This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X600-10S, 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 SIJ80X600-10S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X600-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-10S
The AirTAC SIJ80X600-10S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder featuring a 600 mm nominal stroke and a G3/8 port. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 590-600 mm window. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches.
This SIJ model is discontinued; the direct replacement is the SAIJ80X600-10S, which retains the same ISO 15552 mounting interface, bore, and force. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. 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 SIJ80X600-10S Is Used
Press Fit Tuning
Allows precise 590-600 mm extend adjustment for pressing bearings where a fixed 600 mm stroke risks over-travel.
Transfer Diverter
Fine-tunes the extend end position on-site to accommodate varying package sizes without remounting the actuator.
Pallet Stop Gate
Provides a 10 mm field adjustment window to dial in the exact stopping point for pallets on a 600 mm extension.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-10S with the SAIJ80X600-10S
To replace the discontinued SIJ80X600-10S, order the direct replacement SAIJ80X600-10S, ensuring your legacy CS1-B/DS1-B sensors are updated to current AirTAC switches. Choose the 10 mm adjust window if you need minor 590-600 mm extend trimming rather than a fixed stop. FA, LB, or TC mountings reuse your existing ISO 15552 interface. Because the 600 mm stroke exceeds 300 mm, account for rod-bending and use external guides to manage side loads. The stop screw sets position only; for load holding on air loss, select a pilot-operated check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X600-10S
- ✓ 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 SIJ80X600-10S FAQ
Yes, the SIJ80X600-10S is discontinued. The direct replacement is the SAIJ80X600-10S, offering the same ISO 15552 interface, 80 mm bore, 600 mm stroke, 10 mm adjust window, and G3/8 port. The SAIJ features an upgraded two Y-shaped one-way piston seal for longer life.
The external stop screw window is 10 mm, allowing you to trim the extend stroke from 600 mm down to 590 mm. The stop sets end position and is not a load lock.
