This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ80X160-30, 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 SIJ80X160-30
The AirTAC SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30 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 SAIJ80X160-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30
The AirTAC SIJ80X160-30 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder, now discontinued and directly replaced by the SAIJ80X160-30. It features an 80 mm bore, a Ø25 mm piston rod, and a G3/8 air port. The external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable extend range of 130-160 mm. The nominal 160 mm stroke remains the maximum, and the stop screw simply sets the end position—it is not a load lock.
The direct replacement SAIJ80X160-30 retains the exact ISO 15552 mounting interface, bore, stroke, and force, while upgrading to a two-piece Y-shaped one-way piston seal for lower start-up pressure and longer life. This plain SKU lacks a magnet (-S omitted), so it cannot accept a magnetic switch. Note that a standard cylinder drifts on air loss; for held loads, use an external rod lock, pilot-operated check valve, or the SAIL/BSAI lock variants.

Where the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30 Is Used
Variable Stroke Clamping
Ideal for clamping stations where part dimensions vary, using the 30 mm on-site extend trim to set precise end positions without re-plumbing the G3/8 air lines.
Adjustable Transfer Stops
Deployed as a transfer stop on conveyor lines, allowing operators to shorten the extend stroke by up to 30 mm to accommodate different package heights on the fly.
Customizable Sorting Diverter
Used in sorting diverters where the 130-160 mm usable extend range must be tuned precisely to the lane width, ensuring accurate routing without repositioning the ISO 15552 mounts.
Replacing the Airtac SIJ80 Dual Axis Adjustable Cylinder SIJ80X160-30 with the SAIJ80X160-30
To replace the discontinued SIJ80X160-30, order the direct replacement SAIJ80X160-30, keeping the identical 80 mm bore, 160 mm stroke, 30 mm adjust window, G3/8 port, and ISO 15552 mounting dimensions. Choose the 30 mm adjust window if your field tuning requires trimming the extend stroke by up to 30 mm on-site (usable range 130-160 mm). Mounting options include Basic, FA, LB, and TC. Because this SKU lacks the -S suffix, it has no magnet and cannot use legacy CS1-B/DS1-B sensors. For strokes of 300 mm or longer, verify side-load limits to prevent excessive rod wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ80X160-30
- ✓ 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 SIJ80X160-30 FAQ
Yes, the SIJ80X160-30 is discontinued. The direct replacement is the SAIJ80X160-30. It shares the same ISO 15552 interface, 80 mm bore, 160 mm stroke, 30 mm adjust window, G3/8 port, and mounting options, while adding an upgraded two-piece Y-shaped piston seal.
The external stop screw provides a 30 mm adjust window, allowing you to trim the nominal 160 mm extend stroke down to 130 mm on-site. The stop sets end position only and does not lock the load.
