This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X80-30S, 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 SIJ100X80-30S
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X80-30S 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 SAIJ100X80-30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-30S
The AirTAC SIJ100X80-30S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 30 mm on-site, giving a usable forward range of 50-80 mm from the 80 mm nominal maximum.
As this SIJ series is end-of-life, the direct replacement is the SAIJ100X80-30S, preserving the ISO 15552 mounting interface, bore, stroke, adjust window, and force. The SAIJ upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. Note the stop screw sets end position but is not a load lock; use SAIL or BSAI for held loads.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-30S Is Used
Press Fit Tuning
Allows operators to dial in the exact 50-80 mm extend position for pressing bearings without machining hard stops.
Variable Length Diverter
Adjusts the extend stroke on-site to deflect varying package sizes on a sorting line.
Carton Sealing Head
Trims the forward stroke by up to 30 mm to accommodate different flap heights dynamically.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-30S with the SAIJ100X80-30S
To replace the discontinued SIJ100X80-30S, order the direct replacement SAIJ100X80-30S, which matches the 100 mm bore, 80 mm stroke, 30 mm adjust window, G1/2 port, and ISO 15552 mounting. Choose the 30 mm adjust window if your end-position tuning falls within a 50-80 mm extend range. Reuse existing FA, LB, or TC mounts. The -S suffix ensures a piston magnet for legacy CS1-B/DS1-B switches (current AirTAC switches are used on the SAIJ). For strokes of 300 mm or longer, verify side-load guidance to prevent rod wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X80-30S
- ✓ 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 SIJ100X80-30S FAQ
Yes, the SIJ100X80-30S is discontinued. The direct replacement is the SAIJ100X80-30S. It shares the same ISO 15552 interface, 100 mm bore, 80 mm stroke, 30 mm adjust window, G1/2 port, and mounting. The SAIJ family also adds an upgraded piston seal and lock variants like SAIL and BSAI.
The external stop screw allows trimming the extend stroke by up to 30 mm on-site, yielding a usable extend range of 50-80 mm. The stop sets end position and is not a load lock.
