This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X700-10, 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 SIJ80X700-10
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-10 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 SAIJ80X700-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-10
The AirTAC SIJ80X700-10 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 10 mm on-site, giving a usable 690-700 mm window (700 mm nominal maximum). The 80 mm bore features a 25 mm rod, M20x1.5 thread, 36 mm adjustable cushions, and a G3/8 port. This SKU lacks a magnet (-S omitted) and cannot accept a magnetic switch.
The direct replacement is the SAIJ80X700-10, retaining the same ISO 15552 mounting interface, force, and adjust window. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Note the stop screw sets end position only; it is not a load lock. On air loss, the piston drifts, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-10 Is Used
Press Fit Tuning
Dialing in a 690-700 mm extend endpoint on-site to seat bearings without overstressing the tooling, leveraging the 10 mm stop screw window.
Pallet Stop Adjustment
Fine-tuning the extend position of a diverter arm by up to 10 mm to accommodate varying pallet widths without re-mounting the cylinder.
Packaging Flap Folding
Adjusting the extend stroke by 10 mm on-site to fold carton flaps of slightly differing heights, ensuring a clean seal without machine rebuilds.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-10 with the SAIJ80X700-10
To replace this discontinued SIJ80X700-10, order the direct replacement SAIJ80X700-10, keeping the 700 mm maximum stroke and 10 mm adjust window. Reuse existing FA, LB, or TC mounts via the ISO 15552 interface. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; confirm if a magnet is required. With a 700 mm stroke, minimize side-load and rod-bending by using external guides to support the rod.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X700-10
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X700-10 FAQ
Yes, the SIJ80X700-10 is discontinued. The direct replacement is the SAIJ80X700-10, which shares the identical ISO 15552 interface, 700 mm stroke, 10 mm adjust window, and G3/8 port. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw allows you to trim the extend stroke by up to 10 mm on-site (usable 690-700 mm). The stop sets end position only and is not a load lock.
