This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-30S, 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 SIJ32X175-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 175mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X175-30S, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ32X175-30S 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 30 mm on-site, giving a usable 145-175 mm range (175 mm nominal maximum). The 32 mm bore uses a G1/8 port, M10x1.25 rod thread, and 27 mm adjustable cushions. Because this model is end-of-life, the direct replacement is the SAIJ32X175-30S—identical ISO 15552 mounting interface, force, stroke, and adjust window.
The SAIJ successor retains these ratings but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The -S suffix on this unit denotes a built-in piston magnet for legacy CS1-B/DS1-B switches (the SAIJ replacement uses current AirTAC switches).

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAIJ32X175-30S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.

The SAIJ32X175-30S 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).
Light-duty pressing tasks needing field stroke tuning to accommodate material thickness variations without swapping cylinders.
Ejecting parts of differing widths on a line, using the 30 mm on-site extend trim to precisely set the push distance.
Actuating a diverting mechanism where the extend endpoint requires occasional manual readjustment to handle changing package sizes.
To replace the discontinued SIJ32X175-30S, order the direct replacement SAIJ32X175-30S; it preserves the 175 mm maximum stroke, 30 mm adjust window, G1/8 port, and ISO 15552 mounting dimensions. Choose the 30 mm adjust window if your end-position tuning falls within 145-175 mm; the stop screw sets the end position but is not a load lock. Mounting attachments (FA, LB, TC) reuse the ISO 15552 interface. The -S magnet supports position sensing. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
Yes, the SIJ32X175-30S is discontinued. The direct replacement is the SAIJ32X175-30S. It shares the same ISO 15552 interface, 32 mm bore, 175 mm stroke, 30 mm adjust window, and G1/8 port, but features an upgraded piston seal.
The external stop screw provides a 30 mm adjust window, allowing you to shorten the extend stroke from 175 mm down to 145 mm. The stop sets end position and does not hold loads; use an external rod lock or SAIL/BSAI variant for load holding.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ32X175-30S replacement — usually within 7-8 hours.
