This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAIJ63X200-20, 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 SIJ63X200-20
The AirTAC SIJ63 Double Rod Adjustable Cylinder SIJ63X200-20 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 SAIJ63X200-20, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-20
The AirTAC SIJ63X200-20 is a discontinued double-acting double-rod ISO 15552 adjustable-stroke cylinder with a 63mm bore and 200mm maximum stroke. An external stop screw lets you trim the extend stroke by up to 20mm on-site, yielding a usable 180-200mm extension. The direct replacement is the SAIJ63X200-20, matching the G3/8 port, M16x1.5 rod thread, and 30mm adjustable cushions.
The stop screw sets the end position but is not a load lock; without live air the piston drifts. For held loads use an external rod lock or the SAIL/BSAI variants. Upgrading to SAIJ brings a two-piece Y-shaped piston seal for lower start-up pressure. This non-magnet SKU cannot take a switch.

Where the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-20 Is Used
Multi-Position Pressing
Trimming the extend stroke by up to 20mm on-site allows a single 63mm bore cylinder to press parts of slightly varying heights without swapping the entire actuator.
Adjustable Transfer Stops
Field-tuning the 180-200mm extend stroke lets operators alter the stop position on a conveyor line to accommodate different package widths on the fly.
Variable Depth Sorting
The external stop screw provides a hard mechanical end position for sorting diverter arms, ensuring consistent placement even if pneumatic pressure fluctuates slightly.
Replacing the Airtac SIJ63 Double Rod Adjustable Cylinder SIJ63X200-20 with the SAIJ63X200-20
To replace the discontinued SIJ63X200-20, order the direct replacement SAIJ63X200-20, reusing your ISO 15552 FA, LB, or TC mounts. The 20mm adjust window provides a 180-200mm extend range; if you need finer tuning, verify the adjust screw tolerance. This non-magnet model (-S omitted) cannot accept legacy CS1-B/DS1-B sensors. For strokes >=300mm, verify side-load guidance to prevent rod binding. Operating speed is 30-800 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAIJ63X200-20
- ✓ 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 SIJ63X200-20 FAQ
Yes, the SIJ63X200-20 is discontinued. The direct replacement is the SAIJ63X200-20, offering the same ISO 15552 interface, 63mm bore, 200mm stroke, 20mm adjust window, G3/8 port, and mounting compatibility.
The external stop screw allows trimming the extend stroke by up to 20mm on-site (usable 180-200mm). The stop sets end position but is not a load lock.
