This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ32X100-100, 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 SIJ32X100-100
The AirTAC SIJ32 Double Rod Adjustable Cylinder SIJ32X100-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø32mm bore and 100mm stroke, G1/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ32X100-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-100
The AirTAC SIJ32X100-100 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 32 mm bore, G1/8 port, and M10x1.25 rod thread. An external stop screw lets you trim the extend stroke by up to 100 mm on-site (usable extend range 0-100 mm), setting the exact end position without needing a custom-length barrel.
Because this SIJ model is discontinued, the direct replacement is the SAIJ32X100-100, which preserves the ISO 15552 mounting interface, bore, stroke, adjust window, and porting. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note that this non-magnetic SKU cannot take a switch, and the external stop is an end-position setter, not a load lock.

Where the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-100 Is Used
Light-duty clamping dial-in
Trimming the extend stroke by up to 100 mm on-site allows operators to fine-tune the exact clamping position for delicate workpieces without swapping cylinders.
Variable transfer push-off
Adjusting the extend stop on the fly accommodates different product sizes on a packaging line, setting a precise ejection point for each run.
Test rig positioning
Setting the end position externally via the stop screw enables repeatable testing strokes at varying lengths without reprogramming a motion controller.
Replacing the Airtac SIJ32 Double Rod Adjustable Cylinder SIJ32X100-100 with the SAIJ32X100-100
To replace the discontinued SIJ32X100-100, order the direct replacement SAIJ32X100-100, reusing your existing FA, LB, or TC ISO 15552 mounts. The 100 mm adjust window means you can set the extend stroke anywhere from 0 to 100 mm on-site, which is ideal for dialling in a precise end position without machining a custom stop. Because this SKU lacks the -S magnet, it cannot accept a legacy CS1-B or DS1-B sensor; add an external sensor bracket if detection is required. For strokes of 300 mm or longer, carefully verify the side-load limits to prevent guide bushing wear. Finally, the stop screw sets end position only—it is not a lock; for held loads, use an external rod lock, a pilot-operated check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ32X100-100
- ✓ 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 SIJ32X100-100 FAQ
Yes, the SIJ32X100-100 is discontinued. The direct replacement is the SAIJ32X100-100, which shares the same ISO 15552 interface, 32 mm bore, 100 mm stroke, 100 mm adjust window, and G1/8 port. The SAIJ family also features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw allows you to shorten the extend stroke by up to 100 mm on-site (usable extend range 0-100 mm). The stop sets end position only and is not a load lock; for held loads, use an external rod lock or the SAIL/BSAI variant.
