This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X450-100, 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 SIJ32X450-100
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X450-100 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 SAIJ32X450-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-100
The AirTAC SIJ32X450-100 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 100 mm on-site, giving a usable range of 350-450 mm from the 450 mm nominal maximum. This 32 mm bore uses a G1/8 port, M10x1.25 rod thread, and 27 mm adjustable cushions. The direct replacement is the SAIJ32X450-100, matching the interface, force, and mounting.
The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure. The stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-100 Is Used
Variable Push Assembly
Tuning the extend stroke on-site by up to 100 mm to accommodate different part heights without swapping the entire cylinder.
Adjustable Diverter Arm
Setting a precise end position for a routing flap that handles varying package widths on a packaging line.
Variable Depth Stop
Acting as an end stop where the required material feed length changes occasionally, trimmed via the external screw.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X450-100 with the SAIJ32X450-100
To replace the discontinued SIJ32X450-100, order the exact direct replacement SAIJ32X450-100, keeping the 100 mm adjust window (350-450 mm usable extend) and G1/8 port. For sizing both ways: the 40 mm neighbour bore raises 0.5 MPa push to 628 N, while a smaller fixed stroke may suit limited spaces. Mounting reuses ISO 15552 interface dimensions (Basic, FA, LB, TC). This SKU lacks the -S magnet, so it cannot take a magnetic switch; add -S if you need legacy CS1-B/DS1-B sensor accuracy. At 450 mm stroke, mind side-load and rod-bending—use external guides to prevent binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X450-100
- ✓ 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 SIJ32X450-100 FAQ
Yes, the SIJ32X450-100 is discontinued. The direct replacement is the SAIJ32X450-100, offering the same ISO 15552 interface, 450 mm stroke, 100 mm adjust window, and G1/8 port.
The external stop screw window is 100 mm, allowing a usable extend stroke of 350-450 mm. The stop sets end position and is not a load lock.
