This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X700-100, 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 SIJ100X700-100
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X700-100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ100X700-100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-100
The AirTAC SIJ100X700-100 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 100 mm on-site, yielding a usable 600-700 mm extension from the 700 mm nominal maximum. It features a Ø25 mm rod, M20x1.5 rod thread, and a G1/2 port.
The direct replacement is the SAIJ100X700-100, reusing your existing ISO 15552 mounting interface. The SAIJ family upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note: this SKU lacks a magnet (-S) and cannot take a switch. The stop screw sets end position but is not a load lock; use an external rod lock for held loads.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-100 Is Used
Press Fit Tuning
Needs field stroke tuning to dial in exact insertion depth on-site without re-mounting the actuator.
Variable Length Diverter
Requires adjusting the extend position to handle different package sizes on a single sorting line.
Adjustable Stopper Gate
Uses the external stop screw to fine-tune the end position for varying pallet widths at a packing station.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-100 with the SAIJ100X700-100
To replace this discontinued model, swap directly to the SAIJ100X700-100, keeping the identical ISO 15552 mounting and G1/2 port. Choose the 100 mm adjust window if you need to trim the extend stroke by up to 100 mm on-site. Mounting options include FA, LB, and TC. Because this SKU has no -S magnet, it cannot support legacy CS1-B/DS1-B sensors. For the 700 mm stroke, add external guides to prevent rod bending and manage side loads. The stop screw sets end position but is not a lock; for held loads use SAIL/BSAI or an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X700-100
- ✓ 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 SIJ100X700-100 FAQ
Yes, the SIJ100X700-100 is discontinued. The direct replacement is the SAIJ100X700-100, which shares the same ISO 15552 interface, 700 mm stroke, 100 mm adjust window, and G1/2 port. The SAIJ family also adds an upgraded piston seal.
The external stop screw window is 100 mm, allowing you to trim the extend stroke from 700 mm down to 600 mm. The stop sets end position and is not a load lock.
