This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X800-30S, 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 SIJ80X800-30S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-30S 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 SAIJ80X800-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-30S
The AirTAC SIJ80X800-30S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 800 mm nominal stroke and a built-in magnetic piston (-S). An external stop screw allows you to trim the extend stroke on-site by up to 30 mm, yielding a usable extend range of 770-800 mm. The stop sets the end position; it is not a load lock. This 80 mm bore uses a G3/8 port, a Ø25 mm rod, and 36 mm adjustable cushions.
The direct replacement is the SAIJ80X800-30S, preserving the ISO 15552 mounting interface, force, and porting. The SAIJ upgrade features a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note that a plain cylinder drifts on air loss; use an external rod lock or SAIL/BSAI variant for load holding.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-30S Is Used
Long-reach pressing
Field-tuning the 770-800 mm extend stop on a press head to accommodate varying material thicknesses without reprogramming the machine cycle.
Transfer diverter
Adjusting the extend end-position by up to 30 mm on-site to perfectly align a pneumatic diverter arm with different conveyor lane widths.
Pallet positioning
Dialing in the exact extend stroke to push pallets into a wrapping station, compensating for minor fixture misalignment.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X800-30S with the SAIJ80X800-30S
To replace the discontinued SIJ80X800-30S, order the direct replacement SAIJ80X800-30S, reusing your existing FA, LB, or TC mounts. The 30 mm adjust window is ideal if your extend stroke needs final on-site tuning between 770 and 800 mm. The -S suffix ensures piston magnet compatibility for legacy CS1-B/DS1-B switches (the SAIJ uses current AirTAC switches). Because the 800 mm stroke is long, account for rod-bending and use external guides to minimize side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X800-30S
- ✓ 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 SIJ80X800-30S FAQ
Yes, the SIJ80X800-30S is discontinued. The direct replacement is the SAIJ80X800-30S. It shares the same ISO 15552 interface, 80 mm bore, 800 mm stroke, 30 mm adjust window, G3/8 port, and mounting options. The SAIJ upgrade adds a two Y-shaped one-way piston seal for longer life and lower start-up pressure.
The external stop screw window is 30 mm, allowing you to shorten the 800 mm nominal extend stroke down to 770 mm on-site. The stop sets end position and is not a load lock.
