This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-20S, 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 SIJ32X175-20S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X175-20S 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 SAIJ32X175-20S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-20S
The AirTAC SIJ32X175-20S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and replaced by the SAIJ32X175-20S. The external stop screw lets you trim the extend stroke by up to 20mm on-site, giving a usable 155-175mm window.
The SAIJ direct keeps the same ISO 15552 mounting interface, force, and adjust window, but upgrades to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-20S Is Used
Adjustable End-Stop Pressing
Dialing in the exact 155-175mm extend contact point on-site for light pressing tasks without machining custom spacers.
Variable Length Diverting
Tuning the extend stroke on a diverting gate to accommodate varying package sizes on a packaging line.
Field-Calibrated Ejector
Setting the precise ejection distance for parts of varying widths, allowing quick changes via the external stop screw.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-20S with the SAIJ32X175-20S
To replace the discontinued SIJ32X175-20S, order the direct replacement SAIJ32X175-20S, which retains the 175mm nominal stroke, 20mm adjust window, G1/8 port, and M10x1.25 rod thread. Choose the 20mm adjust window if your application requires field tuning the extend stroke between 155mm and 175mm. Reuse existing FA, LB, or TC ISO 15552 mounts. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). For strokes of 175mm, verify side-load guide geometry to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-20S
- ✓ 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 SIJ32X175-20S FAQ
Yes, the SIJ32X175-20S is discontinued. The direct replacement is the SAIJ32X175-20S, sharing the same ISO 15552 interface, 32mm bore, 175mm stroke, 20mm adjust window, G1/8 port, and mounting options.
The external stop screw provides a 20mm adjust window, allowing the extend stroke to be shortened from the 175mm maximum down to 155mm on-site.
