This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ100X700-20, 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 SIJ100X700-20
The AirTAC SIJ100 Double Rod Adjustable Cylinder SIJ100X700-20 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 SAIJ100X700-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-20
The AirTAC SIJ100X700-20 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 100 mm bore and 700 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 20 mm on-site, yielding a usable 680-700 mm extension window. This SIJ model is discontinued; the direct replacement is the SAIJ100X700-20, which preserves the interface, force, and mounting.
The SAIJ successor incorporates an upgraded two Y-shaped one-way piston seal for low start-up pressure and extended life, while operating across 0.15-1.0 MPa and -20 to +70 C. The external stop sets the end position but is not a load lock; the piston drifts on air loss, so use an external rod lock for held loads. This non-magnetic SKU cannot accept a switch.

Where the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-20 Is Used
Press Tonnage Calibration
Needs field stroke tuning to dial in the exact 680-700 mm extend contact point during light assembly press setups, preventing overtravel.
Divertor Arm Positioning
Requires adjustable end-position tuning to accommodate varying package sizes on the fly without reprogramming the machine logic.
Pallet Stopper Gate
Demands on-site extend trimming to fine-tune the stopping distance for different pallet depths before the 36 mm cushion decelerates the load.
Replacing the Airtac SIJ100 Double Rod Adjustable Cylinder SIJ100X700-20 with the SAIJ100X700-20
To replace the discontinued SIJ100X700-20, order the direct replacement SAIJ100X700-20, keeping the 700 mm maximum stroke and 20 mm adjust window. Choose the 20 mm adjust window if you need precise 680-700 mm extend tuning on-site. Mounting options include Basic, FA, LB, and TC using the ISO 15552 interface. Because this SKU lacks the -S magnet, it cannot accept a magnetic switch. For the 700 mm stroke, use external guides to prevent rod bending and manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ100X700-20
- ✓ 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 SIJ100X700-20 FAQ
Yes, the SIJ100X700-20 is discontinued. The direct replacement is the SAIJ100X700-20, offering the same ISO 15552 interface, 100 mm bore, 700 mm stroke, 20 mm adjust window, and G1/2 port.
The external stop screw provides a 20 mm adjust window, allowing the extend stroke to be shortened from 700 mm down to 680 mm.
