This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X400-30S, 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 SIJ32X400-30S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X400-30S 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 SAIJ32X400-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-30S
The AirTAC SIJ32X400-30S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ32X400-30S. Its external stop screw lets you trim the extend stroke by up to 30mm on-site, giving a usable 370-400mm stroke out of the 400mm nominal maximum.
The SAIJ direct keeps the exact ISO 15552 mounting interface, force, and adjust window, while upgrading to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches. Note that the stop screw sets end position but is not a load lock; cylinders drift on air loss, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-30S Is Used
Variable Pitch Pushing
Tuning the extend stroke on-site by up to 30mm allows precise positioning of parts into machining fixtures without machining custom spacers.
Adjustable Transfer Stops
Field-adjusting the 370-400mm extend stop accommodates different package sizes on a conveyor line without changing out the entire actuator.
Variable Depth Diverter
Trimming the extend stroke in the field lets a sorting diverter handle varying product depths accurately before hitting the end of stroke.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X400-30S with the SAIJ32X400-30S
To replace the discontinued SIJ32X400-30S, order the exact direct replacement SAIJ32X400-30S, which preserves the 32mm bore, 400mm stroke, 30mm adjust window, G1/8 port, and ISO 15552 mounting. Choose the 30mm adjust window if you need on-site extend tuning between 370-400mm. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix ensures a piston magnet for legacy CS1-B/DS1-B switches. Because the 400mm stroke is long, always use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X400-30S
- ✓ 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 SIJ32X400-30S FAQ
Yes, the SIJ32X400-30S is discontinued. The direct replacement is the SAIJ32X400-30S. It shares the same ISO 15552 interface, 32mm bore, 400mm stroke, 30mm adjust window, G1/8 port, and mounting, but upgrades to a two Y-shaped one-way piston seal for longer life.
The external stop screw allows you to trim the extend stroke by up to 30mm on-site, yielding a usable extend range of 370-400mm. The stop sets end position and is not a load lock.
