This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X1000-20, 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 SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-20
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-20 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X1000-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-20
The AirTAC SIJ63X1000-20 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 20mm on-site, giving a usable 980-1000mm stroke. The direct replacement is the SAIJ63X1000-20, sharing the same interface, force, and mounting.
The SAIJ upgrade uses an upgraded two Y-shaped one-way piston seal for low start-up pressure and long life. The stop sets end position but is not a load lock; use SAIL or BSAI for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-20 Is Used
Variable-Length Pusher
Tuning a 1000mm extend push-off on a conveyor by up to 20mm on-site to match varying product lengths without swapping the cylinder.
Adjustable End Stop Press
Setting a precise 980-1000mm end position for a light-duty assembly press, allowing 20mm of field adjustment for different tooling heights.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-20 with the SAIJ63X1000-20
Replace the SIJ63X1000-20 directly with the SAIJ63X1000-20, retaining the 20mm adjust window, G3/8 port, and 30mm adjustable cushions. Choose FA, LB, or TC ISO 15552 mountings. This SKU lacks a -S magnet, so it cannot take a magnetic switch. For the 1000mm stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X1000-20
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X1000-20 FAQ
Yes, the SIJ63X1000-20 is discontinued. The direct replacement is the SAIJ63X1000-20, which shares the same ISO 15552 interface, 63mm bore, 1000mm stroke, 20mm adjust window, G3/8 port, and mounting options.
The external stop screw provides a 20mm adjust window, allowing you to trim the extend stroke on-site from the 1000mm maximum down to 980mm. The stop sets end position only; it is not a load lock.
