This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X500-100S, 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 SIJ80X500-100S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-100S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 500mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X500-100S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-100S
The AirTAC SIJ80X500-100S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 500 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 100 mm on-site, yielding a usable 400-500 mm window. The 80 mm bore uses a G3/8 port, a 25 mm rod, and 36 mm adjustable cushions. This SIJ model is discontinued; the direct replacement is the SAIJ80X500-100S, sharing the same interface, force, and mounting.
The SAIJ upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. Remember the stop screw sets end position only; it is not a load lock, so use an external rod lock for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-100S Is Used
Variable Press Stroke
Assembly presses needing field stroke tuning to accommodate multiple part heights without swapping cylinders.
Adjustable Diverter
Routing actuators on packaging lines where the extend end position requires periodic 100 mm retraction tuning.
Variable Depth Stops
Palletizing end-effectors that need precise extend-stop adjustments for varying carton depths on the fly.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-100S with the SAIJ80X500-100S
To replace the discontinued SIJ80X500-100S, specify SAIJ80X500-100S directly—it is a direct match for the ISO 15552 dimensions, G3/8 port, and 100 mm adjust window. Choose the 100 mm adjust window if your end-position tuning requires the full 400-500 mm range. Mounting options include FA, LB, and TC brackets. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches. Because the stroke is 500 mm, ensure external guides carry side loads to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X500-100S
- ✓ 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 SIJ80X500-100S FAQ
Yes, the SIJ80X500-100S is discontinued. The direct replacement is the SAIJ80X500-100S. It shares the identical ISO 15552 interface, 80 mm bore, 500 mm stroke, 100 mm adjust window, G3/8 port, and mounting options, but features an upgraded piston seal.
The external stop screw provides a 100 mm adjust window, allowing the 500 mm extend stroke to be shortened on-site down to 400 mm. The stop sets end position only and does not lock the load.
