This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X75-75, 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 SIJ32 Double Rod Adjustable Cylinder SIJ32X75-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 75mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X75-75, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ32X75-75 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 75mm on-site, dropping the 75mm nominal stroke down to a 0mm minimum. The stop sets the end position but is not a load lock.
The direct replacement is the SAIJ32X75-75, matching the interface, force, and 27mm adjustable cushions. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. This non-magnet SKU cannot take a switch.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ32X75-75 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAIJ32X75-75 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

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 for pressing parts to different depths without swapping the entire cylinder body.
Tunes the pusher extension length to accommodate changing package widths on a packaging line.
Allows engineers to dial in the exact extend end position during fixture testing before finalizing hard stops.
Replace the SIJ32X75-75 directly with the SAIJ32X75-75, retaining your FA, LB, or TC ISO 15552 mounts. Choose the 75mm adjust window when full extend length varies per job. Because this SKU lacks a -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For stroke lengths over 300mm, verify side-load guide tolerance. The stop screw sets end position only; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.
Replacement checklist
Yes, the SIJ32X75-75 is discontinued.
The external stop screw window is 75mm, letting you shorten the 75mm nominal extend stroke down to 0mm 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 SAIJ32X75-75 replacement — usually within 7-8 hours.
