This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ125X160-10, 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 SIJ125 Double Rod Adjustable Cylinder SIJ125X160-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø125mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ125X160-10, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ125X160-10 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder featuring a 125 mm bore and 160 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 150-160 mm extension. This SIJ model is discontinued; the direct replacement is the SAIJ125X160-10, matching the interface, force, and mounting.
The SAIJ upgrade incorporates a two Y-shaped one-way piston seal for low start-up pressure and extended life. Note this non-magnetic SKU cannot accept a switch. The stop screw sets end position only; it is not a lock, so use an external rod lock or SAIL/BSAI variant for load holding 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).
Field-trim the 10 mm extend window to dial in exact bearing seating depth without machining new hard stops.
Adjust the extend end position on-site to fine-tune product push-off distance across varying package widths.
Shorten the extend stroke by up to 10 mm to calibrate pallet halt points precisely at the staging lane.
To replace the discontinued SIJ125X160-10, order the direct replacement SAIJ125X160-10, keeping the 160 mm stroke and 10 mm adjust window. Choose the 10 mm adjust window when you need precise 150-160 mm extend tuning. Mounting interfaces include FA, LB, and TC. As this SKU lacks the -S magnet, it cannot take a sensor; add -S for legacy CS1-B/DS1-B switch compatibility. For strokes of 300 mm or longer, verify side-load limits to prevent rod bearing wear.
Replacement checklist
Yes, the SIJ125X160-10 is discontinued. The direct replacement is the SAIJ125X160-10, offering the same ISO 15552 interface, 125 mm bore, 160 mm stroke, 10 mm adjust window, and G1/2 port.
The external stop screw window is 10 mm, allowing you to trim the extend stroke from 160 mm down to 150 mm.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ125X160-10 replacement — usually within 7-8 hours.
