This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X600-75S, 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 SIJ80X600-75S
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-75S 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 SAIJ80X600-75S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-75S
The AirTAC SIJ80X600-75S is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 600 mm nominal stroke and a built-in piston magnet (-S). An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable 525-600 mm window. This SIJ model is discontinued; the direct replacement is the SAIJ80X600-75S, preserving the interface, force, and adjust window.
The SAIJ upgrade uses an improved two-piece Y-shaped piston seal for lower start-up pressure and longer life. The stop screw sets end position but is not a lock; cylinders drift on air loss, so use an external rod lock or SAIL/BSAI variant for held loads.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-75S Is Used
Variable Stroke Pressing
Ideal for light pressing tasks where the 75 mm on-site adjust window allows operators to tune the extend end position precisely without changing the cylinder.
Adjustable Length Diverter
Useful on conveyor lines where product sizes vary; the external stop screw quickly modifies the 525-600 mm extend reach to deflect different packages.
Custom Position Stops
Deployed in material handling setups requiring field-adjustable end stops to accommodate changing pallet dimensions or variable feed lengths.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X600-75S with the SAIJ80X600-75S
To replace the discontinued SIJ80X600-75S, order the direct replacement SAIJ80X600-75S, which keeps the 80 mm bore, 600 mm stroke, 75 mm adjust window, G3/8 port, and ISO 15552 mounting. Select the 75 mm adjust window if you need field tuning of the extend end position. Mounting options include Basic, FA, LB, and TC. The -S suffix indicates a piston magnet for legacy CS1-B/DS1-B switches (the SAIJ uses current switches). For the 600 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X600-75S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
