This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X35-30, 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 SIJ32X35-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X35-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 35mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X35-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X35-30
The AirTAC SIJ32X35-30 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32mm bore and G1/8 port. Its external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 5-35mm stroke. The nominal 35mm stroke is the maximum. The direct replacement is the SAIJ32X35-30, sharing the same interface, force, and mounting.
The SAIJ upgrade features an improved two Y-shaped one-way piston seal for lower start-up pressure and longer life. This non-magnet SKU cannot take a switch. The stop sets end position but is not a load lock; use an external rod lock or SAIL/BSAI for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X35-30 Is Used
Short-Stroke Clamping
Ideal for clamping delicate components where the extend stop screw must be dialed in precisely on-site to avoid crushing, utilizing the 5-35mm usable stroke window.
Sensor-Free Ejector
Suitable for simple pneumatic ejection of small parts where position sensing is handled externally, as this non-magnet SKU cannot carry a reed switch.
Adjustable Spacer Insertion
Perfect for inserting spacers or pins at varying depths on a single fixture, using the 30mm on-site stroke trim to adapt the extend end position without changing cylinders.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X35-30 with the SAIJ32X35-30
To replace the discontinued SIJ32X35-30, use the SAIJ32X35-30 direct directly—matching the 32mm bore, 35mm nominal stroke, 30mm adjust window, and G1/8 port. The 30mm adjust window is ideal for fine-tuning the extend end position without machining. Mounting options include Basic, FA, LB, and TC. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch. The 35mm stroke is under 300mm, so side-load rod deflection is minimal.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X35-30
- ✓ 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 SIJ32X35-30 FAQ
Yes, the SIJ32X35-30 is discontinued. The direct replacement is the SAIJ32X35-30, which shares the same ISO 15552 interface, 32mm bore, 35mm stroke, 30mm adjust window, and G1/8 port. The SAIJ family also uses an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw allows trimming the extend stroke by up to 30mm on-site, giving a usable 5-35mm stroke. The stop sets end position only; it is not a load lock.
