This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X900-75, 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 SIJ80X900-75
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 900mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X900-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-75
The AirTAC SIJ80X900-75 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued. Its external stop screw lets you trim the extend stroke by up to 75 mm on-site, giving a usable extend range of 825-900 mm (the 900 mm nominal stroke is the maximum). This 80 mm bore uses a G3/8 port, a Ø25 mm rod with an M20x1.5 thread, and 36 mm adjustable cushions. The direct replacement is the SAIJ80X900-75, matching the interface, bore, stroke, force, and mounting.
The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. This SKU has no -S magnet and cannot take a switch. Note the stop screw sets end position only; it is not a lock, and on air loss the piston drifts. For held loads use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-75 Is Used
Sorter Diverter Setup
Tuning the diverter arm reach on-site by up to 75 mm to accommodate varying package widths without changing the entire cylinder mount.
Press Positioning
Adjusting the extend end position in a light assembly press where the working gap requires precise field calibration across a 825-900 mm range.
Pallet Stop Gate
Calibrating a stop gate for different pallet depths, using the external screw to shorten the extend stroke exactly to the required limit.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X900-75 with the SAIJ80X900-75
To replace the discontinued SIJ80X900-75, order the direct replacement SAIJ80X900-75, keeping the identical ISO 15552 mounting interface, G3/8 port, and 75 mm adjust window. Choose the 75 mm adjust window if your extend stroke needs on-site tuning between 825 and 900 mm. Mounting options include Basic, FA, LB, and TC. Because this SKU lacks the -S magnet, it cannot accept a magnetic switch; confirm sensing needs before ordering. Finally, at a 900 mm stroke, mind the side-load and rod-bending risks—use external guides to support the rod.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X900-75
- ✓ 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 SIJ80X900-75 FAQ
Yes, the SIJ80X900-75 is discontinued. The direct replacement is the SAIJ80X900-75. It shares the same ISO 15552 interface, 80 mm bore, 900 mm nominal stroke, 75 mm adjust window, G3/8 port, and mounting options, while adding an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life.
The external stop screw allows you to trim the extend stroke by up to 75 mm on-site, yielding a usable extend range of 825-900 mm. The stop sets end position only; it is not a load lock.
