This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X160-100, 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X160-100, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ80X160-100 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 100 mm on-site, giving a usable 60-160 mm extend range from the 160 mm nominal maximum. It features a Ø25 mm rod, M20x1.5 rod thread, and a fixed G3/8 port.
Because the SIJ line is end-of-life, the direct replacement is the SAIJ80X160-100, retaining the same interface, bore, force, and mounting. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet and cannot take a sensor; the stop screw sets end position but 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).
Trimming the extend stroke by up to 100 mm on-site allows operators to adapt pressing depth for varying material thicknesses without swapping the entire actuator.
Tuning the extend stroke from 160 mm down to 60 mm accommodates changing package sizes on a packaging line, ensuring precise physical diverting contact.
To replace the discontinued SIJ80X160-100, order the SAIJ80X160-100 directly—it is a direct swap sharing the ISO 15552 dimensions, G3/8 port, and 100 mm adjust window. Choose the 100 mm adjust window if your extend stroke needs on-site tuning between 60 and 160 mm. Mounting options include FA, LB, and TC brackets. Because this SKU has no -S magnet, it cannot accept a magnetic switch; add external sensing if needed. For strokes of 300 mm or longer, carefully manage side loads to prevent excessive guide wear. The external stop sets the end position but does not lock the load—use an external rod lock or check valve for hold.
Replacement checklist
Yes, the SIJ80X160-100 is discontinued. The direct replacement is the SAIJ80X160-100, which shares the identical ISO 15552 interface, 80 mm bore, 160 mm stroke, 100 mm adjust window, G3/8 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 100 mm adjust window, allowing the extend stroke to be shortened from the 160 mm nominal maximum down to 60 mm. The stop sets end position but is not a load lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ80X160-100 replacement — usually within 7-8 hours.
