This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X500-10, 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 SIJ63X500-10
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X500-10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 500mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X500-10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X500-10
The AirTAC SIJ63X500-10 is a double-acting double-rod ISO 15552 adjustable-stroke cylinder. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 490-500 mm stroke. The 63 mm bore features a G3/8 port, M16x1.5 rod thread, and 30 mm adjustable cushions. This SIJ series is discontinued; the direct replacement is the SAIJ63X500-10, sharing the same interface, bore, and force.
The SAIJ upgrade utilizes a two Y-shaped one-way piston seal for low start-up pressure. The stop screw sets end position but is not a load lock; use SAIL or BSAI for held loads.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X500-10 Is Used
Press Fit Tuning
Field-trim the extend stroke by up to 10 mm to set precise press-fit depths without machining custom spacers.
Transfer Stopper
Adjust the end position on-site to accommodate varying pallet lengths on a transfer line.
Pallet Positioning
Fine-tune the extend stop to align pallets precisely against a fixture before clamping.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X500-10 with the SAIJ63X500-10
To replace the discontinued SIJ63X500-10, order the direct replacement SAIJ63X500-10, keeping the 63 mm bore, 500 mm nominal stroke, and 10 mm adjust window. Choose the 10 mm adjust window for fine end-position tuning. Mounting options include FA, LB, and TC brackets. This SKU lacks a -S magnet, so it cannot take a magnetic switch. Because the stroke is 500 mm, ensure external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X500-10
- ✓ 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 SIJ63X500-10 FAQ
Yes, the SIJ63X500-10 is discontinued. The direct replacement is the SAIJ63X500-10, which shares the same ISO 15552 interface, 63 mm bore, 500 mm stroke, 10 mm adjust window, and G3/8 port.
The external stop screw window is 10 mm, allowing a usable extend stroke of 490-500 mm. The stop sets end position and is not a load lock.
