This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X175-100S, 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 SIJ32X175-100S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X175-100S 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 SAIJ32X175-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-100S
The AirTAC SIJ32X175-100S 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 100 mm on-site, giving a usable 75-175 mm window from the 175 mm nominal maximum. The direct replacement is the SAIJ32X175-100S, sharing the same interface, force, and mounting.
The SAIJ successor upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches; the SAIJ uses current switches. Remember the stop screw sets end position only—it is not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-100S Is Used
Variable Depth Drilling Jig
Trimming the 175 mm extend stroke by up to 100 mm on-site allows a single cylinder to drive a drill head to multiple precise depths without swapping mechanical hardstops.
Adjustable Diverter Arm
An external stop screw sets the exact reach of a sorting pusher across varying package widths, providing a 75 to 175 mm usable stroke window on the line.
Variable Position Stops
Calibrating end positions in a compact 32 mm bore assembly is simplified by field-tuning the extend stroke, adapting the stop distance to changing pallet sizes.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-100S with the SAIJ32X175-100S
To replace the discontinued SIJ32X175-100S, order the exact direct replacement SAIJ32X175-100S to reuse your ISO 15552 mounting and G1/8 porting. Choose the 100 mm adjust window if your application requires field tuning the extend stroke between 75 and 175 mm. Select FA, LB, or TC mountings to match your fixture. The -S magnet supports legacy CS1-B/DS1-B sensors (SAIJ uses current switches). For strokes at or above 300 mm, verify side-load guiding. Because the stop screw is not a lock, specify an external rod lock or SAIL/BSAI variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-100S
- ✓ 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 SIJ32X175-100S FAQ
Yes, the SIJ32X175-100S is discontinued. The direct replacement is the SAIJ32X175-100S, which shares the same ISO 15552 interface, 32 mm bore, 175 mm nominal stroke, 100 mm adjust window, G1/8 port, and mounting options. The SAIJ family also features an upgraded piston seal and adds lock variants like SAIL and BSAI.
The external stop screw provides a 100 mm adjust window, allowing you to shorten the extend stroke from the 175 mm maximum down to 75 mm on-site. The stop sets end position only and does not lock the load.
