This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X170-30S, 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 SIJ32X170-30S
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X170-30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 170mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X170-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X170-30S
The AirTAC SIJ32X170-30S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. The direct replacement is the SAIJ32X170-30S, retaining the 32mm bore, 170mm nominal stroke, G1/8 port, and M10x1.25 rod thread. An external stop screw lets you trim the extend stroke by up to 30mm on-site, yielding a usable 140-170mm stroke. The stop sets the end position but is not a load lock; use an external rod lock or SAIL/BSAI variant for held loads.
The SAIJ upgrade introduces an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X170-30S Is Used
Diverter Gate Positioning
Trimming the extend stroke by up to 30mm on-site allows precise calibration of diverter gates without machining spacers.
Variable Depth Sealing Heads
Adjustable end-positioning accommodates different carton depths on a packaging line using the 140-170mm usable stroke.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X170-30S with the SAIJ32X170-30S
To replace the discontinued SIJ32X170-30S, order the direct replacement SAIJ32X170-30S, which matches the ISO 15552 mounting interface, 30mm adjust window, and magnet. Select the 30mm adjust window if your extend stroke needs 140-170mm on-site tuning. Mounting options include FA, LB, and TC brackets. The -S magnet suits legacy CS1-B/DS1-B sensors. For strokes of 300mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X170-30S
- ✓ 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 SIJ32X170-30S FAQ
Yes, the SIJ32X170-30S is discontinued. The direct replacement is the SAIJ32X170-30S. It shares the same ISO 15552 interface, 32mm bore, 170mm stroke, 30mm adjust window, G1/8 port, and mounting options, while adding an upgraded piston seal.
The external stop screw window is 30mm, allowing the extend stroke to be shortened from the 170mm nominal maximum down to 140mm. The stop sets end position and is not a load lock.
