This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X160-100, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X160-100
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X160-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 160mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X160-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X160-100
The AirTAC SIJ100X160-100 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 160 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 60-160 mm extension. The direct replacement is the SAIJ100X160-100, matching the G1/2 port, M20x1.5 rod thread, 36 mm cushions, and mounting interfaces without any mechanical redesign.
The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this SKU lacks a -S magnet, so it cannot carry a magnetic switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X160-100 Is Used
Variable Stroke Pressing
Dialing in the exact contact position on an assembly press, where the 100 mm stop screw window allows precise final height tuning without changing the cylinder body.
Adjustable Diverter Arm
Routing products on a conveyor by trimming the extend stroke on-site to accommodate different package widths, using the 60-160 mm usable extension range.
Custom End-Stop Positioning
Setting a specific mechanical end position for a pallet stopper, relying on the external screw to set the exact 100 mm shortening limit dynamically.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X160-100 with the SAIJ100X160-100
To replace the discontinued SIJ100X160-100, order the direct replacement SAIJ100X160-100, which preserves the ISO 15552 mounting interface and 100 mm adjust window. Select the -100 mm adjust window if your application requires field tuning the extend stroke between 60 and 160 mm. Mounting options include FA, LB, and TC brackets. Because this SKU has no -S suffix, it cannot accept legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, verify your side-load limits to prevent guide bushing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X160-100
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X160-100 FAQ
Yes, the SIJ100X160-100 is discontinued. The direct replacement is the SAIJ100X160-100. It shares the same ISO 15552 interface, 100 mm bore, 160 mm stroke, 100 mm adjust window, G1/2 port, and mounting options, while adding an upgraded piston seal.
The external stop screw provides a 100 mm adjust window, allowing the extend stroke to be shortened from the 160 mm maximum down to 60 mm. The stop sets end position only; it is not a load lock.
