This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X200-10S, 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 SIJ63X200-10S
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X200-10S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø63mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAIJ63X200-10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-10S
The AirTAC SIJ63X200-10S is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63 mm bore and 200 mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 190-200 mm extension window. The stop sets the end position but is not a load lock. The -S suffix denotes a built-in piston magnet for legacy CS1-B/DS1-B switches.
The direct replacement is the SAIJ63X200-10S, matching the ISO 15552 mounting interface, bore, stroke, force, and port. The SAIJ family features an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. Note that a plain cylinder drifts on air loss; for held loads use an external rod lock, pilot-operated check valve, or the SAIL/BSAI lock variants.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-10S Is Used
Press Fit Dialing
Fine-tune the 190-200 mm extend endpoint on-site to set precise insertion depth for bearing press fits without machining custom spacers.
Divertor Gate Adjustment
Micro-adjust the actuator stop to alter the gate extension distance, accommodating varying package widths on a sorting line.
Pallet Stop Positioning
Trim the extend stroke by up to 10 mm to dial in the exact contact point for pallet halting, ensuring repeatable indexing.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-10S with the SAIJ63X200-10S
To replace the discontinued SIJ63X200-10S, order the SAIJ63X200-10S, which offers identical ISO 15552 mounting, 200 mm nominal stroke, and 10 mm adjust window. Choose the 10 mm adjust window if you need fine end-position tuning within a 190-200 mm extend range. Mounting options include Basic, FA, LB, and TC. The -S suffix ensures a piston magnet for switch sensing. For strokes of 300 mm or longer, verify side-load limits to prevent excessive guide wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X200-10S
- ✓ 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 SIJ63X200-10S FAQ
Yes, the SIJ63X200-10S is discontinued. The direct replacement is the SAIJ63X200-10S, which matches the ISO 15552 interface, 63 mm bore, 200 mm stroke, 10 mm adjust window, G3/8 port, and mounting options. The SAIJ family uses an upgraded piston seal and current AirTAC switches.
The external stop screw offers a 10 mm adjust window, allowing the extend stroke to be shortened from the 200 mm maximum down to 190 mm. The cylinder operates at 30-800 mm/s and uses a G3/8 port.
