This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X250-10, 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 SIJ32X250-10
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X250-10 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 SAIJ32X250-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-10
The AirTAC SIJ32X250-10 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. Its external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 240-250 mm extend window from the 250 mm nominal maximum.
As SIJ is end-of-life, the direct replacement is the SAIJ32X250-10, retaining the same interface, force, and port. The SAIJ upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. 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 SIJ32X250-10 Is Used
Actuator End-Position Tuning
Dialing in a precise 240-250 mm extend endpoint on a clamping fixture without machining custom spacers.
Transfer Stroke Adjustment
Trimming the extend stroke by up to 10 mm on-site to accommodate slight package size variations.
Prototype Machinery Setup
Fine-tuning the extend endpoint during initial commissioning before finalizing fixed-stroke dimensions.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X250-10 with the SAIJ32X250-10
To replace the discontinued SIJ32X250-10, order the direct replacement SAIJ32X250-10, which keeps the 250 mm stroke, 10 mm adjust window, G1/8 port, and ISO 15552 mounting. To size both ways, the neighbouring 40 mm bore raises push force to 628 N at 0.5 MPa, while dropping to a smaller bore is not available below 32 mm. Choose the 10 mm adjust window if you need precise 240-250 mm extend endpoint tuning. Mounting options include FA, LB, and TC brackets. This SKU lacks the -S suffix, so it cannot take a magnetic switch. For strokes of 300 mm or longer, verify your side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X250-10
- ✓ 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 SIJ32X250-10 FAQ
Yes, the SIJ32X250-10 is discontinued. The direct replacement is the SAIJ32X250-10. It shares the same ISO 15552 interface, 32 mm bore, 250 mm stroke, 10 mm adjust window, G1/8 port, and mounting, but adds an upgraded Y-shaped piston seal.
The external stop screw provides a 10 mm adjust window, allowing you to trim the extend stroke from 250 mm down to 240 mm. The stop sets end position and is not a load lock.
