm on-site, yielding a usable 85-160 mm range from the 160 mm nominal maximum. The 100 mm bore uses a G1/2 port, a 25 mm rod with an M20x1.5 thread, and 36 mm adjustable air cushions.
The direct replacement is the SAIJ100X160-75, preserving the interface, force, and port. The SAIJ upgrade uses a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note: the stop sets end position but is not a load lock; drift occurs on air loss.

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).
Adjusts the extend stroke on-site to set precise pressing depths for bearings without swapping the entire cylinder body.
Trims the extend position to deflect varying package sizes on a conveyor line, ensuring accurate routing without repositioning mounts.
Sets a custom mechanical end position for pallet lifting or positioning tasks where the exact stopping point must be dialed in per batch.
To replace this discontinued unit, order the SAIJ100X160-75, which matches the 160 mm stroke, 75 mm adjust window, G1/2 port, and ISO 15552 mounting. Choose the 75 mm adjust window if you need to tune the extend stroke down to 85 mm on-site. Reuse FA, LB, or TC mounts. This SKU lacks the -S magnet, so it cannot take a magnetic switch; add -S for legacy CS1-B/DS1-B sensor accuracy. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
Yes, the SIJ100X160-75 is discontinued. The direct replacement is the SAIJ100X160-75. It shares the identical ISO 15552 interface, 100 mm bore, 160 mm stroke, 75 mm adjust window, G1/2 port, and mounting options. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw provides a 75 mm adjust window, shortening the 160 mm nominal extend stroke down to 85 mm. The stop sets end position and is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ100X160-75 replacement — usually within 7-8 hours.
