This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X30-20, 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 SIJ32X30-20 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 30mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X30-20, which matches its ISO interface, bore, stroke, force and mounting.
The AirTAC SIJ32X30-20 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 20mm on-site, yielding a usable 10-30mm extend out of the 30mm nominal maximum. The stop sets the end position but is not a load lock; loads drift on air loss.
The direct replacement is the SAIJ32X30-20, sharing the same interface, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. This non-magnet SKU cannot take a switch.

The SAIJ32X30-20 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).
Provides field-tunable 10-30mm clamping travel for delicate workpieces, allowing operators to dial in the exact grip without swapping cylinders.
Adjusts the extend stop on-site to eject parts of varying heights from a fixture, using the 20mm trim window to accommodate product changes.
Sets a precise mechanical end-position for a 10-30mm probing motion where repeatability is handled mechanically rather than via soft stops.
To replace the discontinued SIJ32X30-20, order the direct replacement SAIJ32X30-20, which preserves the 20mm adjust window, G1/8 port, and 30mm nominal stroke. Choose the 20mm adjust window if you need field tuning between 10mm and 30mm; for fixed stops, a standard SAI is simpler. Mounting reuses ISO 15552 FA, LB, or TC interfaces. As this SKU lacks the -S magnet, it cannot accept a sensor; for legacy sensing use CS1-B/DS1-B on magnet-equipped models. Because the 30mm stroke is under 300mm, side-load rod deflection is minimal. For load holding, use SAIL/BSAI or an external rod lock, as the adjust screw is not a brake.
Replacement checklist
Yes, the SIJ32X30-20 is discontinued. The direct replacement is the SAIJ32X30-20. It shares the same ISO 15552 interface, 32mm bore, 30mm nominal stroke, 20mm adjust window, G1/8 port, and mounting, but adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw window is 20mm, allowing you to shorten the 30mm nominal extend stroke down to 10mm on-site. The stop sets end position and is not a load lock; for held loads use SAIL/BSAI or an external rod lock.
Send us the quantity and destination. We confirm price, stock and lead time on the SAIJ32X30-20 replacement — usually within 7-8 hours.
