This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X250-30S, 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 SIJ32X250-30S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 250mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X250-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30S
The AirTAC SIJ32X250-30S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 250 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 220-250 mm forward travel. The stop sets the end position but is not a load lock. It features a G1/8 port, M10x1.25 rod thread, and 27 mm adjustable air cushions. The direct replacement is the SAIJ32X250-30S, matching the bore, force, adjust window, and mounting interface.
The SAIJ successor retains these ratings while using an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30S Is Used
Variable Depth Drilling Jig
Trimming the extend stroke by up to 30 mm on-site allows a drill head to accommodate multiple material thicknesses without re-fabricating the entire fixture.
Adjustable Transfer Pusher
Tuning the 220-250 mm forward travel lets operators change the pusher end position for varying box sizes directly at the conveyor line.
Multi-Format Sealing Press
The external stop screw sets the precise lower end position for different package heights, ensuring consistent sealing pressure without complex reprogramming.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-30S with the SAIJ32X250-30S
To replace the discontinued SIJ32X250-30S, order the direct replacement SAIJ32X250-30S, which preserves the ISO 15552 mounting interface, G1/8 port, and 30 mm adjust window. Choose the 30 mm adjust window if your application requires field tuning of the extend stroke within 220-250 mm. Mounting options include FA, LB, and TC brackets. The -S suffix ensures piston magnet compatibility for legacy CS1-B/DS1-B switches. For strokes of 300 mm or longer, verify side-load limits to prevent excessive guide wear. A plain cylinder does not hold loads on air loss; use an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X250-30S
- ✓ 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 SIJ32X250-30S FAQ
Yes, the AirTAC SIJ32X250-30S is discontinued. The direct replacement is the SAIJ32X250-30S. It shares the same ISO 15552 interface, 32 mm bore, 250 mm stroke, 30 mm adjust window, G1/8 port, and mounting options, while adding an upgraded piston seal for longer life.
The external stop screw provides a 30 mm adjust window, allowing you to shorten the extend stroke from the 250 mm maximum down to 220 mm. The stop sets end position and is not a load lock.
