This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X75-10S, 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 SIJ80X75-10S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 75mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X75-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-10S
The AirTAC SIJ80X75-10S 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 10mm on-site, giving a usable 65-75mm stroke (75mm is the maximum). The direct replacement is the SAIJ80X75-10S, matching the interface, force, and mounting.
The SAIJ upgrade features an improved two-piece Y-shaped piston seal for lower start-up pressure and longer life. The -S suffix means a piston magnet is present for legacy CS1-B/DS1-B switches. The stop screw sets end position only; it is not a load lock, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-10S Is Used
Clamping Position Trimming
Allows operators to fine-tune the extend end position by up to 10mm on-site to accommodate material thickness variations without changing the cylinder.
Transfer Diverter Setup
Provides adjustable end-stop positioning for a 75mm stroke diverter gate, letting maintenance crews dial in the exact routing angle on the conveyor line.
Product Pusher Adjustment
Enables a 10mm reduction in the pusher extend stroke to handle slightly smaller carton formats on the fly, ensuring positive contact without repositioning the mount.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X75-10S with the SAIJ80X75-10S
To replace the discontinued SIJ80X75-10S, map directly to the SAIJ80X75-10S (insert A after the leading S), keeping the 80mm bore, 75mm stroke, 10mm adjust window, and -S magnet. Choose the 10mm adjust window when you need minor field tuning of the extend end position. Mounting options include FA, LB, and TC brackets. The -S suffix ensures compatibility with legacy CS1-B/DS1-B sensors (current AirTAC switches on the SAIJ). Because the 75mm stroke is under 300mm, side-load rod deflection is minimal.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X75-10S
- ✓ 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 SIJ80X75-10S FAQ
Yes, the SIJ80X75-10S is discontinued. The direct replacement is the SAIJ80X75-10S. It shares the same ISO 15552 interface, 80mm bore, 75mm stroke, 10mm adjust window, G3/8 port, and mounting options, but uses an upgraded piston seal.
The external stop screw provides a 10mm adjust window, shortening the extend stroke from the 75mm maximum down to 65mm. The stop sets end position and is not a load lock.
