This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X400-30, 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 SIJ32X400-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X400-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 400mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X400-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-30
The AirTAC SIJ32X400-30 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 400 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 370-400 mm extension window. The SIJ series is discontinued; the direct replacement is the SAIJ32X400-30, matching the interface, force, and mounting.
The SAIJ upgrade incorporates a two Y-shaped one-way piston seal for lower start-up pressure and longer life. This non-magnetic SKU lacks a -S sensor groove and cannot take a switch. The stop screw sets end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-30 Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site by up to 30 mm allows a single 32 mm bore cylinder to push parts of varying widths into a machining station without swapping the entire actuator.
Adjustable Diverter Arm
A 400 mm extend arm can be precisely shortened via the external stop screw to deflect different package sizes on a conveyor line, ensuring positive contact without overtravel.
End-Stop Calibration
Perfect for test fixtures where the end position must be dialed in during commissioning; the stop screw sets the exact 370-400 mm extend point without re-engineering the pneumatic layout.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-30 with the SAIJ32X400-30
To replace the discontinued SIJ32X400-30, order the direct replacement SAIJ32X400-30, retaining the 32 mm bore, 400 mm stroke, 30 mm adjust window, and G1/8 port. Choose the 30 mm adjust window if your extend stroke needs 370-400 mm of field tuning. Mounting interfaces include Basic, FA, LB, and TC. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. As the 400 mm stroke is long, account for side-load and rod-bending by using external guides to prevent premature wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X400-30
- ✓ 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 SIJ32X400-30 FAQ
Yes, the AirTAC SIJ32X400-30 is discontinued. The direct replacement is the SAIJ32X400-30. It shares the identical ISO 15552 interface, 32 mm bore, 400 mm stroke, 30 mm adjust window, and G1/8 port. The SAIJ family also upgrades the piston seal to a two Y-shaped one-way element for longer life.
The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, giving a usable extension of 370-400 mm. The stop sets end position and is not a load lock.
