This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X80-10S, 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 SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 80mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X80-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10S
The AirTAC SIJ100X80-10S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 80 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 70-80 mm extension window. The direct replacement is the SAIJ100X80-10S, retaining the same interface, force, and mounting.
The SAIJ successor incorporates an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. The stop screw strictly sets the end position; it is not a lock. The -S suffix indicates a built-in piston magnet for legacy CS1-B/DS1-B switches.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10S Is Used
Press Fit Calibration
Fine-tune the 70-80 mm extend stroke on-site to dial in exact insertion depths for bearing press fits without re-engineering the fixture.
Divertor Gate Adjustment
Adjust the extend stop by up to 10 mm to alter the actuator reach on a sorting line, accommodating varying package profiles on the fly.
Sealing Head Height
Trim the extend stroke to set the precise downward travel of a sealing jaw, ensuring consistent contact pressure across different material thicknesses.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10S with the SAIJ100X80-10S
To replace the discontinued SIJ100X80-10S, order the direct replacement SAIJ100X80-10S, matching the 100 mm bore, 80 mm stroke, 10 mm adjust window, and G1/2 port. Choose the 10 mm adjust window if your application requires precise 70-80 mm extend tuning. Mounting options include FA, LB, and TC brackets. The -S suffix ensures piston magnet compatibility for position sensing. For stroke lengths of 300 mm or greater, verify side-load limits to prevent excessive rod bearing wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X80-10S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-10S FAQ
Yes, the SIJ100X80-10S is discontinued. The direct replacement is the SAIJ100X80-10S, which shares the identical ISO 15552 interface, 100 mm bore, 80 mm stroke, 10 mm adjust window, G1/2 port, and mounting options. The SAIJ family also features an upgraded piston seal for longer life.
The external stop screw allows you to trim the extend stroke by up to 10 mm on-site, giving a usable 70-80 mm extend window. The stop sets end position and is not a load lock.
