This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X30-20S, 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 SIJ32X30-20S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X30-20S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 30mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X30-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X30-20S
The AirTAC SIJ32X30-20S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32mm bore and 30mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 10-30mm end position. This SIJ model is discontinued; the direct replacement is the SAIJ32X30-20S, retaining 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. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X30-20S Is Used
Short-Stroke Clamping
Ideal for clamping small parts where the exact contact point varies, using the 20mm adjust window to tune the 10-30mm extend stroke on-site.
Component Seating
Useful for pressing or seating lightweight components, allowing operators to dial in the precise end position without re-engineering the fixture.
Actuator Prototyping
Valuable in R&D setups where the effective extend stroke must be iteratively shortened during testing to find the optimal kinematic stop.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X30-20S with the SAIJ32X30-20S
To replace the discontinued SIJ32X30-20S, specify SAIJ32X30-20S for an direct match. Choose the 20mm adjust window if your application requires field tuning of the extend stroke within a 10-30mm range. Mounting options include FA, LB, and TC brackets. The -S magnet supports legacy CS1-B/DS1-B sensors. Because the 30mm stroke is under 300mm, side-load concerns are minimal, but note that a plain cylinder does not hold loads without live air.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X30-20S
- ✓ 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 SIJ32X30-20S FAQ
Yes, the SIJ32X30-20S is discontinued. The direct replacement is the SAIJ32X30-20S, which shares the same ISO 15552 interface, 32mm bore, 30mm stroke, 20mm adjust window, and G1/8 port. The SAIJ features an upgraded piston seal for longer life.
The external stop screw provides a 20mm adjust window, allowing you to shorten the 30mm nominal extend stroke down to 10mm. The stop sets end position and is not a load lock.
