This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-30, 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 SIJ32X175-30
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X175-30 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 SAIJ32X175-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-30
The AirTAC SIJ32X175-30 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore and 175 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 145-175 mm window.
The SAIJ direct retains the exact ISO 15552 mounting interface, force, and cushion, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note this non-magnetic SKU cannot take a switch, and the stop screw sets end position only—it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-30 Is Used
Adjustable Stop Pressing
Light-duty assembly presses needing field-tuned extend stops within a 145-175 mm window to accommodate varying material thicknesses without re-plumbing.
Variable Length Diverting
Package diverters on conveyors where the 30 mm external stop screw adjusts the actuator's reach on-site to handle changing box dimensions.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-30 with the SAIJ32X175-30
To replace the SIJ32X175-30, order the SAIJ32X175-30; it keeps the 175 mm stroke, 30 mm adjust window, G1/8 port, and M10x1.25 rod thread. Choose the 30 mm adjust window if you need precise field tuning of the extend position. Mounting options include Basic, FA, LB, and TC brackets. Because this is a non-S SKU, it cannot accept a magnetic switch; add external sensing if needed. For strokes of 300 mm or longer, verify your side-load limits to prevent rod distortion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-30
- ✓ 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 SIJ32X175-30 FAQ
Yes, the SIJ32X175-30 is discontinued. The direct replacement is the SAIJ32X175-30, which matches the ISO 15552 interface, 32 mm bore, 175 mm stroke, 30 mm adjust window, G1/8 port, and mounting dimensions, while adding an upgraded piston seal.
The external stop screw allows you to trim the extend stroke by up to 30 mm on-site, giving a usable range of 145-175 mm. The stop sets end position and is not a load lock.
