This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X300-20, 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 SIJ32X300-20
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X300-20 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 300mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X300-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-20
The AirTAC SIJ32X300-20 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 300 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 280-300 mm extension. This SKU lacks a magnet (-S omitted), so it cannot accept a magnetic switch for position sensing. The stop screw strictly sets the end position; it is not a load lock, and the cylinder will drift on air loss.
The direct replacement is the SAIJ32X300-20, matching the G1/8 port, M10x1.25 rod thread, and 27 mm adjustable cushions. The SAIJ upgrade features an improved two Y-shaped one-way piston seal for lower start-up pressure and longer life.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-20 Is Used
Light Assembly Pinning
Tuning the extend stroke by up to 20 mm on-site to seat small pins precisely without re-engineering the entire fixture.
Package Divert Stroke Trim
Adjusting the extend end-position to accommodate varying package widths on a 32 mm bore diverting mechanism.
Fixture Clamping Calibration
Dialing in the exact 280-300 mm extension needed to clamp delicate workpieces without over-travel damage.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X300-20 with the SAIJ32X300-20
To replace the discontinued SIJ32X300-20, order the direct replacement SAIJ32X300-20, which preserves the 32 mm bore, 300 mm nominal stroke, 20 mm adjust window, and ISO 15552 mounting interface. Choose the 20 mm adjust window if your end-stop requires field tuning between 280 mm and 300 mm. Mounting attachments (FA, LB, TC) are fully reusable. Because the 300 mm stroke exceeds 300 mm, ensure external guides are used to mitigate side-load and rod-bending risks. This non-magnetic SKU cannot support legacy CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X300-20
- ✓ 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 SIJ32X300-20 FAQ
Yes, the SIJ32X300-20 is discontinued. The direct replacement is the SAIJ32X300-20. It shares the same ISO 15552 interface, 32 mm bore, 300 mm stroke, 20 mm adjust window, G1/8 port, and mounting options. The SAIJ also uses an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw allows you to trim the extend stroke by up to 20 mm on-site, giving a usable extension of 280-300 mm. The stop sets end position only; it is not a load lock.
