This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X80-40, 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 SIJ100X80-40
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X80-40 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 SAIJ100X80-40, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-40
The AirTAC SIJ100X80-40 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 80 mm maximum extend stroke. An external stop screw lets you trim the extend stroke by up to 40 mm on-site, yielding a usable 40-80 mm range. The stop sets the end position but is not a load lock.
The direct replacement is the SAIJ100X80-40, matching the ISO 15552 interface, bore, force, and mounting. The SAIJ family uses an upgraded two-piece Y-shaped piston seal for lower start-up pressure and longer life. This non-magnetic SKU cannot take a switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-40 Is Used
Press Fit Tuning
Allows on-site stroke reduction up to 40 mm to dial in exact press depth for varying insert heights without machining spacers.
Variable Length Diverter
Adjusts the extend endpoint on a sorting gate to accommodate changing package sizes on the fly.
Adjustable End Stop
Sets precise mechanical end positions for pallet positioning pins where nominal 80 mm travel must be trimmed down to 40 mm.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X80-40 with the SAIJ100X80-40
Replace the discontinued SIJ100X80-40 directly with the SAIJ100X80-40 (insert A after the leading S), retaining the same FA, LB, or TC mounts and G1/2 port. Choose the 40 mm adjust window if your end-position needs field tuning between 40 and 80 mm. Because this SKU lacks the -S suffix, it cannot accept a magnetic switch; add -S for legacy CS1-B/DS1-B sensing. For strokes >=300 mm, verify side-load guidance to prevent rod binding. The external stop is not a lock; for held loads use SAIL, BSAI, or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X80-40
- ✓ 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 SIJ100X80-40 FAQ
Yes, the SIJ100X80-40 is discontinued. The direct replacement is the SAIJ100X80-40, offering the same ISO 15552 interface, 80 mm stroke, 40 mm adjust window, and G1/2 port.
The 40 mm adjust window allows trimming the 80 mm extend stroke down to 40 mm on-site. The stop sets end position but is not a load lock.
