This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X275-100, 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 SIJ32 Double Rod Adjustable Cylinder SIJ32X275-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 275mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X275-100, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ32X275-100 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 175-275 mm extend out of the 275 mm nominal maximum. The stop sets the end position but is not a load lock.
The direct replacement is the SAIJ32X275-100, retaining the same interface, force, and port. The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this SKU lacks a -S magnet and cannot take a sensor.

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 operators to fine-tune the extend stroke on-site by up to 100 mm to accommodate different material thicknesses without changing the entire cylinder setup.
Provides a 175-275 mm extend range to reposition sorting gates precisely along the line as product sizes change, using the external stop screw for rapid field adjustments.
Delivers precise carton flap tucking by trimming the extend stroke on-site to match varying package depths, ensuring consistent mechanical end-positioning.
To replace the discontinued SIJ32X275-100, specify the direct replacement SAIJ32X275-100, keeping the 32 mm bore, 275 mm stroke, 100 mm adjust window, and G1/8 port. Choose the 100 mm adjust window if your application requires trimming the extend stroke on-site across a wide 175-275 mm range. Reuse existing FA, LB, or TC ISO 15552 mounting hardware. Because this SKU has no -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; add external sensing if needed. For stroke lengths >=300 mm, verify side-load tolerance to prevent rod binding. Remember the adjust stop sets end position and is not a lock; for load holding on air loss, use an external rod lock or the SAIL/BSAI variants.
Replacement checklist
Yes, the AirTAC SIJ32X275-100 is discontinued. The direct replacement is the SAIJ32X275-100. It offers the same ISO 15552 interface, 32 mm bore, 275 mm nominal stroke, 100 mm adjust window, G1/8 port, and force ratings, but features an upgraded two Y-shaped one-way piston seal for longer life and lower start-up pressure.
The external stop screw window is 100 mm, allowing you to trim the extend stroke on-site from the 275 mm maximum down to 175 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 SAIJ32X275-100 replacement — usually within 7-8 hours.
