This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X140-30S, 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 SIJ32X140-30S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X140-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 140mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X140-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X140-30S
The AirTAC SIJ32X140-30S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore, 140 mm nominal stroke, and a built-in piston magnet. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable extend range of 110-140 mm. The SIJ32X140-30S is discontinued; the direct replacement is the SAIJ32X140-30S, which shares the same interface, force, and adjust window.
Upgrading to the SAIJ family retains the ISO 15552 mounting dimensions but introduces an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. The external stop screw sets the end position but is not a load lock; for held loads, use an external rod lock or the SAIL/BSAI variants.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X140-30S Is Used
Adjustable End-Stop Pressing
Trimming the extend stroke by up to 30 mm on-site allows precise, repeatable pressing forces without machining custom spacers.
Variable Length Diverter
Field-tuning the extend stroke from 110 to 140 mm accommodates changing package sizes on a conveyor line.
Adaptable Push-Off Mechanism
The external stop screw provides quick extend adjustments to push varying pallet widths from a staging area.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X140-30S with the SAIJ32X140-30S
To replace the discontinued SIJ32X140-30S, order the direct replacement SAIJ32X140-30S, keeping the 32 mm bore, 140 mm stroke, 30 mm adjust window, and -S magnet for legacy CS1-B/DS1-B switches. Choose the 30 mm adjust window if your extend stroke needs field tuning between 110 mm and 140 mm. Mounting options include Basic, FA, LB, and TC using the ISO 15552 interface. For strokes of 300 mm or longer, verify side-load limits to prevent excessive rod wear. Remember the stop screw sets position but does not lock; pilot-operated check valves or SAIL/BSAI lock variants are required for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X140-30S
- ✓ 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 SIJ32X140-30S FAQ
Yes, the SIJ32X140-30S is discontinued. The direct replacement is the SAIJ32X140-30S, which matches the 32 mm bore, 140 mm stroke, 30 mm adjust window, G1/8 port, and ISO 15552 mounting interface.
The external stop screw offers a 30 mm adjust window, allowing the extend stroke to be shortened from the 140 mm maximum down to 110 mm. The stop sets end position and is not a load lock.
