This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X800-10, 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 SIJ80X800-10
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 800mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X800-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-10
The AirTAC SIJ80X800-10 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a nominal 800 mm stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 790-800 mm window. The 80 mm bore features a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions. The direct replacement is the SAIJ80X800-10, sharing the same interface, force, and mounting.
The stop screw sets the end position but is not a load lock; the cylinder drifts on air loss. The SAIJ upgrade uses a two Y-shaped one-way piston seal for low start-up pressure and long life. Because this SKU lacks a -S magnet, it cannot take a magnetic switch.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-10 Is Used
Press Stroke Tuning
Ideal for light assembly presses needing exact 790-800 mm extend endpoints to seat components without bottoming out the tooling.
Transfer Line Diverter
Useful on long-stroke transfer lines where a 10 mm external stop adjustment compensates for minor fixture misalignment over an 800 mm run.
Pallet Positioning Stop
Acts as an adjustable physical end-stop for pallets, allowing 10 mm of field tuning to dial in the exact resting position.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-10 with the SAIJ80X800-10
To replace the discontinued SIJ80X800-10, specify the direct replacement SAIJ80X800-10, reusing your existing FA, LB, or TC ISO 15552 mounts. The 10 mm adjust window is ideal if you only need to fine-tune the extend end position within a 790-800 mm range. If you need more on-site stroke trimming, consider a larger adjust window. Because the 800 mm stroke is long, verify side-load limits and use external guides to prevent rod bending. This non-magnetic SKU cannot support legacy CS1-B/DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X800-10
- ✓ 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 SIJ80X800-10 FAQ
Yes, the SIJ80X800-10 is discontinued. The direct replacement is the SAIJ80X800-10, which shares the same ISO 15552 interface, 80 mm bore, 800 mm stroke, 10 mm adjust window, G3/8 port, and mounting options.
The external stop screw allows you to trim the extend stroke by up to 10 mm on-site (usable 790-800 mm). The stop sets end position only; it is not a load lock.
