This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X225-10S, 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 SIJ80X225-10S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 225mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X225-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-10S
The AirTAC SIJ80X225-10S 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 215-225 mm forward travel out of the 225 mm nominal maximum. This end-of-life unit is replaced by the SAIJ80X225-10S.
The SAIJ direct replacement retains the exact ISO 15552 mounting interface, 25 mm rod, and M20x1.5 thread, but upgrades to a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The stop screw sets the end position but is not a load lock; for held loads use an external rod lock or the SAIL/BSAI variants.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-10S Is Used
Press Fit Calibration
Final insertion depth of bearings requires micro-adjustments; trim the extend stroke by up to 10 mm on-site to dial in the exact 215-225 mm reach without re-mounting the actuator.
Divert Gate Positioning
Sorting lines needing a slightly shortened push stroke to avoid striking passing pallets can field-tune the end position using the external stop screw.
Carton Flap Folding
Adjustable end-positioning allows operators to fine-tune the folding arm travel for varying box widths, ensuring crisp folds without reprogramming the machine.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-10S with the SAIJ80X225-10S
To replace this discontinued SIJ80X225-10S, specify SAIJ80X225-10S for an direct match retaining the G3/8 port, 225 mm stroke, and 10 mm adjust window. Choose the 10 mm adjust window if you only need minor final-position tuning between 215-225 mm. Mounting options include FA, LB, and TC brackets. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches; the SAIJ replacement uses current AirTAC switches. For strokes of 300 mm or longer, verify your side-load limits to prevent rod distortion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X225-10S
- ✓ 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 SIJ80X225-10S FAQ
Yes, the AirTAC SIJ80X225-10S is discontinued. The direct replacement is the SAIJ80X225-10S. It shares the same ISO 15552 interface, 80 mm bore, 225 mm stroke, 10 mm adjust window, G3/8 port, and 25 mm rod, but features an upgraded two Y-shaped one-way piston seal.
The external stop screw offers a 10 mm adjust window, allowing you to shorten the extend stroke from 225 mm down to 215 mm. The stop sets end position and is not a load lock.
