This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X200-75, 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 SIJ80X200-75
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X200-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-75
The AirTAC SIJ80X200-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. A 200 mm nominal extend stroke is shortened on-site by an external stop screw, trimming up to 75 mm to yield a 125-200 mm usable window. The 80 mm bore uses a G3/8 port, a Ø25 mm rod, and 36 mm adjustable cushions. The direct replacement is the SAIJ80X200-75, matching the ISO 15552 mounting interface, force, and stroke.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The stop screw sets end position only; it is not a load lock.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-75 Is Used
Variable Depth Drilling
Adjusts the extend stroke on-site to set precise drilling depths for different material thicknesses without swapping cylinders.
Variable Position Diverter
Tunes the extend stop to deflect varying package sizes on a conveyor line, allowing rapid format changeovers.
Adjustable Height Stops
Sets different end-stop positions for palletizing tasks, accommodating multiple pallet heights with a single actuator.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X200-75 with the SAIJ80X200-75
To replace the discontinued SIJ80X200-75, order the exact direct replacement SAIJ80X200-75, keeping the 200 mm nominal stroke and 75 mm adjust window. Choose the 75 mm window when you need field tuning from 125 to 200 mm; a smaller window gives a stiffer stop. Mounting reuses ISO 15552 FA, LB, or TC interfaces. This SKU lacks the -S magnet, so it cannot take a magnetic switch. For stroke lengths >=300 mm, verify side-load limits to prevent rod binding. The stop screw sets end position only; for load holding without live air, use an external rod lock or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X200-75
- ✓ 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 SIJ80X200-75 FAQ
Yes, the SIJ80X200-75 is discontinued. The direct replacement is the SAIJ80X200-75. It matches the ISO 15552 interface, 80 mm bore, 200 mm stroke, 75 mm adjust window, G3/8 port, and mounting dimensions, while adding an upgraded piston seal.
The external stop screw trims the extend stroke by up to 75 mm on-site, giving a 125-200 mm usable window. The stop sets end position only; it is not a load lock.
