This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X125-75, 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 SIJ32X125-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 125mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X125-75, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ32X125-75 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, giving a usable 50-125 mm window from the 125 mm maximum. The direct replacement is the SAIJ32X125-75, matching the interface, force, and mounting.
The stop screw sets the end position but is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or SAIL/BSAI variant for held loads. This non-magnet SKU cannot take a switch. Upgrading to SAIJ brings an upgraded two-piece Y-shaped piston seal for lower start-up pressure.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ32X125-75 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAIJ32X125-75 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).
Adjust the extend stroke on-site to match different material thicknesses, setting a precise 50-125 mm drilling depth without swapping cylinders.
Tune the pusher extension on a packaging line to divert boxes of varying widths, using the 75 mm trim window to adapt to product changes.
Set a physical end-stop for incoming pallets at different distances, trimming the extend stroke to accommodate varying pallet sizes.
To replace the discontinued SIJ32X125-75, order the direct replacement SAIJ32X125-75, reusing your FA, LB, or TC ISO 15552 mounts and G1/8 port. The 75 mm adjust window is ideal if your extend target varies between 50 and 125 mm. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; add external physical stops if detection is required. For strokes of 300 mm or longer, carefully manage side loading to prevent rod bearing wear.
Replacement checklist
Yes, the SIJ32X125-75 is discontinued. The direct replacement is the SAIJ32X125-75, which shares the identical ISO 15552 interface, 125 mm stroke, 75 mm adjust window, G1/8 port, and mounting options.
The external stop screw provides a 75 mm adjust window, allowing the extend stroke to be shortened from the 125 mm maximum down to 50 mm on-site.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ32X125-75 replacement — usually within 7-8 hours.
