This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X450-30S, 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.
Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-30S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X450-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 450mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X450-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-30S
The AirTAC SIJ32X450-30S 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 30 mm on-site, yielding a usable 420-450 mm window from the 450 mm nominal maximum.
The direct replacement is the SAIJ32X450-30S, matching the bore, stroke, force, and mounting. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Note the stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-30S Is Used
Adjustable End-Stop Pressing
Dialing in the exact 420-450 mm extend position on-site for light pressing tasks without swapping the cylinder.
Variable Length Diverting
Tuning the diverting stroke length on a conveyor line to accommodate different package sizes on the fly.
Custom Depth Positioning
Setting precise pusher depth limits in warehousing fixtures where the exact extend point varies per run.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-30S with the SAIJ32X450-30S
To replace the discontinued SIJ32X450-30S, order the direct replacement SAIJ32X450-30S, reusing your existing ISO 15552 FA, LB, or TC mounts. The -30 adjust window lets you tune the extend end-position by up to 30 mm on-site; if you need less tuning, a smaller window reduces screw overhang. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches. Because the 450 mm stroke exceeds 300 mm, use external guides to prevent rod bending and manage side loads. The stop screw is for end-position setting, not load holding; for held loads use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X450-30S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-30S FAQ
Yes, the SIJ32X450-30S is discontinued. The direct replacement is the SAIJ32X450-30S, which shares the same ISO 15552 interface, 32 mm bore, 450 mm stroke, 30 mm adjust window, G1/8 port, and mounting options.
The external stop screw offers a 30 mm adjust window, allowing you to shorten the extend stroke from the 450 mm maximum down to 420 mm. The stop sets end position and is not a load lock.
