This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X150-40, 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 SIJ100X150-40
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X150-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 150mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X150-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-40
The AirTAC SIJ100X150-40 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100mm bore and 150mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 40mm on-site, yielding a usable 110-150mm extension window. The direct replacement is the SAIJ100X150-40, matching the interface, force, and mounting.
The SAIJ upgrade incorporates a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note this SKU lacks a magnet (-S) and cannot take a switch. The stop screw sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-40 Is Used
Press Fit Tuning
Allows precise on-site adjustment of the extend stroke up to 40mm to set exact pressing depths for bearings without machining custom spacers.
Variable Transfer Stops
Adjusts the extend position on packaging lines to handle different carton sizes on the fly, using the 110-150mm stroke window.
End-of-Line Positioning
Dials in the final end position for varying product heights at a palletizing station, ensuring correct contact without reprogramming logic.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X150-40 with the SAIJ100X150-40
To replace the discontinued SIJ100X150-40, order the direct replacement SAIJ100X150-40, keeping the same ISO 15552 mounting interface and G1/2 port. Choose the 40mm adjust window if your extend stroke needs on-site tuning between 110-150mm. Mounting options include FA, LB, and TC. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For strokes >=300mm, verify side-load tolerance to prevent guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X150-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
