This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X35-20, 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 SIJ32X35-20
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X35-20 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 SAIJ32X35-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X35-20
The AirTAC SIJ32X35-20 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. A 35 mm nominal extend stroke is shortened on-site by an external stop screw window of 20 mm, yielding a usable 15 to 35 mm stroke. The direct replacement is the SAIJ32X35-20, matching the G1/8 port, M10x1.25 rod thread, and 27 mm cushions.
The SAIJ upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The stop screw sets end position but is not a lock; use an external rod lock for held loads. This non-magnetic SKU cannot take a switch.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X35-20 Is Used
Short-Stroke Clamping
Adjustable end-position clamping of delicate workpieces where a fixed 35 mm stroke would over-travel and crush the part.
Diverter Gate Tuning
Field-tuning a conveyor diverter gate's extend stop by up to 20 mm to accommodate different package sizes without changing cylinders.
Prototype Actuation
Prototyping a compact pneumatic mechanism where the exact extend reach must be dialed in on-site during initial machine commissioning.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X35-20 with the SAIJ32X35-20
Replace the SIJ32X35-20 directly with the SAIJ32X35-20, reusing your ISO 15552 FA, LB, or TC mounts. Choose the 20 mm adjust window if you need field tuning of the extend end position. This SKU lacks the -S magnet and cannot support a sensor. For stroke lengths over 300 mm, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X35-20
- ✓ 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 SIJ32X35-20 FAQ
Yes, the SIJ32X35-20 is discontinued. The direct replacement is the SAIJ32X35-20. It shares the same ISO 15552 interface, 32 mm bore, 35 mm stroke, 20 mm adjust window, G1/8 port, and mounting, but adds an upgraded two Y-shaped one-way piston seal.
The external stop screw shortens the 35 mm extend stroke by up to 20 mm on-site (usable 15-35 mm). The stop sets end position and is not a load lock.
