This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X160-75, 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 SIJ80X160-75
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-75 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ80X160-75, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-75
The AirTAC SIJ80X160-75 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with an 80 mm bore and 160 mm nominal stroke. An external stop screw lets you trim the extend stroke by up to 75 mm on-site, yielding a usable forward travel of 85 to 160 mm. As this SIJ is end-of-life, the direct replacement is the SAIJ80X160-75, retaining the same interface, force, and adjust window.
The SAIJ successor features an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. Because the stop screw only sets the end position, it is not a load lock; use an external rod lock or pilot-operated check valve for held loads. This non-magnetic SKU cannot take a switch.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-75 Is Used
Variable Pitch Forming
Bending stations that need to alter the extend depth by up to 75 mm for different material thicknesses without swapping the entire actuator.
Adjustable Transfer Stops
Diverting packages of varying sizes on a line by tuning the extend stroke on-site between 85 and 160 mm to act as a physical barrier.
Tiered Pallet Positioning
Pressing or locating pallets at distinct heights where the final lower position must be precisely dialed in via the external stop screw.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-75 with the SAIJ80X160-75
To replace the discontinued SIJ80X160-75, order the SAIJ80X160-75 direct, keeping the same FA, LB, or TC ISO 15552 mounts and G3/8 port. Select the 75 mm adjust window if your fixture requires trimming the 160 mm nominal extend down to a minimum of 85 mm. Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors; confirm if position feedback is required. For strokes of 300 mm or longer, carefully manage side-load guiding to prevent rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-75
- ✓ 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 SIJ80X160-75 FAQ
Yes, the SIJ80X160-75 is discontinued. The direct replacement is the SAIJ80X160-75, which shares the identical ISO 15552 mounting interface, 80 mm bore, 160 mm stroke, 75 mm adjust window, and G3/8 port. The SAIJ family also adds an upgraded two Y-shaped one-way piston seal for longer life.
The theoretical max is 513 kgf at 1.0 MPa. The external stop screw provides a 75 mm adjustment window, allowing you to shorten the 160 mm extend stroke down to 85 mm on-site. The stop sets end position only; it is not a load lock.
