This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X700-30, 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 SIJ63 Double Rod Adjustable Cylinder SIJ63X700-30
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X700-30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 700mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X700-30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-30
The AirTAC SIJ63X700-30 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 670-700 mm window from the 700 mm nominal maximum. The 63 mm bore uses a G3/8 port, M16x1.5 rod thread, and 30 mm adjustable cushions. Because SIJ is end-of-life, the direct replacement is the SAIJ63X700-30, matching the interface, bore, stroke, force, and mounting.
The SAIJ upgrade retains these ratings but uses an upgraded two Y-shaped one-way piston seal for lower start-up pressure and longer life. This non-magnet SKU cannot take a switch. Note that the stop screw sets end position but is not a load lock; for held loads use an external rod lock or SAIL/BSAI variant.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-30 Is Used
Variable-Length Parts Ejector
Tuning the extend stroke by up to 30 mm on-site allows an ejection mechanism to adapt to varying product lengths without changing the entire cylinder setup.
Adjustable Transfer Pusher
A transfer pusher can be precisely dialed in between 670 and 700 mm to align perfectly with shifting conveyor lane widths or pallet stop positions.
Custom Carton Stopping
Packaging lines can field-trim the stop position to handle mixed carton sizes on the fly, ensuring exact placement before secondary processing.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-30 with the SAIJ63X700-30
To replace the discontinued SIJ63X700-30, order the direct replacement SAIJ63X700-30, keeping the same 63 mm bore, 700 mm stroke, 30 mm adjust window, and G3/8 port. Choose the 30 mm adjust window if you need precise 670-700 mm extend tuning. Mounting options include Basic, FA, LB, and TC using standard ISO 15552 interface dimensions. This SKU lacks the -S magnet, so it cannot accept legacy CS1-B/DS1-B sensors. Because the 700 mm stroke exceeds 300 mm, ensure external guides to prevent rod bending and manage side loads. The stop screw only sets end position; it does not hold loads on air loss.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X700-30
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X700-30 FAQ
Yes, the SIJ63X700-30 is discontinued. The direct replacement is the SAIJ63X700-30, which shares the same ISO 15552 interface, 63 mm bore, 700 mm stroke, 30 mm adjust window, and G3/8 port.
The external stop screw provides a 30 mm adjust window, allowing the extend stroke to be shortened from 700 mm down to 670 mm on-site. This stop sets end position only and is not a load lock.
