This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X700-40, 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 SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-40
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-40 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X700-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-40
The AirTAC SIJ80X700-40 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 40 mm on-site, giving a usable 660-700 mm window from the 700 mm nominal maximum. The direct replacement is the SAIJ80X700-40, matching the interface, force, and M20x1.5 rod thread.
The SAIJ upgrade utilizes an improved two-piece Y-shaped piston seal for lower start-up pressure and longer life. Note this SKU lacks a magnet (-S omitted), so it cannot accept a reed switch. The stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-40 Is Used
Variable Depth Forming
Adjusting the 40 mm extend stop on-site lets a press tune material bend depth without swapping cylinders.
Variable Length Diverter
Trimming the extend stroke by up to 40 mm adapts a diverting arm to different package sizes on the fly.
Adjustable Stop Positioning
A pallet stop gate uses the 660-700 mm window to accommodate varying load lengths on the line.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-40 with the SAIJ80X700-40
To replace the SIJ80X700-40, order the SAIJ80X700-40 direct, reusing your FA, LB, or TC ISO 15552 mounts. Select the 40 mm adjust window when you need 660-700 mm extend reach. Because the 700 mm stroke increases rod-bending risk, ensure external guides handle side loads. Without a -S magnet, this SKU cannot support legacy CS1-B/DS1-B sensors. For load-holding during air loss, the stop screw only sets position; add an external rod lock, pilot-operated check valve, or use the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X700-40
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
