This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X500-10S, 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 SIJ80X500-10S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-10S 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 SAIJ80X500-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-10S
The AirTAC SIJ80X500-10S is a 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, yielding a usable 490-500 mm stroke from the 500 mm nominal maximum. The 80 mm bore features a 25 mm rod, M20x1.5 thread, G3/8 port, and 36 mm adjustable cushions. This SIJ model is discontinued; the direct replacement is the SAIJ80X500-10S.
The SAIJ successor retains the ISO 15552 mounting interface and introduces an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. The stop screw sets the end position but is not a load lock; drift occurs on air loss. The -S suffix provides a piston magnet for legacy CS1-B/DS1-B sensors.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-10S Is Used
Press Fit Calibration
Needs field stroke tuning to dial in the exact 490-500 mm extend position for seating bearings without over-traveling.
Pallet Stopper Gate
Requires trimming the extend stroke by up to 10 mm on-site to align the stop gate perfectly with varying pallet heights.
Packaging Flap Closure
Needs adjustable end-position tuning to ensure carton flaps close securely without crushing the contents.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X500-10S with the SAIJ80X500-10S
To replace the discontinued SIJ80X500-10S, order the direct replacement SAIJ80X500-10S, matching the 80 mm bore, 500 mm stroke, 10 mm adjust window, and G3/8 port. Choose the 10 mm adjust window if you need micro-corrections to the extend end position. Mounting options include FA, LB, and TC brackets. The -S suffix ensures a piston magnet is present. Because the 500 mm stroke is long, verify side-load conditions and use external guides to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X500-10S
- ✓ 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 SIJ80X500-10S FAQ
Yes, the SIJ80X500-10S is discontinued. The direct replacement is the SAIJ80X500-10S, which shares the same ISO 15552 interface, 80 mm bore, 500 mm stroke, 10 mm adjust window, and G3/8 port.
The external stop screw provides a 10 mm adjust window (usable extend stroke 490-500 mm).
