This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X225-75, 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 SIJ80X225-75
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-75 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 SAIJ80X225-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-75
The AirTAC SIJ80X225-75 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 75 mm on-site, yielding a usable 150-225 mm stroke. The 80 mm bore uses a G3/8 port, M20x1.5 rod thread, and 36 mm adjustable cushions.
The direct replacement is the SAIJ80X225-75, matching the interface, force, and port. The SAIJ family uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure. Note: this SKU lacks a magnet (-S) so it cannot take a switch.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-75 Is Used
Variable Pitch Indexing
Trimming the extend stroke by up to 75 mm on-site allows a single cylinder to drive multiple varying pitch lengths without swapping the entire actuator assembly.
Adjustable Transfer Pusher
Fine-tune the pusher end position between 150 and 225 mm to accommodate different package sizes on the fly, ensuring precise placement without mechanical spacers.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X225-75 with the SAIJ80X225-75
To replace the discontinued SIJ80X225-75, order the direct replacement SAIJ80X225-75. The 75 mm adjust window is ideal if your end position needs on-site tuning between 150 and 225 mm. Reuse your FA, LB, or TC ISO 15552 mounts. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; confirm external sensing needs. The external stop sets end position but is not a lock; for held loads use an external rod lock or SAIL/BSAI variant. For stroke lengths over 300 mm, carefully manage side loading.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X225-75
- ✓ 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 SIJ80X225-75 FAQ
Yes, the SIJ80X225-75 is discontinued. The direct replacement is the SAIJ80X225-75.
The external stop screw provides a 75 mm adjust window, shortening the 225 mm nominal extend stroke down to 150 mm. The stop sets end position and is not a load lock.
