This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-40, 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 SIJ32X175-40
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X175-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 175mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X175-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-40
The AirTAC SIJ32X175-40 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ32X175-40. The external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 135-175 mm stroke.
The SAIJ direct retains the ISO 15552 mounting interface, bore, and force, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-40 Is Used
Divergent Part Ejection
Tuning the extend stroke on-site by up to 40 mm allows a single cylinder to push varying part lengths without swapping the entire actuator.
Adjustable Transfer Stops
The 135-175 mm usable stroke window accommodates changing package sizes on a line, letting operators dial in the stop position precisely.
Prototype Tooling Setup
During fixture development, the external stop screw provides rapid end-position adjustments to test engagement depths before finalizing the design.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-40 with the SAIJ32X175-40
To replace the discontinued SIJ32X175-40, order the exact direct replacement SAIJ32X175-40. Choose the 40 mm adjust window if your extend stroke needs on-site tuning between 135 and 175 mm. Mounting options include FA, LB, and TC. This SKU lacks the -S magnet and cannot take a sensor. For stroke lengths over 300 mm, verify side-load limits to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
