This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X350-30, 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 SIJ32X350-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X350-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 350mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X350-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-30
The AirTAC SIJ32X350-30 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore, 350 mm nominal stroke, and G1/8 port. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 320-350 mm extension window. The stop sets the end position and is not a load lock; the piston drifts on air loss. This SIJ model is discontinued; the direct replacement is the SAIJ32X350-30, retaining the same interface, force, and mounting.
The SAIJ successor uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure. This non-magnetic SKU cannot take a switch. For 350 mm strokes, use external guides to prevent rod bending.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-30 Is Used
Custom End-Position Clamping
Trimming the 350 mm extend stroke by up to 30 mm on-site allows precise clamping of varying part widths without machining custom spacers.
Adjustable Transfer Stops
Field-tuning the extend stroke from 320 to 350 mm lets operators reposition conveyor divert stops quickly for mixed product sizes.
Variable Depth Insertion
Setting the external stop screw provides exact insertion depths for packaging materials that vary by batch, ensuring consistent placement.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X350-30 with the SAIJ32X350-30
To replace the discontinued SIJ32X350-30, order the direct replacement SAIJ32X350-30, keeping the 32 mm bore, 350 mm stroke, 30 mm adjust window, and G1/8 port. Choose the 30 mm adjust window when you need precise 320-350 mm end-position tuning without external stops. Mounting uses ISO 15552 FA, LB, or TC interfaces. This SKU has no -S magnet and cannot support legacy CS1-B/DS1-B sensors. Because the 350 mm stroke exceeds 300 mm, account for side-load and rod-bending by adding external guides. The cylinder does not hold loads without live air; use SAIL, BSAI, or an external rod lock for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X350-30
- ✓ 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 SIJ32X350-30 FAQ
Yes, the SIJ32X350-30 is discontinued. The direct replacement is the SAIJ32X350-30, which shares the same ISO 15552 interface, 32 mm bore, 350 mm stroke, 30 mm adjust window, and G1/8 port.
The external stop screw offers a 30 mm adjust window, shortening the 350 mm nominal extend stroke to a minimum of 320 mm. The stop sets end position and is not a load lock.
