This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X30-30S, 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 SIJ32X30-30S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X30-30S 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 SAIJ32X30-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X30-30S
The AirTAC SIJ32X30-30S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 30mm on-site, giving a usable 0-30mm extend window from the 30mm nominal maximum. The direct replacement is the SAIJ32X30-30S, matching the interface, force, and mounting.
The SAIJ upgrade utilizes an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long 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 SIJ32X30-30S Is Used
Short-Stroke Clamping
Dialing in the exact clamping contact point on delicate workpieces where a fixed 30mm stroke would apply too much energy.
Transfer Diverter
Fine-tuning the diverter gate extension length on-site to accommodate different package widths without changing the cylinder.
Light Press Fit
Adjusting the extend stop to set precise insertion depths for small bearings or pins during light assembly operations.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X30-30S with the SAIJ32X30-30S
To replace the discontinued SIJ32X30-30S, order the direct replacement SAIJ32X30-30S, which preserves the 32mm bore, 30mm nominal stroke, 30mm adjust window, and G1/8 port. Choose the 30mm adjust window when you need to dial in the extend end-position on-site. Mounting options include Basic, FA, LB, and TC brackets. The -S suffix ensures a piston magnet is present for legacy CS1-B/DS1-B sensors. For strokes at or above 300mm, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X30-30S
- ✓ 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 SIJ32X30-30S FAQ
Yes, the SIJ32X30-30S is discontinued. The direct replacement is the SAIJ32X30-30S. It shares the same ISO 15552 interface, 32mm bore, 30mm nominal stroke, 30mm adjust window, and G1/8 port, but uses an upgraded piston seal for longer life.
The external stop screw allows you to trim the extend stroke by up to 30mm on-site, yielding a usable 0-30mm extend window. The stop sets end position and is not a load lock.
