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

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-75S
The AirTAC SIJ32X175-75S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, giving a usable 100-175 mm extension out of the 175 mm nominal maximum. This SIJ model is discontinued; the direct replacement is the SAIJ32X175-75S, retaining the same interface, force, and adjust window.
The SAIJ successor incorporates an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches. Note that the stop screw sets the end position but is not a load lock; for held loads without live air, use an external rod lock or the SAIL/BSAI variants.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-75S Is Used
Variable Depth Drilling
Trimming the 175 mm extend stroke on-site to set precise drilling depths without swapping the entire cylinder.
Adjustable Pusher Travel
Tuning the push stroke by up to 75 mm to handle varying package sizes on a packaging line.
Prototype Actuation
Dialing in the exact extend position during machine prototype testing before finalizing fixed stops.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X175-75S with the SAIJ32X175-75S
To replace the discontinued SIJ32X175-75S, specify SAIJ32X175-75S for an direct match. Choose the 75 mm adjust window if you need to trim the 175 mm nominal extend down to a 100 mm minimum on-site. Mounting reuses ISO 15552 interface dimensions including FA, LB, and TC styles. The -S magnet supports legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, verify side-load constraints to prevent excessive guide wear. Remember, the external stop sets end position and does not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X175-75S
- ✓ 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 SIJ32X175-75S FAQ
Yes, the SIJ32X175-75S is discontinued. The direct replacement is the SAIJ32X175-75S, which shares the same ISO 15552 interface, 32 mm bore, 175 mm stroke, 75 mm adjust window, and G1/8 port.
The external stop screw allows you to shorten the extend stroke by up to 75 mm on-site, yielding a usable 100-175 mm extension. The stop sets end position and is not a load lock.
