This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-75, 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 SIJ32X175-75
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X175-75 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 SAIJ32X175-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-75
The AirTAC SIJ32X175-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32mm bore and 175mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 75mm on-site, yielding a usable 100-175mm extension. As the SIJ line is end-of-life, the direct replacement is the SAIJ32X175-75, retaining the same interface, force, and adjustability.
The SAIJ successor introduces an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this non-magnetic SKU cannot accept a switch. The external stop sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-75 Is Used
Divergent Tooling Positioning
Trimming the extend stroke by up to 75mm on-site allows a single cylinder to hit varied tooling heights without machining custom spacers.
Variable Length Diverter Gates
Adjustable end positioning lets operators fine-tune the extend stroke on packaging lines to accommodate different carton depths.
Prototype Fixture Calibration
During R&D, the external stop screw provides quick mechanical stroke adjustments to dial in exact clamping reach before finalizing designs.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-75 with the SAIJ32X175-75
To replace the discontinued SIJ32X175-75, order the direct replacement SAIJ32X175-75, which matches the 32mm bore, 175mm stroke, 75mm adjust window, and G1/8 port. Choose the 75mm adjust window if your application requires trimming the extend stroke down to 100mm on-site. Mounting hardware (FA, LB, TC) reuses the ISO 15552 interface. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch for sensing. For strokes of 300mm or longer, verify your side-load limits to prevent excessive guide wear. Remember the stop screw sets end position and is not a lock; without live air the piston drifts, so use an external rod lock for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-75
- ✓ 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 SIJ32X175-75 FAQ
